Black Surfperch by Ron DeCloux

1

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii

Order: Perciformes

Suborder:Labroidei

Family: Embiotocidae (surfperches)

Genus/species: Embiotoca jacksoni

GENERAL CHARACTERISTICS: Their body is deep and compressed. Their colors are various shades of brown, red, green above, yellowish below, darker bars on sides with a blue bar on base of anal fin. Note a mustache-like black bar on upper lip. .

Length up to 39 cm (15 in)

DISTRIBUTION/HABITAT: Black Surfperch are found from Fort Bragg, California to Punta Abreojos, Baja California, Mexico nearshore reefs and kelp forests. They are also found over sand, and in estuaries near algae.

Usually within 1 m (3 ft) of the substrate.

DIET IN THE WILD: E. jacksoni feed on worms, crustaceans and mollusks. They are also cleaner fish of conspecifics as well as other species.

REPRODUCTION: Summer is the peak breeding season. Fertilization is internal. Viviparous; young embryos are nourished internally and are quite large as newborns.

Lovely Poison Dart Frog by Ron DeCloux

1

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Amphibia

Order: Anura

Family: Dendrobatidae

Genus/species: Phyllobates lugubris

GENERAL CHARACTERISTICS: Small frogs, less than an inch in length, with the females slightly larger than the males. The head is longer than wide with a round snout. The back is jet black with paired dorsolateral stripes, of various colors including yellow, orange, gold or turquoise. They also have a thinner lighter turquoise or white ventrolateral stripe on each side from the tip of the snout to and along the front limbs.

DISTRIBUTION/HABITAT: This species inhabits the humid lowland and the premontane zone along the Atlantic coast of southeastern Nicaragua through Costa Rica to Central Panama.

The frogs live in the leaf litter of the forest floor, near slow-moving water.

DIET IN THE WILD: Eat ants, mites, beetles, and spiders.

REPRODUCTION: Breeding occurs in the wet season. Males call to attract females, with a chortle that sounds like a hand rubbing an inflated balloon. A pair works together to create a ground nest in dry leaf litter. The female then deposits her eggs, which the male fertilizes. The male takes over and periodically moistens the eggs in the nest until the eggs hatch. He then carries 5 to 10 tadpoles at a time on his back to aquatic rearing sites. In about 2 months the tadpoles metamorphose into froglets that are about a half an inch long.

MORTALITY/LONGEVITY: Most poison dart frogs can live from 10 to 15 years in captivity. In general poison dart frogs have few predators. Their bright colors warn potential predators that they are toxic, even though in reality many of them merely taste bad because of sour but low potency toxins in their skins. Thus this group provides examples of both aposematic coloration and Batesian mimicry.

CONSERVATION: IUCN Red List Least concern (LC) This species is relatively safe due to its wide distribution, tolerance to modification to its habitat, and its fairly large population.

REMARKS: Some South American natives capture other members of this genus (Phyllobates terribilis, P. bicolor, P. aurotaenia) to poison blow-gun darts. However, Phyllobates lugubris is not as toxic as other species in its genus and has not been documented to have been hunted primarily for its poison

Phyllobates lugubris is sympatric with another species, Eleutherodactylus gaigeae, known as the "false poison-dart frog." This species mimics the appearance of P. lugubris in order to fend off predators, by having two paired red stripes running the length of the body. However, E. gaigae is a non-toxic mimic and does not produce batrachotoxins.

Color of Life note

Biofluorescence results from the absorption of electromagnetic radiation at one wavelength by an organism, followed by its reemission at a longer and lower energy wavelength, visually resulting in green, orange, and red emission coloration. Many species of mantis shrimp, for example, make use of fluorescent body parts when in threat display in order to intimidate or confuse either a predator or a competing male.

TAXONOMY

Kingdom: Animalia

Phylum:Arthropoda

Subphylum: Crustacea

Class: Malacostraca

Order: Stomatopoda

Family: Odontodactylidae

Genus/species: Odontodactylus scyllarus

GENERAL CHARACTERISTICS: Beautifully colored in peacock colors of greens, blues, and reds. Has a green body, blue head, green antennal scales, red limbs. The body is elongated with a long, flattened , blue tail and ranges in size from 3–18 cm (1.2-7.0 in). Highly noticeable is the pair of clubbed-shaped, praying mantis-like claws.

DISTRIBUTION/HABITATS: Indo-Pacific Habitat: warm salt water and builds U-shaped burrows in gravel substrates. Depth ranges from 3-40 m (10-131 ft).

