Pleurobranchus atlanticus from Netherlands Antilles

September 18, 2002
From: Linda Ianniello

Dr. Bill,
I think this is a Pleurobranchus areolatus based on the description found in Paul Humann's book. His picture is of a much darker specimen but the text indicates it can also be fairly light-colored. You can barely see the two layers along the side, where the gills would be.

Location: 'Saba, Netherlands Antilles' dive site called Tent Wall
Depth: Approximately 40 feet
Length: About 2 inches
Date: July, 2002

I found this guy at the top of the reef, in a location with nothing but sand. When I first saw him, he had his head stuck in a small hole.

Dear Linda,
There is considerable confusion over the Caribbean pleurobranchs. Have a look at my my reply to Anne DuPont's message where I suggest this is really Pleurobranchus atlanticus.
Best wishes,
Bill Rudman
