Aeolids from Bahia de Banderas

April 26, 2002
From: Alicia Hermosillo

Dear Dr. Rudman,
As of now, I have 12 unidentified aeolids, 1 dorid and 1 dendronotacean in my survey.

I am sending you pictures of one of them. I found it 17 feet deep in Playa Mismaloya, Bahia de Banderas, Pacific Coast of Mexico on April 6th. It was 7 mm long and next to another smaller one 5 mm long.

Can you identify it? I will be sending you pictures of my other difficult ones to see if anyone around can help me out.
Thanks and best regards

Dear Ali,
The rounded anterior corners to the foot suggest it may be a species of Cuthona, but we will need some local expertise, or a look at its anatomy, to have much idea about its identity. With luck the "East Pacific - unidentified page won't get too large.
Best wishes,
Bill Rudman


Cuthona sp. 9
