Body oval shape, soft and smooth, black to brown. Up to 3 cm long.
Females seasonally brood many juveniles in an internal body cavity (coelom) during late winter for release in spring. The presence of embryos of different size, and evidence of mid-body constriction, suggest that cloning occurs within the coelom. There is some evidence that the form in southeast Tasmania may be a separate species. A larger red to orange-coloured form in eastern and western Victoria and South Australia is yet to be described and named.
Rock crevices and on seaweed, to depth of at least 26 m.
