Chromodoris baumanni from Bahia de Banderas

Dear Dr. Rudman,
I am sending you pictures of Chromodoris baumanni from Bahia de Banderas, from Playa Lindomar, [Mexico, Pacific coast] taken on July 21st 2003 (with sponge) and February 23rd 2003 (group photo). Depth around 20 feet, animal lengths between 15 and 28 mm, night dives.

I have observed Chromodoris baumanni in Bahia de Banderas to be a nocturnal critter, found very rarely crawling around during the day.

This particular spot seems to hold the greater abundance of the species. The animal in the picture was feeding on this orange sponge, sorry, I do not know the species, but it is more abundant here than anywhere else in the Bay. The upper picture was a very nice and uncommon occurrence of 4 together.

Thanks Ali,
Your contributions are certainly improving our knowledge of the eastern Pacific fauna
Best wishes,
Bill Rudman
