Chromodoris norrisi from Mexico

From: Alicia Hermosillo

Dear Dr. Rudman,
I have found recently 2 other species of chromodorids with orange spots and patterns. This Chromodoris norrisi I found on May 5th, under a rock, 31 feet deep in Islas Marietas, north of Bahia de Banderas, Pacific Coast of Mexico. It was 11mm long.

The other orange spotted species is Tyrinna evelinae which I have found both under and on top of rocks all through out the Bay (from the northern Marietas Islands to the south at Chimo).

Thanks Ali,
I am glad I can still be amazed at the brilliant colours of some nudibranchs. You must be pleased that some of the 'missing' species are turning up for you. I look forward to some photos of Tyrinna evelinae.
Best wishes,
Bill Rudman
