Elysia setoensis - feeding observations

May 14, 2000
From: Cynthia D. Trowbridge

Dear Bill,

Hi. Last month I asked about algal hosts of Elysia setoensis - I now can share some details. I am working in Japan with Dr. Yoshi Hirano. Last week I found two specimens of E. setoensis on the encrusting green algal host Codium adhaerens (which is common on low intertidal and subtidal rocky shores in Japan). In lab experiments, the slug also feeds on the upright, dichotomously branching Codium fragile. The specimens were found in front of the Misaki Marine Biological Station on the Miura Peninsula (the region that Satoru Hori found the species). E. setoensis is considerably smaller than the coexisting Elysia trisinuata.
All the best.

Cordially,
