Note added 26 March 2002: See Kathe Jensen's message suggesting there are probably two species in this message.
Ercolania coerulea was mentioned recently in a message from Kathe Jensen, and I am attaching some photos of this species from Abaco, Bahamas. Small examples of this species - (from 2 to 5 mm) - occur in Abaco on a variety of algae, including Caulerpa racemosa, C. verticillata, Cladosiphon occidentalis, Cladophora and Dictyosphaeria cavernosa. The only large specimens that I've found have been on Dictyosphaeria.