DIET IN THE WILD: Feeds on other shrimp, worms, snails, crabs, mollusks. Lies in wait for prey in front of burrow, then swims out and quickly crushes prey with a strong, powerful smash. The claw moves so quickly it generates cavitation bubbles, which explode with a second powerful burst. The speed with which the claw moves through the watergenerates a force 100 times the shrimp’s body weight.

REPRODUCTION: Monogamous. O. scyllarus mate, spawn, brood, and hatch their eggs in their burrows.

LONGEVITY: Often live in pairs for their entire lifetime (4-6 years).

PREDATORS: Yellow Fin tuna

CONSERVATION: IUCN Not Evaluated

REMARKS: Large peacock mantis shrimp generate forces powerful enough to crush the shell of a large conch, and have been known in captivity to break the glass of their tanks! Striking speed of 50+ mph.

The amazingly complex eyes of mantis shrimp detect 12 base colors (compared to our 3). They also can discern ultraviolet, infrared frequencies, and the polarization of light! .

Swell Shark (eggs lower left) by Ron DeCloux

1

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Elasmobranchii (sharks and rays)

Order: Carcharhiniformes (Ground sharks; characterized by the presence of a nictitating membrane over the eye, two dorsal fins, an anal fin, and five gill slits.)

Family: Scyliorhinidae (Cat sharks; elongated cat-like eyes and a patterned appearance, ranging from stripes to patches to spots)

Genus/species: Cephaloscyllium ventriosum

GENERAL CHARACTERISTICS: Swell sharks have a stout body with flat, broad head; short snout; huge mouth, proportionally larger that the great white shark (Carcharodon carcharias). Teeth are at front of jaws with dagger-like central point and 1-2 small points on each side; two dorsal fins: first much larger, with origin over pelvic fins, second dorsal fin considerably smaller than first, its origin over origin of anal fin. The body is light brown with dark patches covered with black dots.

Length up to 3.2 ft.

DISTRIBUTION/HABITAT: Central California to southern Mexico; also reported near central Chile.

Found in rocky reefs and kelp forests, from surface to 460 m (1500 ft), in temperate and subtropical waters.

DIET IN THE WILD: Cephaloscyllium ventriosum is nocturnal; feeding on crustaceans and fishes, (often blacksmiths). They are lie-in-wait predators that sit on the bottom with wide-open mouth, ready to ambush unsuspecting prey. (slowly opens jaws; lies in wait for prey to swim inside).

REPRODUCTION: Oviparous; female lays amber-colored egg cases that hatch in 8–10 months. Egg case (“mermaid’s purse”) is 9 – 13 centimeters (3.5 - 5 inches) long, 3 – 6 centimeters (1 - 2.3 inches) wide. Young have enlarged toothlike denticles on the back that help them break through egg cases. Pups measure 14 – 15 centimeters (5.5-6 in) at birth; immediately feed on their own.

Embryos may be eaten by snails that bore through egg cases.

PREDATORS: If caught it is, usually it will be released because its flesh is of poor quality. Embryos may be eaten by snails that bore through egg cases. Life span: 25 or more years

CONSERVATION: IUCN Red List: least concern species

REMARKS: C. ventriosum hides in caves and crevices during normal aquarium hours. the day, and so is often not to be seen during aquarium hours. Common and specific (ventriosum = “largebelly”) names come from its ability to take in water that makes it appear up to twice as large as its normal size, a difficult meal for predators to bite or to remove from a crevice. If caught and brought to the surface, it can swell its body with air.

When caught by fishermen and brought out of water, the release of gulped water/air can cause the swell shark to “bark”.

Occurs in aggregations while resting, sometimes piled one on top of the other.

Bluespotted Ribbontail Stingray by Ron DeCloux

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Chondrichthyes

Subclass: Elasmobranchii (sharks and rays)

Order: Myliobatiformes (Stingrays)

Family: Dasyatidae (Stingrays)

Genus/species: Taeniura lymma

GENERAL CHARACTERISTICS: Large bright blue spots on a grey-brown to yellow, olive-green or reddish brown oval, elongated disc with lateral blue side-stripes along the tail. The snout is rounded and angular. When viewed from below the white belly blends in with the sunny waters above and when viewed from above, the dark, mottled back blends in with the dark ocean floor below. Disc diameter to 25 cm (9.8 inches).

DISTRIBUTION/HABITAT: Indo-West Pacific around coral reefs and sandy bottoms to a debt of 20 meters (66 feet).

