Costasiella ocellifera from Dominican Republic

April 30, 2003
From: Elianny Dominguez

Dear Bill,

I found this nudibranch on Udotea sp, at 44 ft. in the Dominican Republic. It is 5 mm long, and 2 mm width. Its tail was very long - almost half the body length

Any idea?

Dear Eli,
You are lucky your photo caught the two good external features of this species - the eyes very close together mean it is a species of Costasiella, and the orange-yellow ring just behind them identify it as Costasiella ocellifera. The orange ring is supposed to surround a black-ringed blue spot, but I am sure your animal is just a variation of this. I assume the 'DR' in your message meant Dominican Republic? Some fuller locality data would be useful. I'm afraid I can't see enough in your other photo to have any idea what it is
Best wishes,
Bill Rudman
