Elysia sp. e604

This animal is colored a lot like Elysia e453, but in that species, the parapodia are very much reduced and topped with orange. In this specimen, the parapodia were wide and flaring, easily flopping back and forth in the light surge. Otherwise, the black spots along the parapodia and the color of the head are almost identical. They could simply be different growth forms of the same species. This one is so far the only one like it known, and it was damaged when found, with a split running nearly the entire length of the body. Still, it seemed to be functioning ok. It was found exposed on hard substrate on a shallow Kwajalein Atoll lagoon pinnacle at a depth of about 6m on 25 October 2009, and it measured about 40mm in length.

The next photo shows the split along the body that was present when it was found.
