CA SEA OTTERS: Santa Cruz
Animal Classification
Sea Otter (Enhydra lutris)
Description
Sea otters are members of the weasel or mustelid family. Like other members of this family, they have very thick fur. In fact, at 850,000 to one million hairs per square inch, they have the thickest fur of any mammal. Their fur actually consists of two layers, an undercoat and longer guard hairs. This system traps a layer of air next to their skin so their skin does not get wet. Sea otters are usually dark brown, often with lighter guard hairs. Alaskan sea otters tend to have lighter fur on their heads. Sea otters are the smallest marine mammals. In California adult females weigh 35-60 pounds (16-27 kg); males reach up to 90 pounds (40 kg). Alaskan sea otters are bigger with males weighing up to 100 pounds (45 kg).
Range/Habitat
Sea otters once ranged from Mexico to Alaska and even to Japan. Currently, the California population numbers around 2,800 and is found from Half Moon Bay to Morro Bay. There is a much larger population in Alaska, and sea otters are still found in Russia. Sea otters inhabit shallow coastal areas and prefer places with kelp. The kelp acts as an anchor that the sea otters use to wrap themselves in when they are resting.
Mating/Breeding
Females give birth to one pup and usually have their first pup at the age of four or five. Their pregnancies last four to five months. Pups can be born any time of year, but in California most are born between January and March, and in Alaska most are born in the summer. When born, the pups weigh from three to five pounds.
Behavior
Sea otters are social animals, with females and pups spending time together in one group and males in another. Pups stay with their mothers for the first eight months of their life. The pups' fur traps so much air that they actually cannot dive under water. When mothers leave the pups wrapped in kelp to hunt, pups bob on the surface of the ocean like a cork. Mothers spend much time grooming pups and often carry them on their chests. Pups begin to learn to swim at around four weeks of age. Sea otters are one of the few animals to use tools. They eat animals with shells, like clams and abalone, and use a stone to break open the shells. When sea otters are under water searching for food, they store what they have found in the loose skin folds at their armpits. Adult sea otters can eat 25%-30% of their body weight in one day!
Status
Sea otters in California are a threatened species due to past over hunting for their beautiful fur. Although sea otters are protected now, they remain vulnerable, especially to oil spills. Unlike other marine mammals, sea otters do not have a blubber layer. Therefore, they rely on their fur to keep warm. If their fur is oiled, it loses its insulating qualities and the sea otters soon chill. Otters are also affected by the oil fumes or poisoned by eating food exposed to oil. Most sea otters quickly die in an oil spill. Several thousand sea otters died in the 1989 Exxon oil spill in Valdez, Alaska. Other threats to sea otters include infectious diseases, parasites, boat strikes, entanglements, and toxins.
At The Marine Mammal Center
The Marine Mammal Center began rehabilitating sea otters in 1995. Since that time, we have rescued up to 207 sea otters.

Lovin' MB 'till the day I die!!!!Lov fam,friends,and haterz even though they say some mean sh!t 2 me.I do wat i do 2 survive in this world and aint nobody gonna stop mii from doin wat i lov,which iz makin lotz of friends.PRAY EVERY DAY AND BELIEVE IN YOSELF!!!!!!!!!!
Anita Li (M.S. ABA '13) from Florida is about to get a participant for one of the operant chamber experiments. An operant chamber is a container in which an animal is placed that has various manipulanda (like levers, or in our case, IR hoops) that are linked to some consequence (food, water, lights, etc). They are used to study learning.
Primary School students were rewarded for all their positive behavior with a special event with Luau Relay Races.
This is the Tatty Old Girl (right bottom) and (I think) The Pale Golden Youngster. The Old Girl buzzed the youngster from its perch (unfortunately behind an intervening tree from my camera) and they made passes at one another quite low to the ground with a couple of goes at talon locking (which I missed with the camera) before they went up quite steeply soaring high above. I don't think it was mating behaviour? The Tatty Old Girl is easily identified because almost half her tail feathers are missing and a flight feather from each wing. I have been seeing her with groups of youngsters for the last year and a half, and I feel her role is sort of teacher/protector ... and I think the Pale-golden Youngster cops a lot of teaching from the adults ... but, hey! how would I know anything for sure?
When I got home from bird-watching yesterday, I found this little tree toad cuddled up next to the charger for my mobility scooter. When I pulled the cord out of the hole where I store it , I apparently shocked (only in the sense of "surprised") the toad despite its unperturbed appearance. He jumped down the hole like those suicidal lemmings one reads about. It looked like the hole extended down about five feet to a cement floor. Later, though, I got a flashlight and peered down the hole and was glad to see a blockage less than a foot below the opening, However, there was no little toad. I guess he managed to use his sticky little feet to make his escape. Strangely, though I saw him cuddling next to the charger again this morning.
Thank you for your visit.
Even a kitty-plush ignores you. :P
This was given to me as a gift after I found out that my cat, Hannah Jane, died after medical complications from the vet.
Our father's friend, Dick, came upon a 1929 Model A Ford for sale and convinced my dad they should buy it together. It was split between households as a fun, occasional driver. To say you stood out while tooling down any street is an understatement. In case everyone didn't turn their heads to notice, you could just hit the horn (ah-OOOO-ga!) a few times to guarantee smiles. We five kids sat upon the running board for the snapshot above. Was it Easter? Because I don't think those were our usual church clothes!
Discharge is a continuous sound sculpture exploring the behavior of an electronic circuit on a component level. A piece in the Discharge series is an iteration of the circuit conceived in June, 2009. The circuit outputs a harmony of distorted triangle waves tuned to the ambient light of its environment. For this exhibition at St. Cecilia’s convent, I wanted to present the circuit itself as the composition. Discharge happens when a human touches certain wires and becomes a living part of the circuit. Upon making skin contact, electricity is discharged from the capacitor into the human participant, and, as energy leaves the circuit, its corresponding oscillator swells into "view", taking prevalence above the others in the audio path as the filter opens. When fingers are lifted, the capacitor begins to charge, and as the filter closes, the tone slowly fades back to its original state.
However, when I attempted to install this piece here, I found that when I touched the circuit, radio sounds blasted through the amplifiers. Upon closer listening, I realized that the circuit was picking up the Disney Channel at extremely high volumes. This had not once happened since the circuit’s creation. In a panic, I began to try anything that would fix the problem. In my research I discovered that Disney, through huge subsidies to the government, broadcasts their signal through the power lines, modulated at 60 hz to allow for easy transmission anywhere. This fact is so disturbing, I can hardly believe it. How could Disney have access to the entire grid? This old building is wired in an old-fashioned electrical standard—because no conduit tubing is used, the whole building is seething with radio frequencies. Upon touching the circuit in St. Cecilia’s Convent, a human becomes an antennae for Disney radio, and their signal overrides Discharge as it pours through the speakers. I tried wrapping the walls and the radiator in layers of aluminum foil, but to no avail. I even used a battery powered amplifier, but Mickey’s frequencies creep in nonetheless.
I’ve decided to show Discharge in its incomplete state—without the possibility of human touch—as an act of protest against the Disney Corporation. Such high-wattage broadcasting dwarfs any sort of local network. Government sanctioned access to the electrical grid is borderline tyranny. If I jammed these radio frequencies in order to present the piece, I would be committing a federal crime (Legality aside, it might not even be possible to jam Disney radio, as their signal is so strong and omnipresent in this region). For me, the problem is not content, but presence. A slight shift in content (or perspective) could turn Disney’s broadcast from innocuous to nefarious. In the sound & light environment, you will hear a mass of waves generating and responding to light, and the sounds of Disney radio creeping into the sound system.
