General Description

Body soft, cucumber-shaped, grey-blue to grey-brown with fine dark flecks, oral (mouth) and anal ends usually black. Up to 5 cm long.

Biology

Females seasonally brood many small juveniles in an internal body cavity (coelom) during late winter for release in spring. By late summer one or a few large juveniles have been found in the coelom of some females, indicating that auto-ingestion/"cannibalism" occurs to enhance species survival.

Habitat

Under or around the edges of rocks, and on seaweed, to depth of at least 6 m.
