An uncommon tiny sea slug, black with two rows of short club shaped cirrata (body flaps) along each side of the body. Both the rhinophores (sensory structures) and the tail are short. It is black and can have a white streak down the centre of the back. The foot is grey.

Sometimes found on mudflats amongst filamentous green algas.

Most likely predates on other sessile invertebrates, small crustaceans and perhaps each other. Often found associated with either Seagrass or the green alga Enteromorpha sp. Although, this is generally an uncommon species, occasionally it can be seen in very large numbers.
