La Rana Flecha Azul puede presentar varios colores que van del azul claro a tonalidades púrpura. Es este color el que advierte a los depredadores de su toxicidad y una de sus características más destacadas. Poseen, además, una serie de manchas oscuras en la piel que siguen un patrón único para cada rana y distinguen a unos individuos de otros. Son muy territoriales y agresivas, tanto con los miembros de su misma especie como con otros animales. Las glándulas de su piel segregan toxinas que utilizan como defensa frente a sus atacantes potenciales. La esperanza de vida de esta rana, que se encuentra al sur de Surinam y en Brasil, es de cuatro a seis años (si bien en cautiverio llegan a vivir el doble). Su distribución, muy limitada, así como la destrucción del hábitat, la han puesto en una situación vulnerable.
The Regal Ring-necked Snake (Diadophis punctatus regalis) is full of unique behaviors from curling its tail into a shield shape, flipping onto its back and displaying its colorful underside, all the way to.... Drooling! It's not well understood why they possess this behavior, and no one really knows if the "drool" contains any toxins, but it is by far one of the strangest occurrences to witness! Here is a larger individual moved off of a road shortly before night.
To be honest, you’re not exactly the best-looking newt I’ve ever seen. All the other newts have chocolate-colored backs and bright orange bellies and are cute as buttons. You’re rather pale and all wrinkly. But you were the only one I could find in the sunshine. Our spring has been slow in coming this year after above-average rain all winter, and the newt activity seems far less. So you’ll have to do.
One cool fact about you is that you have a toxin in your skin to protect yourself. It’s the same toxin used by pufferfish and can kill a person – if said person were foolish enough to attempt to eat you.
You were all by yourself on the sunny side of the creek, and when I immersed my little camera to get your picture, you took an interest. As a matter of fact, you became quite fascinated and started to follow it around! You seemed glad to have a friend who accompanied you as you meandered around the rocks. You were so cooperative it made me smile. We spent about 20 minutes together like that, and I came to realize that you truly are a super cute newt!
Be happy in the sunshine, wrinkles and all!

Centaurea maculosa, otherwise known as Knapweed, is an alien species in North America, commonly seen in wayside ditches. Its blooms vary in colour from white, to mauves, pinks and blues.
It is also suspected to be allelopathic, releasing a toxin from its roots that stunts the growth of nearby plants of other species.
This Varicose wart slug was on a mission. Fairly zooming across the sea bed. It's about 4 to 5 cm long.
Apparently all Wart slugs are masters of defence. when stressed they produce a pungent toxin. They have no known natural predators.
The Funeral Bell, (Galerina marginata).
The aptly named Funeral Bell contains the same toxins as the Death Cap so it is a good mushroom to get to know and then avoid.
It is a species of poisonous fungus in the family Hymenogastraceae of the order Agaricales.

Rather common species of butterfly in Hong Kong (except during winter).
The butterfly closely resembles the monarch butterfly (Danaus plexippus) of the Americas, and in fact both species are found within the same genus.
Similar to its American cousin, the Common Tiger sequesters toxins from plants it eats as a caterpillar, making it generally unpalatable for most predators.

Aquilegia (common names: granny's bonnet or columbine) is a genus of about 60-70 species of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals of their flowers. The genus name Aquilegia is derived from the Latin word for eagle (aquila), because the shape of the flower petals, which are said to resemble an eagle's claw. The common name "columbine" comes from the Latin for "dove", due to the resemblance of the inverted flower to five doves clustered together. The Colorado Blue Columbine (A. caerulea) is the official state flower of Colorado. Large numbers of hybrids are available for the garden, since the European A. vulgaris was hybridized with other European and North American varieties. Aquilegia species are very interfertile, and will self-sow. Some varieties are short-lived so are better treated as biennials. en.wikipedia.org/wiki/Aquilegia
The monarch butterfly or simply monarch is a milkweed butterfly in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. Wikipedia
Scientific name: Danaus plexippus
Order: Lepidoptera
What is so special about the monarch butterfly?
The bright patterned orange and black wings of monarchs advertise that they taste bad to predators. Monarchs retain toxins (known as cardiac glycosides) from the milkweed they eat as caterpillars (or larvae), making them poisonous to most vertebrates. Male and female monarchs are easy to tell apart.

