Hypselodoris bayeri from Belize

September 27, 2002
From: Dave Behrens

Dear Bill:
Thank you for posting Eveline's photo of H. bayeri. This species has always bothered me. Here is a specimen I collected in the mangroves at Lark Cay, Belize, several years ago. For some time we considered it an undescribed species, but now have come around to the opinion it is the Marcus' Hypselodoris bayeri. The photograph was taken by Jeff Hamann. Since that time I have collected it in Honduras, also.

Comparing Eveline's photo with the photo in Humann's Reef Creatures Guide and this photo, we have a better feel for the variation and consistencies in mantle coloration. Concerning its similarity to Hypselodoris acriba, I have collected it from the same region, and believe the two species to be distinct.

p.s. Please note that is a parasitic copepod on edge of mantle, not an aberration.
Thanks again.

Thanks Dave,
The black spots around the edge of the mantle in Jeff Hamann's photo are certainly more as described by the Marcus's than in the photo I posted, and the rhinophores in Jeff's photo show only a hint of the spectacular blue of the other photo. I hesitated about posting the Marcus' photos, as I didn't know who the photographers were, and there was little accompanying data, so I am glad you have found them useful.
Cheers,
Bill Rudman