DIET IN THE WILD: Prey is often detected through electroreception, a system which senses the electrical fields produced by the prey. Within the mouth are two plates, which are used for crushing mollusks, worms, shrimps, and crabs.

REPRODUCTION: Ovoviviparous; the egg shell is weakly formed and young hatch inside the female; they are nourished by their yolk sac and then ‘born’ live.

PREDATION: The hammerhead shark uses the cartilaginous projections form the side of their heads to pin them down to the bottom of the substrate while taking bites from the stingray's disc. The hammerhead is able to avoid being stung by the poisonous spines on the rays tail by pinning the stingray down.

CONSERVATION: IUCN Red List: Near Threatened

Destruction of coral reef habitat poses the most significant threat to the species. Also harm is caused by poisoning through farm pesticides and fertilizers running into the sea, by dynamite fishing, and by cyanide, used to capture reef animals for the pet trade

REMARKS: At the tip of the tail are two sharp venomous spines (can be regenerated) which permit this ray to strike at enemies forward of its head. Venom is produced and delivered into narrow groves running lengthwise along the underside of the stinger. The entire structure is covered by a thin layer of skin which, when broken, releases its venom into its victim.

TAXONOMY

Kingdom: Animalia

Phylum:Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Perciformes (Perch-likes)

Family: Serranidae (Sea Basses: Groupers, and Fairy Basslets)

Genus/species: Pseudanthias pleurotaenia

GENERAL CHARACTERISTICS: Sexually dichromatic. The male is orange-red to magenta, one large violet square on each side of its body (thus the common name), elongate third dorsal spine. Coloration and size of “square” highly variable among individuals; female less colorful. On many individuals, the magenta square spot appears to glow like a neon light.

Length up to 20 cm (8 in)

DISTRIBUTION/HABITAT: Indonesia to Samoa, Japan and the eastern Indian Ocean over steep, current-swept seaward dropoffs, 10–180 m (30-550 ft), but typically below 25 m (75 ft) depth.

DIET IN THE WILD: Small crustaceans and fish eggs.

REPRODUCTION: Sequential hermaphrodite: can change sex from female to male. All Squarespot Anthiasis begin life as females. All males are sexually reversed females. Sex reversal is due to environmental or social factors ensureing there will always be a male and a female to reproduce.

CONSERVATION: IUCN Red List Least Concern (LC)

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii

Order: Scorpaeniformes

Family: Scorpaenidae (Scorpionfishes and Their Allies)

Genus/species: Pterois volitans

GENERAL CHARACTERISTICS: Length to 38 cm (54 inches). Compressed body with a large head from 1/3 to 1/2 the standard length. Greatly enlarged pectoral fins and elongate dorsal fins. Vertically colored brownish bars interspersed with fine white lines. Two visually identical species have been introduced into the north-west Atlantic Ocean, Caribbean Sea and the Gulf of Mexico making positive identification only by genetic analysis.

DISTRIBUTION/HABITAT: P. volitans occurs throughout most of Oceania being native to the western Pacific Ocean and introduced to the Atlantic possibly through the aquarium trade. Inhabits coral reefs and lagoons, turbid inshore areas to depths to 50 m (160 ft).

DIET IN THE WILD: A voracious nocturnal predator of small fishes, shrimp and crabs. Corners and traps prey with its widespread pectoral fins.

PREDATORS: Other than cannibalism, there are few documented natural predators of the lionfish. Also native groupers in the Bahamas consume them. Finally despite their venomous spines, lionfish are caught by humans for food.

LIFESPAN 10 years

CONSERVATION IUCN Not Evaluated

REMARKS: Venomous glands at the base of dorsal, anal and pelvic fin spines are capable of inflicting severe and painful wounds. The venom contains a neurotoxin which reduces the transmission chemical signals to the muscles, as well as affecting the cardiovascular system. Doctors suggest soaking the afflicted area in very hot water to denature the venom’s proteins. Experimental evidence suggests that commercial stonefish antivenom does have some detoxifying effect on lionfish venom.

Electric Eel (knifefish) by Ron DeCloux

1

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Superclass: Osteichthyes

Class: Actinopterygii (ray-finned fishes)

Order: Gymnotiformes (Knifefishes)

Family: Gymnotidae (Naked-back knifefishes)

Genus/species: Electrophorus electricus

GENERAL CHARACTERISTICS: The eels body is elongated and cylindrical, almost without scales; head flattened; mouth large with one row of conical teeth on each jaw; presence of three abdominal pairs of electric organs. The color is dark with anterior ventral part yellowish. They have a very long anal fin.

