Limacia cockerelli  
Cockerell's nudibranch 

Synonym: Laila cockerelli 

Limacia cockerelli is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Polyceridae. This species is found from the West coast of North America ranging from Vancouver Island, British Columbia, Canada to Baja California. It has also been found in the Gulf of California at Bahía de los Ángeles. 

It is found in two forms. The northern form has white tubercles down the middle of the dorsum. The second form, found in areas south of Point Conception have tubercles that are slightly longer and tipped with orange. Intermediate forms exist in central and northern California. Another form in California has large red blotches on the dorsum. The eggs of the Limacia cockerelli are pink and develop after 17 days, (at 10-13 degrees C), into hatching planktotrophic veligers.

This animal preys exclusively on the orange-brown colored bryozoans, Hincksina velata and Membranopora.

On my first trip to Costa Rica, in 1994, I found this injured White Faced Capuchin on the side of a path through Cahuita National Park.  He was covered with bite and slash marks, likely the result of a lost battle for dominance in his troop, and was shaking. He looked like he was in shock.  He was so fearful that he bared his fangs at me and screeched, but he made no actual attempt to get away as I picked him up.  I wrapped him in shirt and cradled him... he showed me his fangs a couple times, then he quickly settled down and soon began to doze off like a small child.  

The local ranger station didn't know what to do with him, and directed me to a vet in the next town up the highway.  The vet was very helpful and agreed to take the monkey, and forward him to a wildlife rehab center.
