Plakobranchus ocellatus is thought to be highly variable, but several authors posted messages that it is a species complex with up to 40 species lumped under this name. Almost all specimens have ocellae on the dorsal surface and on the parapodia. The rhinophores are white with bluish-purple tips. It is well-camouflaged, often half buried in the coral sand, here are 3 specimens. This shot shows two specimens mating and this one a colour form with dark blue rhinophores.
I read somewhere long ago a comment, if I remember correct of Cynthia D. Trowbridge, that up to 18 species are lumped under the
name Plakobranchus ocellatus  van Hasselt, 1824. One of them has recently been described: Plakobranchus papua  Meyers-Muñoz & van der Velde, 2016, I moved some similar looking specimens to Plakobranchus papua  Meyers-Muñoz & van der Velde, 2016.
Plakobranchus ocellatus is one of what Bill Rudman calls "Solar-powered Sea Slugs".