'The Monarch larvae (caterpillar) feeds on the Milkweed plants which are toxic and stores the toxins in its body. When the butterfly emerges, it is poisonous to predators, such as birds.'
Did you know...blowfish contain a poison called tetrodotoxin, which is 1,200 times deadlier than cyanide. The toxin is so potent that a lethal dose is smaller than the head of a pin, and a single fish has enough poison to kill 30 people. Thought he'd be a fun addition to "Bright on Black". Taken in Tiki Iniki Restaurant in Princeville, Kauai.
It is still extremely cold here with temperatures going below zero every night. With the ground so hard and icy, the New Forest Ponies take to eating the gorse and holly bushes. Apparently, they are very clever: they bite off the tips of the gorse which contain relatively high levels of toxins and eat the still 'tender' but slightly older stems
Pterois volitans
El Pez Escorpión es una especie territorial y de hábitos nocturnos, permanciendo escondido casi inmóvil durante el día. En la noche se alimenta de pequeños peces, gambas y cangrejos a los que captura valiéndose de su amplia superficie torácica arrinconando a sus presas, aturdiéndolas con el veneno de sus espinas laterales y tragandolas después de un solo bocado.
¿Sabías que ...sus largas espinas dorsales y pectorales son venenosas y la picadura puede ser sumamente dolorosa?. La toxina que inocula puede causar parálisis respiratoria e insuficiencia circulatoria.

Fly Agaric (Amanita muscaria) is common especially where conifers grow. Out West this mushroom is often a bright red color, but in the East it’s typically orange/yellow. When certain gilled mushrooms, including many Amanita species, first form, they are encased in a membrane called a “universal veil.” As the mushroom enlarges and matures, the veil ruptures, with the dome transforming into a flattened cap.
Fly Agaric fungi got their name from the old European custom of placing little pieces of the mushroom in milk to attract flies. The flies supposedly become inebriated and crash into walls and die. This mushroom is somewhat poisonous (as are many Amanita species) and hallucinogenic when consumed by humans. The toxins affect the part of the brain that is responsible for fear, turning off the fear emotion. Vikings, who had a reputation for fierceness, are said to have ingested this mushroom prior to invading a village.
It is amazing to think that koalas survive purely on eucalyptus leaves.
For most animals eucalyptus leaves are extremely poisonous but koalas have evolved with the ability to flush the toxins out quickly.
This takes a huge amount of energy, hence why you will see koalas sleeping so much.

El marcòlic vermell o lliri morat (Lilium martagon) és una espècie de planta de la família de les liliàcies. També es diu consolta vermella. És endèmic a tota Euràsia, des dels Pirineus fins a Àsia Central i Corea. És una de les plantes que hom anomena lliris i consta de diverses subespècies.
Creix en boscs o prats, a muntanya. És bulbosa perenne que fa d'un a dos metres d'alt. Les flors, nombroses en cada planta, són normalment de color porpra rosat, amb taques fosques i són flairoses.
(Avís de la Wikipedia en anglès: aquesta flor és tòxica pels gats.)
ENGLISH
Lilium martagon, the martagon lily or Turk's cap lily, is a Eurasian species of lily. It has a widespread native region extending from Portugal east through Europe and Asia as far east as Mongolia.
Horticulturally it is in Division IX (true species). It is stem-rooting, growing between 1 metre (3 ft 3 in) and 2 metres (6 ft 7 in) tall. The flower colour is typically a pink-purple, with dark spots, but is quite variable, extending from near white to near black. The flowers are scented. Numerous flowers are borne on each plant, and up to 50 can be found on vigorous plants. The green stems can be flushed with purple or red and the leaves are elliptic to inverse lanceolate, mostly in whorls, up to 16 centimetres (6.3 in) long and often lightly hairy underneath.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Lilium martagon was used in hybridising with L. hansonii at the end of the 19th century by Mrs RO Backhouse of Hereford, England.
The name Turk's cap lily, also applied to a number of other species, comes from the characteristic reflexed shape of the petals. The specific epithet martagon is a Turkish word which also means turban or cap.
Lilium martagon, like many in the genus, is highly toxic to cats and ingestion often leads to fatal kidney failure; households and gardens which are visited by cats are strongly advised against keeping this plant or placing dried flowers where a cat may brush against them and become dusted with pollen which they then consume while cleaning. Suspected cases require urgent veterinary attention.Rapid treatment with activated charcoal and/or induced vomiting can reduce the amount of toxin absorbed (this is time-sensitive so in some cases vets may advise doing it at home), and large amounts of fluid by IV can reduce damage to kidneys to increase the chances of survival.