Length up to 2.5 m (8 feet). Weight up to 20 kg (44 pounds).

DISTRIBUTION/HABITAT: Tropical. Amazon Basin: Orinoco, and related areas in northern South America. The Electric Eel is found in lowland backwaters and muddy river bottoms, never fast-flowing waters. During daylight, retreats to recessed hiding places shared with conspecifics.

DIET IN THE WILD: Juveniles eat invertebrates such as shrimp; adults prey on fish and small mammals.

MORTALITY/LONGEVITY: Life span: in captivity males to 15 years, females to 20+.

REPRODUCTION: E. electricus males construct foam nests and guard the growing larvae. First-born larvae prey on other eggs and embryos coming from late spawning batches. In mid-January when the first seasonal rains flood the breeding area, causing the about 10 cm long young eels to disperse.

REMARKS:

NOT A TRUE EEL. True eels lack pectoral and pelvic fins. Unlike “true” eels in the Order Anguilliformes, they are obligate air breathers, taking up to 80% of their oxygen directly from the air, an adaptation for survival in poorly oxygenated water. The long undulating anal fin allows the electric eel to move backwards or forwards

Though not an aggressive fish, it can produce enough voltage to severely injure humans. If an electric eel fires a series of charges, each successive charge is less powerful. Aquarists stimulate several discharges before attempting to handle the animal safely. These eels also have two other, much smaller sets of electric organs, used for orientation and finding prey,

They are active nocturnally.

The long undulating anal fin allows the electric eel to move backwards or forwards. About half the musculature has been converted into electric organs which produce up to 650 V. These eels use their electricity to stun the fish they prey upon, as well as for defense.

As the eel matures it develops cataracts leading to blindness relying only on its electrical senses. (Similar to the elephant fish with poor vision)

CONSERVATION: IUCN Red List; Least Concern.

Warty Sea Cucumber by Ron DeCloux

TAXONOMY

Kingdom: Animalia

Phylum: Echinodermata

Class: Holothuroideaia

Order: Aspidochirotida

Family: Stichopodidae

Genus/species: Parastichopus parvimensis

GENERAL CHARACTERISTICS: Colored brown above, lighter below. Conical black-tipped papillae on the dorsal side provide the common name. The mouth and anus are on opposite ends of their cylindrical bodies. Tube feet aide in gathering food as well as ambulating.Length to 25 cm (10 inches).

DISTRIBUTION/HABITAT: Monterey Bay, California to Baja California. Found on sandy or muddy-sandy soft bottoms between rocks or in eelgrass beds. Sub tidal to 27 m (89 feet) in depth.

DIET: Digests organic detritus and small organisms in soft sediments.

REPRODUCTION?DEVELOPMENT: Have separate sexes (look alike), and eggs are fertilized externally. Broadcast spawning usually takes place in November, and each female can produce thousands of eggs. After fertilization, a larva is formed which metamorphoses into a Sea Cucumber after a few weeks.

MORTALITY/LONGEVITY: Eaten by sea stars including the sunflower star. Sea otters and humans are also predators. Lifespan estimated to be 5-10 years in the wild.

CONSERVATION: IUCN Red list; Not Evaluated

REMARKS: Holothuroids differ from echinoderms, because they have a water vascular system full of body fluid rather than sea water. Like other echinoderms, cucumbers have a calcareous skeleton; but in their case it is only vestigial, composed of plates and spicules of lime buried in the skin and serving merely to stiffen the body wall. Respiratory trees are the lungs of a sea cucumber. These hollow branched organs lie inside the body cavity on either side of the posterior intestine. The base of the tree connects to a muscular cavity, or cloaca. Oxygen is transferred across the thin membrane into the fluids of the body cavity. When the oxygen is depleted, the main body wall contracts to squeeze water out of the trees.

When threatened, it can expel all its internal organs through its anus (evisceration) and grow new ones in 2-4 weeks. It can also expel sticky filaments to ensnare or confuse predators. Warty sea cucumbers and their related species are sometimes called the “earthworms of the sea,” as they cultivate the seafloor in much the same manner as earthworms cultivate the soil. Oral tube feet around the mouth are covered with a sticky mucus that traps food particles from the seafloor's sediment and mud. In areas where overfishing has reduced the population of sea cucumbers, the seafloor hardens, thus destroying a habitat for other bottom-dwelling creatures. Can walk on tube feet if stressed up to one yard every 15 min..

Humans eat a variety of sea cucumber species, including Warty sea cucumbers. The demand is greatest in Asian countries, for consumption and folk medicine applications. It is considered to be widely overfished.

