The gill of Doriopsis

March 7, 2003
From: Bill Rudman

Here are some photos to show the gill in Doriopsis granulosa. Species of Doriopsis differ from most dorids in having the gills arranged in a posteriorly facing, horizontal fan. There is a flap of mantle which hangs over, and protects the gill opening. See D. pecten Fact Sheet for a similar photo of its gill. Another name for the genus is 'Ctenodoris' which is from the Latin word for a comb, which refers to the comb-like appearance of the gills. The name pecten also is derived from the same Latin word.
