We believe these are Elysia tomentosa, although it is possible more than one species are included in the photos below. In the Marshalls, it has been found at Kwajalein and Enewetak Atolls. At Kwajalein it was found crawling about on algae covered rocks on the leeward seaward reef.
The specimen below was in Caulerpa on a Kwajalein Atoll seaward reef at 13m on 23 May 2010.