False Clownfish aka Nemo tending eggs by Ron DeCloux

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Perciformes (Perch-likes)

Family: Pomacentridae (Damselfishes)

Subfamily: Amphiprioninae (anemonefishes)

Genus/species: Amphiprion ocellaris

GENERAL CHARACTERISTICS: Adults are orange with three broad vertical white bands with thin black margins. Females are larger than males. Similar to the Clown Anemonefish (Amphiprion percula) but has 11 spines in the dorsal fin compared to 10, while the spiny part of the dorsal fin is also taller.

Length up to 9 cm (3.5 inches)

DISTRIBUTION/HABITAT: Found among tropical Pacific Ocean. coral reefs. They sleep and feed among the

tentacles of their host anemone. Stichodactyla gigantea, Stichodactyla mertensi, as well as the anemone Heteractis magnifica. The False Clownfish is usually found at depths of about 15 m (50 ft).

DIET IN THE WILD: Feeds primarily on zooplankton, especially copepods and also on filamentous algae.

REPRODUCTION: A. ocellaris breeds continuously at the Steinhart. Adhesive eggs are laid on a patch of cleared rock near the host anemone’s base and guarded by the male. Eggs hatch after 10 days. The tiny transparent planktonic larvae swim away from the anemone. Two weeks later the larvae metamorphose into small fish. As protandrous hermaphrodites; all individuals mature as males, and all females are sex-reversed males. In the absence of a female the largest male will turn into a female.

Longevity: Up to 12 years in captivity

CONSERVATION: IUCN Red List Not Evaluated

REMARKS. Clownfish and anemone display a classic case of mutualism. Clownfish become resistant to their host by gradually (matter of minutes to days) acquiring a covering of mucus

by brushing against the tentacles of their host. Once the fish has become chemosensorilly camouflaged, the host anemone’s nematocysts do not sting the clownfish.

Some of the anemone’s nutrition results from the clownfish’s activities; clownfish gain protection among the anemone’s nematocysts.

Nemo and his parents in Finding Nemo resemble this species. That said, Marlin, Nemo’s father, given the scenario would have changed into a female following the death of Nemo’s mother and remained near his host anemone, rather than swimming to Sydney. But then the film makers wouldn’t have a narrative to support this film! The name “Nemo” has found its way into FishBase as a common name for this species in the USA.

Orangespot Stingray by Ron DeCloux

1

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Chondrichthyes (cartilaginous fishes)

Subclass: Elasmobranchii (sharks, rays and skates)

Order: Myliobatiformes

Family: Potamotrygonidae (river stingrays)

Genus/species: Potamotrygon motoro

GENERAL CHARACTERISTICS:GENERAL CHARACTERISTICS: Orange-spot Stingrays have an oval disc, with a greyish-brown upper surface patterned with distinct yellow-orange spots, and a white underside. Like most rays, flat teeth are used to grip and crush prey that is sucked into the ventral mouth. Note periscoping eyes which protrude from sand when buried. Olfaction is a major and well-developed means of perception for these stingrays; their olfactory organs are situated in laterally placed cartilaginous capsules on the top of the head. The spine on the tip of the tail is capable of delivering a painful sting. Rays have an accessory respiratory opening, the Spiracle which is an adapted gill slit which has migrated to the top of the stingray. When the stingray is resting on the bottom the spiracle allows them to breathe.

Length up to 1 m (3 ft.) and weight to 15 kg (33 lb.).

DISTRIBUTION: South America: Uruguay, Paraná- Paraguay, Orinoco, and Amazon Basins.

HABITAT: Found in freshwater calm waters, especially on the sandy margins of lagoons, brooks and streams. Able to tolerate only a narrow range of salinities. Lost ability to retain urea decreasing osmolarity for fresh water unlike salt water relatives.

DIET IN THE WILD: They feed mostly on benthic hard-shelled invertebrates, such as clams, mussels, and crustaceans and also on worms, insect larvae, and small fishes.

REPRODUCTION: Fertilization is internal with the male attaches himself to a female by firmly clamping his jaws onto the posterior margin of her disk, sometimes leaving prominent bite marks. Females produce eggs that hatch inside the female and are then ‘born’ live after a gestation period of no more than three months. The litter size varies, from 3 to 21 young.

LIFESPAN: Maximum of 15 years in captivity.

CONSERVATION: IUCN Red list Data Deficient (DD)

REMARKS: P. motoro is one of the seven species of this genus inhabiting southern South America.

