Elysia trisinuata from Sagami Bay

Dear Bill,
Here is another of the sacoglossans that Yoshi Hirano kindly photographed for me in Sagami Bay, during this past May. It is Elysia trisinuata Baba, 1949 (Hiramiru-midorigai)

In May 2000, we found 30 specimens on the intertidal encrusting green alga Codium arabicum on Miura Peninsula, Japan. This species is distinguished by its "thread-thin white papillae" (Jensen 1985). All our specimens were large (up to 800 mg wet weight).
Distribution: Japan, Hong Kong, Hainan (Jensen 1998).
