We originally lumped these with Elysia sp. e481. The two species share the same habitat of Kwajalein lagoon Halimeda patches. Ten or more of these larger, mostly darker green specimens showed up scattered about the Halimeda patch on a dive on 27 January 2013. The next time we returned a month or so later, we saw none, and have not seen any since.