▶ "Phytolacca americana — also known as pokeweed, American pokeweed, dragonberries, and inkberry— is a poisonous, herbaceous perennial plant in the pokeweed family Phytolaccaceae growing up to 8 feet (2.4m) in height. It has simple leaves on green to red or purplish stems and a large white taproot. The flowers are green to white, followed by purple to almost black berries which are a food source for birds and some small animals (i.e., to species that are unaffected by its mammalian toxins). Pokeweed is native to eastern North America, the Midwest, and the Gulf Coast, with more scattered populations in the far West."

The rice paper butterfly, also called the paper kite butterfly, wood nymph, or tree nymph (Idea leuconoe) is a distinctive black and white butterfly. The wingspan is 95-110 mm across.
The larval wood nymphs are similar to monarch caterpillars in that they feed on plants in the Apocenaceae (dogbane) and Asclepiadaceae (milkweed) families. Also like the monarchs, giant wood nymphs are distasteful to predators. They derive this protection from the toxins produced by their host plants.
Wings of the Tropics, Fairchild Tropical Botanic Garden, Miami FL
Giant water bugs are fierce predators themselves, sometimes consuming prey larger than themselves. They inject a digestive toxin into their prey and suck out the liquified remains. (Yuck!)
Interestingly, it is the male that carries the fertilized eggs on its back until they hatch.
We have a pair of Black-headed Grosbeaks visiting this season. The female shown here is always a sweetheart at the feeder, politely standing by awaiting her turn.
(Nikon 300/2.8 + TC 2.0, 1/320 sec @ f/8, ISO 400)
Black-headed Grosbeaks' massive bills make them well equipped for cracking seeds, but those beaks are just as useful for snatching and crushing hard-bodied insects or snails. Insects (especially beetles), spiders, and other animals make up about 60% of their breeding-season food. Fruits and seeds make up most of the rest. Berries are a favored food during migration. Among wild fruit, juneberries, poison oak, and elderberries make common meals. Other regular foods include grains like oats and wheat, and weed seeds such as dock, pigweed, chickweed, and bur clover. They also feed on cultivated orchard fruit like figs, mulberries, cherries, apricots, plums, blackberries, and crabapples. In spring and summer, they feed at sunflower seed feeders and at nectar feeders set out for orioles. Where their range overlaps with wintering monarch butterflies, grosbeaks eat large numbers of these insects. Black-headed Grosbeaks don’t seem to suffer from the toxins concentrated in the monarchs’ bodies, which render them inedible to most birds.
A day flying moth (diurnal) species that can be found abundant throughout Europe from the Mediterranean to the northern shores of Scandinavia. This moth has a somewhat clumsy flight and is protected by strong toxins in the body which help to avoid its predators, hence the moths warning colours. Larvae will feed on Clover and Birds Foot Trefoil. Seen on the wing from June to August.
Why don’t you see them more often? The black-crowned night heron mainly feeds after dark. You are most likely to spot them at dusk and dawn along the edge of a waterway.
The black-crowned night heron was among many species declining nationwide between the 1940s and 1970s due to the cumulative effects of DDT and similar pesticides. Those environmental toxins were banned in the early 1970s.
While no longer considered at risk of a declining population, these herons are still affected by the accumulation of pollutants in the shellfish and fish they eat.
They are, however, one of the most wide-ranging of herons across North America. It is the larger of the two night heron species found in Florida.
With rare exceptions, the black-crowned night herons usually hover close to the water’s edge.
They commonly can be seen on mangrove roots, walking carefully along the edge of mud flats, and picking their way through cypress strands.
While they can be seen year-round in Florida, they can be found as far west as the Cascade Mountains of Oregon and Washington. They seasonally range into the central Canadian provinces and up the east coast all the way to Maine.
They feed in wetlands – freshwater, saltwater, and brackish – so that is the most likely place to find them.
I found this one just after sunrise along Peavine Road in Osceola County, Florida.

