The Short-tailed Sea Slug is one of the more commonly seen Victorian nudibranchs and has a pink or orange body, with red or purple spots around the margin. Each spot is surrounded by a white edge. Up to 15 cm long
This spectacular animal can be found in rockpools or on the reef edge where it feeds on sponges or bryozoans often toxic to other species. The group name nudibranchs refers to the naked gills seen as the retractable feathery structures located towards the rear on these animals backs, often seen when feeding or undisturbed.
