Cyerce nigricans from Heron Island

July 14, 1999
From: Julie Marshall


Hi Bill,

A couple of weeks ago you asked for some other photos of Cyerce nigricans. This is a photo of an animal found intertidally in the mid reef area at Heron Island [Great Barrier Reef] and and also one of an egg mass found on a different occasion in September 1994. This egg mass was one of number found under a dead coral slab at the reef crest together with three animals. I have found Cyerce nigricans a number of times at Heron Island, usually intertidally, either on or close to its food, the green alga, Chlorodesmis fastigiata.

Best wishes

Dear Julie,
Thanks for the photos. With help from you and Clay Carlson we now have some nice photos of Cyerce nigricans. I'm glad you had the egg mass photo, as these flattened spirals are a good sign that a sacoglossan is around. However although most dorids ahve the egg ribbon attached along one edge, there are a few dorids such as Chromodoris striatella which have egg ribbons like this lying flat on the substrate.
Best wishes,
Bill Rudman.