"In western North America, the sweet song of the Black-headed Grosbeak caroling down from the treetops sounds like a tipsy robin welcoming spring. The flashy black, white, and cinnamon males and the less flamboyant females sing from perches in suburbs, desert thickets, and mountain forests... In central Mexico, where monarch butterflies and Black-headed Grosbeaks both spend the winter, the grosbeaks are one of the butterflies' few predators. Toxins in the monarch make them poisonous to most birds, but Black-headed Grosbeaks and a few others can eat them. They feed on monarchs in roughly 8-day cycles, apparently to give themselves time to eliminate the toxins." - Cornell University Lab of Ornithology
Giant Hog Weed (Heracleum mantegazzianum)
perennial plant and a member of the carrot family
Seeds may take several years to germinate and are viable in the soil for up to 15 years. During the first year, the plant produces a rosette of leaves up to one meter high. After 2 to 5 years the plant produces flowers. As it grows a large root, thick hollow stems and large lobed leaves are formed. The stems of the plant are covered with reddish-purple flecks and stiff hairs filled with sap. Sap may also collect in the hollow stem bases. Giant hogweed flowers once in its lifetime, Once the plant produces seeds it dies. Each plant can produce up to 120,000 winged seeds (typically 50,000). Seeds dropped in streams can float for three days. They can move long distances via water in ditches and streams. Seeds can also be spread up to 10 meters by the wind.
Health Concerns
The clear watery sap of giant hogweed contains toxins that can cause severe dermatitis (inflammation of the skin). You can get severe burns if you get the sap on your skin and the skin is then exposed to sunlight. Symptoms occur within 48 hours and consist of painful blisters. Purplish scars may form that last for many years. Eye contact with the sap has been reported (in the media and by various web sites) to cause temporary or permanent blindness. However, evidence of permanent blindness linked to exposure to giant hogweed cannot be substantiated by any existing research. Coming in contact with cow parsnip and wild parsnip can cause similar reactions.
Spyhopping is an act of coming out of the water vertically and staying above the surface momentarily, in the same way, a human treads water. An extremely powerful Orca can be spy-hopping for longer periods of time and get as much as half of its body above the surface of the water. This is a young Orca from A pod, the young whales have a visible orange tint due to toxins the Mother whale accumulates over time then passes on to the young during gestation.
This species of frog lives in the Amazon on the border between Suriname and Brazil. It has a blue skin that warns predators of their toxicity. On their skin tissue there are glands that secrete a toxin that paralyzes and can kill the predator. The poison molecules are produced thanks to their diet of particular ants, beetles and millipedes. The ones kept in captivity, fed on crickets and midges, keep the blue warning color, but are not venomous. The Amazonian Indios know the poison of frogs and use it to dip the tips of their arrows.
Photographed the white flower blossoms of the Pin Cherry Tree found on Prout's Island on Lake Sesekinika located in the Township of Grenfell in Northeastern Ontario Canada
Pin Cherry trees produce small, edible fruits, that are sour when raw, but make excellent preserves. However, all non-fruit parts of the tree contain toxins and are inedible. Pin Cherry grows quickly, and can also spread through suckers, making it useful for stabilizing eroding soils and riverbanks. Pin Cherry like open woodlands, and will readily colonize recently disturbed stands, helping to begin the reforestation process. These small trees only live about 40 years, but they produce a lot of fruit once mature, which many animals rely on in late summer. Pin Cherry fruits are so popular with songbirds that this tree is commonly known as Bird Cherry! Source: The Arboretum Uof G.