The Operculum pupillare inside the eye which controls the amount of light entering the eye. In dim light it will retract allowing greater light in and better vision at night.

They are not dangerous unless stepped on or threatened.

Fishermen also harpoon these rays during floods when they are found resting over vegetation in shallow water. P.motoro apparently has delicious meat.

Sixbar Wrasse by Ron DeCloux

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Perciformes (Perch-likes)

Family: Labridae (Wrasses)

Genus/species: Thalassoma hardwicke

GENERAL CHACTERISTICS: Adult is pastel blue to pale green with six dark, vertical bars on their body, the last two saddling the tail. The head has a distinct ‘daisy’ print around the eyes made of a few different pastel colors (e.g., pink bands radiating from the eye) in larger adults. Terminal males are gaudier than primary males. Max length: 20 cm (8 inches).

DISTRIBUTION/HABITAT: Found in the tropical Indo-Pacific in shallow lagoons and seaward reefs. Depth to15 m (50 ft.).

DIET IN THE WILD: Carnivore on benthic and planktonic crustaceans, other motile invertebrates and small fishes.

REPRODUCTION: Protogynous hermaphrodite; Hermaphroditism occurs when a given individual in a species possesses both male and female reproductive organs, or can alternate between possessing first one, and then the other. The most common pattern is for a female to change into a male (protogyny). This often happens when a large dominant male is removed by a predator. Within a few days, the largest female in the harem becomes a dominant male and takes over the missing male's function. This pattern is common in coral reef fishes, such as parrotfishes, wrasses, and groupers.

T.hardwicke is a pelagic spawner meaning water currents widely disperse the young. The eggs, embryos and larvae of pelagic spawners contain oil globules or have a high water content. As a result, they are buoyant and are widely dispersed by currents. The downside is that mortality is high, because they can be eaten so easily by pelagic predators. Pelagic spawners who live in or around coral reefs can spawn a small number of eggs almost daily over a period of months.

CONSERVATION: IUCN; least concern

REMARKS: Occur in small, loose groups.

Red Abalone by Ron DeCloux

2

Color of Life note: Iridescence is caused by two or more semi-transparent, inorganic and/or organic surfaces

that cause multiple light reflections. An example found in our tidepool is the Red Abalone inner shell surface which produces an impressive vibrant luster when exposed to light.

The aragonite and conchiolin secreted by the abalone in forms a crystalline structure that reflects light, causing the shell’s iridescence. The inner surface of the shell is known as mother-of-pearl, or nacre.

Ref: California Academy of Sciences, Color of Life Exhibit 2015

Jewelry is still made from abalone shells and is quite popular.

Ref: www.best-deal.com/search/landing/query/red+abalone+shells...

TAXONOMY

Phylum: Mollusca

Class: Gastropoda (slugs, snails, nudibranchs, abalone)

Order: Archaeogastropoda (sea snails)

Family: Haliotidae (abalones)

Genus/species: Haliotis rufescens

GENERAL CHARACTERISTICS: The red abalone is a large limpet-like snail with a flattened and rounded shell. The shell can reach up to 30 cm (11.8 in) in length and is usually brick red and overgrown with fouling organisms. Color varies with diet and varies between aquamarine, green, or white. Water enters anteriorly through row of holes parallel to the rim of the shell and exits posteriorly carrying waste products and gametes. When in danger, the abalone clamps its shell tightly to the substrate, protecting soft parts of its body. The shell’s color is influenced by the animal’s diet. The red color is from the pigment phycoerythrin consumed in its red alga diet. Color varies with a diet of brown algae (varies between aquamarine, green, or white).

DISTRIBUTION/HABITAT: Red abalone are found from Oregon to Baja California. They are uncommon in the lower intertidal zone in rocky areas with heavy surf. Most are now found at 6 to 17 m (20 to 56 ft) depth in central California.

DIET IN THE WILD: Small abalones feed on diatoms and algae; larger animals browse the seaweeds. Red abalone eat algae, especially red and brown species. Usually foraging at night, they trap drifting pieces of algae (kelp) with the tentacles that extend from the foot. The algae is then carried by the foot to the mouth, and is torn and consumed with by the radula.

PREDATORS: Sea stars, crabs, octopuses, sea otters and human divers are among the abalone's primary predators.

REPRODUCTION and DEVELOPMENT: After spawning takes place, fertilized eggs sink. Larvae develop in the plankton until they settle to the bottom, metamorphose, and begin to graze. Growth slows with increasing size and age. Mortality is very high in the planktonic stages. Mature individuals can live more than 20 years.

