Yoshi and Yayoi Hirano have published to interesting studies showing that this species in Japan feeds exclusively on hydroids of the genus Obelia, while another species, E. horii, which is found abundantly with E. misakiensis feeds only on Plumularia filicaulis.

NOTE: Reports below suggest this species has a wide distribution on both the west and east coasts of the northern Pacific BUT note Bernard Picton's message suggesting there are a number of species involved here.