A lot of ladybugs produce toxins that make them distasteful to birds and other would-be predators. These noxious substances are linked to a ladybug’s color; the brighter the ladybug, the stronger the toxins.
a dangerous train ...
The pine processionary (Thaumetopoea pityocampa) is a moth of the subfamily Thaumetopoeinae in the family Notodontidae, known for the irritating hairs of its caterpillars, their processions, and the economic damage they cause in coniferous forests.
Toxicity :
Stinging hairs contain a toxic protein that is very irritating and inflammatory: thaumetopoein. It penetrates where the “harpoon” is planted: most often in the skin, but also in the eye, the nose, the mouth…
The hair breaks and the toxin released causes a reaction similar to that of nettle stings: red pimples in the form of blisters, red itchy patches, appear on the skin.
General symptoms may occur in the event of significant exposure. The immune system then goes into overdrive, which can lead to a sudden drop in blood pressure, discomfort or loss of consciousness.
Is there a risk for animals? With their noses at ground level, animals are exposed to contact with these stinging hairs, particularly dogs. They can get it on their coat, or even take a caterpillar in their mouth, which can cause very serious inflammatory reactions including necrosis of the tongue.
Un train dangereux ...
La processionnaire du pin (Thaumetopoea pityocampa) est un papillon de nuit de la sous-famille des Thaumetopoeinae de la famille des Notodontidae, connue pour les poils irritants de ses chenilles, leurs cortèges et les dégâts économiques qu'elles provoquent dans les forêts de conifères.
Toxicité
Les poils urticants contiennent une protéine toxique très irritante et inflammatoire : la thaumétopoéine. Elle pénètre là où le « harpon » s’est planté : le plus souvent dans la peau , mais aussi dans l’œil, le nez, la bouche…
Le poil se casse et la toxine libérée provoque une réaction semblable à celle des piqûres d’ortie : des boutons rouges sous forme de cloques, des plaques rouges qui grattent, apparaissent sur la peau.
Des symptômes généraux peuvent survenir en cas d’exposition importante. Le système immunitaire s’emballe alors, pouvant mener à une baisse brutale de la tension artérielle, un malaise ou une perte de connaissance.
Y a-t-il un risque pour les animaux ? La truffe au ras du sol, les animaux sont exposés au contact avec ces poils urticants, notamment les chiens. Ils peuvent en avoir sur le pelage, voire prendre une chenille dans leur gueule, ce qui peut provoquer des réactions inflammatoires très graves jusqu’à une nécrose de la langue.

Both adults and nymphs damage squash and pumpkin plants by sucking juices out of the leaves. The leaves then lose nutrients and water, become speckled, then yellow, then brown, and finally, the plant totally wilts and dies. The squash bug also injects a toxin that expedites the plant's withering and death. I barely have them under control. Controlling them takes daily examination of the underside of leaves and stems and removal of eggs, nymphs and adults.

Muchos católicos creen que con que a menudo hagamos buenas obras, ayudemos a los pobres, apoyemos a los débiles, participemos en trabajos voluntarios y demos limosna, etc., cuanto más hagamos por estos métodos, más nos aprobará el Señor, al final podremos entrar en el reino de los cielos.
Pero aunque tenemos buenas acciones en el exterior, aún no podemos evitar pecar y confesar y estamos atados y controlados por el pecado sin ser capaces de escapar de él. El Señor dice: “[…] Santos seréis, pues, porque yo soy santo” (Levítico 11:45).
“Antes de que el hombre fuera redimido, muchos de los venenos de Satanás ya habían sido plantados en su interior, y, después de miles de años de ser corrompido por Satanás, el hombre ya tiene dentro de sí una naturaleza establecida que se resiste a Dios. Por tanto, cuando el hombre ha sido redimido, no se trata más que de un caso de redención en el que se le ha comprado por un alto precio, pero la naturaleza venenosa que existe en su interior no se ha eliminado. El hombre que está tan contaminado debe pasar por un cambio antes de volverse digno de servir a Dios”.
Extracto de “La Palabra manifestada en carne”
Dios es santo, pero estamos llenos de toxinas satánicas dentro de nosotros, bajo el control de ellas, todavía podemos odiar y envidiar a otros, también mentir y engañar a los demás y a Dios por intereses, buscar la vanidad y seguir las tendencias del mundo, y así sucesivamente. Estamos llenos de inmundicia y no hemos alcanzado la purificación, así que no estamos calificados para entrar en el reino del Señor. Entonces, ¿qué debemos hacer para lograr la purificación del pecado y entrar en el reino de los cielos?