REMARKS: Red abalone are highly endangered due to overexploitation by the abalone fishery. The population plummeted in the late twentieth century, but poaching continues to be a problem. California passed many strict regulations to protect the red abalone: abalone smaller than 20 cm (8 in) in diameter are protected, the canning of abalone is prohibited, and the shipment of fresh or frozen meat out of California is prohibited. Red abalone is the only species that can still be fished. Aquacultured abalone is now increasingly available.

Abalone blood is blue green and cannot clot making injury possibly fatal.

American Alligator (male albino) by Ron DeCloux

2

Color of Life note Color Conceals:

White alligators are prime example of what happens when color does not conceal. Albinism (total lack of pigment) results from a genetic change which puts the alligators at great risk because they are easy to spot by predators in their environment. Ref. California Academy of Sciences Color of Life Exhibit 2015

TAXONOMY

Kingdom: Animalia

Phylum: Chordata (presense of a notochord (an internal skeletal rod that provides support) during some stage of the animal's development).

Class: Reptilia (snakes, worm lizards, lizards, alligators, caimans, crocodiles, tortoises, turtles, and tuataras).

Order: Crocodylia (crocodiles, alligators, caimans and the gharial).

Family: Alligatoridae (Alligators and Caimans).

Genus/species: Alligator mississippiensis

GENERAL CHARACTERISTICS: Alligators have a muscular laterally flattened tails for propulsion and defense. Dorsally their skin is armored bony plates called osteoderms and scutes. They have four short legs with five toes on the front and four on the back. The snout is broad with upper facing nostrils to aide in breathing while major portion of the body is under water.

Differences between alligators and crocodiles:

1. Alligators tend to have wide, U-shaped, rounded snouts, while crocodiles tend to have longer, more pointed, V-shaped snouts.

2. The large lower fourth tooth of an alligator fits into a socket in the upper jaw and is not seen when the mouth is closed, whereas in crocodiles this tooth is visible.

3. Alligators live in freshwater; crocodiles tend to inhabit salt water.

4. On average alligators are smaller than crocodiles.

Alligators have between 74 and 80 teeth, which are replaced as they wear down; an alligator can go through 2,000 to 3,000 teeth in a lifetime.

The average alligator adult size for a female is 2.6 m (8.2 ft) and for males is 3.4 m (11.2 ft). Exceptionally large males can weigh over 450 kg (1000 pounds).

DISTRIBUTION/HABITAT; Southeastern United States, from North Carolina to the Rio Grande in Texas. Habitat: Usually found in freshwater, especially in slow-moving rivers. They are also found in swamps, marshes, and lakes. They can tolerate salt water only briefly. They dig gator holes for use during low water periods in the summer.

DIET IN THE WILD: Alligators eat almost anything, but primarily consume fish, birds, turtles, mammals and amphibians.

Alligators spin on their long axis to rip off bite sized portions small enough to swallow when eating large animals such as deer.

Since they are ectothermic their need for food is decreased allowing them to survive without food for up to 3 years.

they are a mild threat to humans with approximately one death every 5 years reported between 1973-1990.

ACADEMY DIET: Claude is generally fed combination of small chickens, large rats, fish and a special micronutrient gel.

He is fed once a week always associated with a training session receiving 1-2 pounds of food per week. 4-14-18

REPRODUCTION: The temperature at which American alligator eggs develop determines their sex. Eggs which are hatched at 90 to 93 degrees Fahrenheit become males, while those at 82 to 86 degrees Fehrenheit become females. Intermediate temperature ranges yield a mix of both male and females. The hatchings grow rapidly, averaging over 1 foot of growth for each year of life. Both sexes reach sexual maturity at around 6 feet in length,

LONGEVITY: Wild: 35 to 50 years, captivity: 65 to 80 years.

CONSERVATION: IUCN Least Concern (LC), Some limited hunting is allowed in some states.

REMARKS: The California Academy of Sciences has one white pink eyed albino alligator born on 9-15-1995.

Recent Claude stats

2010 length 2.6m (8.5 feet), weigh 82 kg (181 pounds).

6-10-12 length 9.0 feet, weight 190 pounds.

6-10-13 length 9.5 feet, weight 222 pounds.

Claud's vision is poor because of lack of pigment which protects the eye from ultraviolet rays of the sun.

Leucistic alligators are are also genetically recessive but often have some dark patches on their white bodies. They have blue or brown eyes color thus are not albinos.

