Re: Elysia sp. 7 from Texas

Dear Bill,

Flipping through the unidentified Elysias on your species list, I came across your Elysia sp 7 which was posted while I was in the process of moving to Thailand. This species I am almost certain is Elysia chlorotica. The photographs do not show many details, but the drawing excellently shows the broad foot with tentacular processes, the relatively thin rhinophores, the short pericardium, and the numerous dorsal vessels leaving an "empty" space behind the pericardium. The species is also one of the few that can tolerate low salinity. It normally occurs along the coast of NE America, including Canada, but occasionally reaches down to Florida in the winter. This may explain how it reached this place along the intracoastal waterway; my suggestion is that the animals had been hiding on a boat and got dumped along the way. It feeds on a soft, fine filamentous alga, Vaucheria, which forms slippery dark green, almost black mats on estuarine mud- or sandflats.

Dear Kathe,
Thanks for the id. It's nice to have another 'loose end' tied up. I hope you will be able to recognise some of the other unidentified sacoglossans as well.
Best wishes,
Bill Rudman.