It is strange to think that such a beautiful plant as the Foxglove could be so toxic. Yet Foxglove plants have earned several sinister sounding names such as Dead Man's Bells and Witch's Gloves.
Depending on the species, the digitalis plant may contain several deadly physiological and chemically related cardiac and steroidal glycosides. The toxins can be absorbed by simply touching them or ingesting them.
A bee joins a Zebra Butterfly feasting on a Passion Fruit flower.
From Bug of the Week -
I had the opportunity to enjoy the antics of the remarkable zebra longwing, Heliconius charitonius, as it visited flowering trees and shrubs along a trail through a swampy forest. Tropical butterflies in the genus Heliconius, such as the zebra, are notable for their longevity. These beauties live up to six months. Zebras and their kin evolved an interesting strategy to gather nutritious pollen used to sustain their long lives. The zebra flies a well-defined route through the forest visiting flowers that present a fresh batch of pollen and nectar each day. This behavior is called traplining and is employed by many tropical pollinators including bees, hummingbirds, and bats.
After collecting a gob of pollen on its long, straw-like proboscis, the butterfly secretes specialized enzymes to release the amino acids and other nutrients in the pollen. The nutrients are absorbed through the membranes lining the proboscis and used to produce eggs and maintain the zebra’s high level of activity zooming about the forest. In addition to visiting flowers laden with pollen, the zebra also searches for different species of plants in the passion vine genus, Passiflora.
These tropical vines bear the magnificent passion flower and following pollination, the passion fruit. Several species of passion vine are used by the immature stages of the zebra and other Heliconius butterflies as a source of food. These voracious caterpillars consume great quantities of leafy tissue on a daily basis. As a group, passion fruit plants are protected from most leaf-munching caterpillars and other vegan insects by a veritable witch’s brew of highly toxic chemicals including alkaloids, a family of toxins that include strychnine and nicotine, and cyanogenic glycosides, chemicals that release cyanide upon entering the body. However, using some clever metabolic machinery, the specialized Heliconius butterflies have turned the tables on passion fruit plants and now feast on their leaves with impunity. With so much munching by the larvae of the zebras and their kin, one wonders how the vines of Passiflora survive.
From the butterfly breeder/photographer - the passion fruit vines act as a 'host' for the zebra butterflies. I have many of those as well as Firebush which the butterfly enjoys. Adult zebra longwing butterflies feed on both flower nectar and pollen. The additional nutrients from the pollen enable individuals to survive for several months, far exceeding the normal two to four week adult life span of most other butterflies. Adult individuals often form small communal roosts at night. Sometimes they swarm around me - the first time they did that I was shocked.
Yes I was out in a preserve looking for a zebra on a passionflower when I took this photo - the bee was an 'extra'.
BTW - since this was photographed with an R7 - this telephoto shot (hand-held) was at over 500mm.
From the Florida Times Union :
...you’ve probably seen the flight of the distinctive black butterfly with bold yellow stripes, the zebra longwing butterfly (Heliconius charithonis). Since 1996, it has been the Florida state butterfly. What you discovered is the mature larvae feeding on its host plant, one of many species of passionflower.
You really can’t confuse it with any other Florida butterfly. This impressive 2 1/2- to 4-inch flyer with its striking pattern prefers warm, damp, tropical hammocks and thickets. Just the conditions most of the state provides, especially central and south Florida.
L'Oie-armée de Gambie (Plectropterus gambensis), également appelée plectroptère de Gambie ou plus simplement l'Oie de Gambie, est une espèce d'oiseaux aquatiques de la famille des Anatidés. Elle est apparentée aux tadornes. C'est la seule espèce du genre Plectropterus.
Lorsqu'au Nord Bénin, l’Oie-armée de Gambie consomme certains coléoptères de la famille des Méloidés, elle accumule dans ses tissus une toxine : la cantharidine, (substance notamment présente chez l'insecte cantharide officinale (Lytta vesicatoria), surnommée la mouche espagnole ou mouche de Milan, principal composant de préparations anciennes réputées aphrodisiaques) qui peut occasionner chez les prédateurs des cystites ou priapismes douloureux.