Copper Rockfish by Ron DeCloux

TAXONOMY

Kingdom: Animalia

Phylum: Chordata

Class: Actinopterygii (ray-finned fishes)

Order: Scorpaeniformes (Scorpionfishes and flatheads)

Family: Sebastidae (Rockfishes, rockcods and thornyheads)

Genus/species: Sebastes caurinus

GENERAL CHARACTERISTICS: Deep, stout body. Color highly variable; dark brown or olive to pink or orange-red above, with patches of pink-copper and occasionally yellow.. Fins primarily copper, often dusky. They are distinguished from other rockfish species by the clear areas along the posterior two thirds of the lateral lines, and in having a whitish underside, usually with two dark bands radiating from eye. Dorsal fin membrane not deeply incised.

Length up to 57 cm (22.44 in). Weight up to 2.6 kg (5.73 pounds).

DISTRIBUTION/HABITAT: The Copper Rockfish is found in the Gulf of Alaska to central Baja California among rock-sand bottoms 10–180m (33-600 ft) deep. They are solitary, bottom-dwelling reef fish which frequently live near pinnacles and wrecks. Adults avoid warm water; thus live deeper in southern California than further north.

DIET IN THE WILD: Juveniles consume plankton. Adults are mainly benthic (organisms living on or in sea or lake bottoms) feedering on fishes, crabs, mysid shrimp, prawns, amphipods, octopuses, polychaete worms and fish eggs.

REPRODUCTION: Mature at 4-8 years. Fertilization is internal. via copulation and the transfer of sperm is through a modified urogenital papilla on the male.

The females store sperm in the ovaries for several months until ovulation then fertilizes the eggs. They are viviparous. The larvae mature in shallow water.. Larvae are planktonic maturing in shallow water becoming sexually mature at around five years.

LONGEVITY: Live to at least 55 years.

PREDATORS: Lingcod (Ophiodon elongatus) and also other large predators.

CONSERVATION: IUCN: No special statu

REMARKS: Rockfish species that live in the California coastal waters, are very important to commercial and sport fisheries. The 60 species of rockfish caught account for 34% by weight of all sportfish landed in California.

Copper Rockfish caught off the coast of British Columbia and California are sold alive at a premium price to Asian fish markets.

Peacock Mantis Shrimp by Ron DeCloux

Color of Life note

Biofluorescence results from the absorption of electromagnetic radiation at one wavelength by an organism, followed by its reemission at a longer and lower energy wavelength, visually resulting in green, orange, and red emission coloration. Many species of mantis shrimp, for example, make use of fluorescent body parts when in threat display in order to intimidate or confuse either a predator or a competing male.

Ref: Color sources, California Academy of Sciences Docent program May 2015

PLOS one Biofluorescence journals.plos.org/plosone/article?id=10.1371/journal.pone...

TAXONOMY

Kingdom: Animalia

Phylum:Arthropoda

Subphylum: Crustacea

Class: Malacostraca

Order: Stomatopoda

Family: Odontodactylidae

Genus/species: Odontodactylus scyllarus

GENERAL CHARACTERISTICS: Beautifully colored in peacock colors of greens, blues, and reds. Has a green body, blue head, green antennal scales, red limbs. The body is elongated with a long, flattened , blue tail and ranges in size from 3–18 cm (1.2-7.0 in). Highly noticeable is the pair of clubbed-shaped, praying mantis-like claws.

DISTRIBUTION/HABITATS: Indo-Pacific Habitat: warm salt water and builds U-shaped burrows in gravel substrates. Depth ranges from 3-40 m (10-131 ft).

DIET IN THE WILD: Feeds on other shrimp, worms, snails, crabs, mollusks. Lies in wait for prey in front of burrow, then swims out and quickly crushes prey with a strong, powerful smash. The claw moves so quickly it generates cavitation bubbles, which explode with a second powerful burst. The speed with which the claw moves through the watergenerates a force 100 times the shrimp’s body weight.

REPRODUCTION: Monogamous. O. scyllarus mate, spawn, brood, and hatch their eggs in their burrows.

LONGEVITY: Often live in pairs for their entire lifetime (4-6 years).

PREDATORS: Yellow Fin tuna

CONSERVATION: IUCN Not Evaluated

REMARKS: Large peacock mantis shrimp generate forces powerful enough to crush the shell of a large conch, and have been known in captivity to break the glass of their tanks! Striking speed of 50+ mph.

The amazingly complex eyes of mantis shrimp detect 12 base colors (compared to our 3). They also can discern ultraviolet, infrared frequencies, and the polarization of light! .
