A green to gray-green sacoglossan of about 4 cm (1.6 in), its side flaps bordered pale and finished with a fine dark line, the body scattered with white flecks. The flaps are usually carried loosely folded rather than spread, which alters the outline enough to confuse an identification made from a single photograph.
It grazes green algae on sheltered reef and rubble, draining cells one at a time and keeping the chloroplasts. Beyond that the species is barely studied - like many of the smaller sacoglossans it is known mostly from scattered photographic records and a handful of collected specimens, and its full range is a matter of guesswork. That is worth saying plainly rather than filling with what is true of the genus: a slug this small and this green gets recorded when somebody happens to look closely, and nowhere else.