"In western North America, the sweet song of the Black-headed Grosbeak caroling down from the treetops sounds like a tipsy robin welcoming spring. The flashy black, white, and cinnamon males and the less flamboyant females sing from perches in suburbs, desert thickets, and mountain forests... In central Mexico, where monarch butterflies and Black-headed Grosbeaks both spend the winter, the grosbeaks are one of the butterflies' few predators. Toxins in the monarch make them poisonous to most birds, but Black-headed Grosbeaks and a few others can eat them. They feed on monarchs in roughly 8-day cycles, apparently to give themselves time to eliminate the toxins." - Cornell University Lab of Ornithology

The common name "castor oil" probably comes from its use as a replacement for castoreum, a perfume base made from the dried perineal glands of the beaver (castor in Latin). It has another common name, palm of Christ, or Palma Christi, that derives from castor oil's reputed ability to heal wounds and cure ailments.
The leaves are large, palmately lobed, have 8 points, are slightly serrated and have very large central veins. The seeds are contained in prickly or smooth three membered capsules, also known as the fruit. Each capsule contains their own seed. Seed size is known to be between 450 to 5,000 seeds per pound. In the commercial industry they are more commonly 1,000 to 1,500 seeds per pound. Seed color varies from plant to plant and can be white, gray, yellow, brown, red or black. The seed itself also has a pattern on it that can be brown, black or gray and they can be splotchy or fine spots. Each seed contains between 40% and 60% oil that has triglycerides, specifically ricinolein. The colors of the leaves can be green or a brownish red. The flowers are typically green but other varieties have different colors such as red and pink. The plant’s stamens tend to stay near the bottom and the pistils (female reproductive part of flower) near the top. There are no petals on the plant and the female flower, which lie above the male flowers, consist of a little spiny ovary which develops into the fruit or seed capsule.
The inside of the castor bean itself is very unique. Unlike a lot of other seeds the castor bean doesn't have an apical meristem below the cotyledons. The apical meristem is the foundation for all tissues in a plant. The cotyledons, after fertilization, can turn into the first leafs of the plant.
Ricin: The castor beans deadly toxin!
The castor bean also includes a deadly toxin called ricin. When ricin enters the body it prevents the cells from producing the proteins they need. Without these specific proteins the cells cannot function and they die. If this cell death is wide spread enough it can lead to the organism dying.
The toxin is released when the beans are chewed or crushed. If the beans are ingested it can lead to pain of the skin and eyes, profuse vomiting, diarrhea, severe dehydration, weakness, fever, myalgia, arthralgia, hallucinations, seizures, hematuria, hypotension, hypovolemic shock, multiply system organ failure and death!! It is said that three seeds contain enough ricin to kill a child and that 7 seeds can kill an adult.
Between November of 1969 and January of 1970 about 10,000 ducks died in Texas. Autopsies of the ducks revealed castor beans in their stomachs. The castor oil plant has been known to contribute to large numbers of casualties annually.

