This unidentified species is similar to and could be a variation of the one we are calling Elysia tomentosa. Since there are some seemingly consistent differences in coloration, we are keeping it under a separate listing for now. The specimen in the frist three photos below was found at Kwajalein Atoll crawling on sand and rubble near a Halimeda algae patch at a depth of 8m on 1 September 2008. It measured 14mm in length.
The specimen below was found on Halimeda in Kwajalein lagoon on 15 September 2008.
An especially "furry" 15mm specimen (below) and another at 12mm were found by John and Lynette Flynn in 1-2m of water under slabs in the lee of an island in northeast Rongelap Atoll.
This one was found with its orange spiral egg mass on the underside of a living top shell, Rochia nilotica.
A couple more specimens from Kwajalein Atoll. The trace of red-brown ini the parapodial margins kind of ties these to Elysia tomentosa.
