Unknown Nudibranch

December 12, 2000
From: Marc Elig


I recently added some live rock and discovered a Nudibranch in my sump today. From the descriptions given in "The Reef Aquarium" Vol 1, it appears to be suborder Aeolidacea. It is peach colored, has the rhinophores and oral tentacles that look like two hands laid flat palms down with thumbs and index fingers touching. It has cerata running down both sides of the body that are like hoops of yarn. Does anyone recognize this picture:

I'd like to know what it eats. I've got it in my quarantine tank, until I can verify if it's safe. I'd like to keep it alive if possible, but I understand that they are usually very specific eaters. I just started the webpage above to show this picture. Sorry the enlargement link didn't work. Soon I'll put my tank pictures on the web page. Thanks for any help.

Dear Marc,
Your animal is a tritoniid rather than an aeolid, and like most of its relatives it feeds on soft corals. If you look at the decription above your message and the information in the other messages below yours, you will find further information about feeding in this species, Tritoniopsis elegans.
Best wishes,
Bill Rudman