Aquilegia (common names: granny's bonnet or columbine) is a genus of about 60-70 species of perennial plants that are found in meadows, woodlands, and at higher altitudes throughout the Northern Hemisphere, known for the spurred petals of their flowers. The genus name Aquilegia is derived from the Latin word for eagle (aquila), because the shape of the flower petals, which are said to resemble an eagle's claw. The common name "columbine" comes from the Latin for "dove", due to the resemblance of the inverted flower to five doves clustered together. The Colorado Blue Columbine (A. caerulea) is the official state flower of Colorado. Large numbers of hybrids are available for the garden, since the European A. vulgaris was hybridized with other European and North American varieties. Aquilegia species are very interfertile, and will self-sow. Some varieties are short-lived so are better treated as biennials.
Ranunculus bulbosus, commonly known as bulbous buttercup or St. Anthony's turnip, is a perennial flowering plant in the buttercup family Ranunculaceae. It has bright yellow flowers, and deeply divided, three-lobed long-petioled basal leaves.
Other names for the bulbous buttercup are "Goldcup" because of the colour and shape of the leaves, and "Frogs-foot" from their form.
This plant, like other buttercups, contains the toxic glycoside ranunculin. It is avoided by livestock when fresh, but when the plant dries the toxin is lost, so hay containing the plant is safe for animal consumption.
I have stood on both banks of the Kings River coming into Kings Canyon National Park; I have stood on the one place where I could plant a foot at an Alpine lake in Mt. Rainier; I have gotten down on my knees (in days of yore when they bent) at the bank of the Merced River Tuolome Meadow and again in Tuolume Meadows both in Yosemite, each time to get one decent image of a Columbine. Red. Yellow. It didn't matter. (The image below was my first success and that's a long time ago.)
This morning, after attempting to capture this Serpentine Columbine between swaying branches from bushes, and deep shade under a huge oak that allows little sun, I took this shot. This was at least my fiftieth attempt. The EXIF tells part of the story. Certainly the low ISO helped with clarity or sharpness. I must say that the plants that I've encountered at Bancroft Garden, mostly "dry plants" (i.e., plants that live in arid and semi arid conditions), have deeper colors than any wildflowers I've encountered in the wild. (These are wildflowers because they're not cultivars, but because I can visit almost daily, I stand a better chance than hiking into the hills and finding a flower that stands out from its surroundings.)
If I were to name this particular Columbine, I would have named it The Crown Columbine. But no one asked or ever will.
It is seems to have been a good year for cinnabar moth caterpillars. They can be found in their hundreds munching away on yellow-flowered ragwort, and their bold black-and-gold stripes make them easy to identify.
They are the cinnabar caterpillar’s main food plant and ragwort supports many other insect species and is also an important source of nectar. It is toxic and known to poison horses and other livestock if eaten, particularly via contaminated hay. The toxins within the growing plant make it so bitter and unpalatable that it is usually avoided but the cinnabar caterpillars feast upon ragwort without ill effect. They benefit from its toxicity and eat enough of it to become toxic themselves with their colourful stripes a warning to predators: I’m poisonous and taste terrible, don’t try to eat me!
It takes about a month for them to develop fully, at which point they will descend to ground level ready to pupate. They will remain here all winter, safe inside their cocoons, and complete their metamorphosis the following spring to emerge as beautiful black and red adults. They are brightly coloured for the same reason as the caterpillars, since the ragwort’s toxins remain in their bodies and still provide an effective defence against predators.
I posted a shot of the adult moth about six weeks ago so just check in my photostream

Arothron stellatus is a medium-sized fish which grows up to 120 cm (47 in) in length. Its body is oval shaped, spherical and relatively elongated. The skin is not covered with scales but is prickly. The fish has no pelvic fin and no lateral line. The dorsal fin and the anal fin are small, symmetric, and located at the rear end of the body. The head is large with a short snout that has two pairs of nostrils, and the mouth is terminal with four strong teeth.
The background coloration goes from white to grey, and the body is harmoniously dotted with black spots. The ventral area is usually clearer. The size of the spots is inversely proportional to the size of the fish; thus, a young individual will have large spots and adults of maximal size will have small spots. The juveniles have a yellowish body background coloration with dark stripes. The young adults still have stripes on the ventral area that will turn to spots later, and also some recollection of yellow on the body. Arothron stellatus feeds on benthic invertebrates, sponges, algae, the polyps of corals such as Acropora, crustaceans and mollusks.
This pufferfish is diurnal. It is mainly solitary and defends a territory. Arothron stellatus contains a highly toxic poison, tetrodotoxin, in its ovaries and to a lesser extent its skin and liver, which protects it from voracious predators. It becomes toxic as it eats bacteria that contain the toxin. To ward off potential enemies, they can inflate their bodies by swallowing air or water. (Wikipedia)
