General Description

Body soft, dark grey-brown. Body wall is slightly leathery and lacks ossicles. Up to 6 mm long.

Biology

This is one of the smallest holothuroids in the world. Sexes are not separate, and all specimens have two "pockets" (marsupia) at the oral (mouth) end of the dorsal body. The two small ventral tentacles have been observed extending back to the openings of these marsupia from where small tube feet extend, presumably the means of putting eggs or embryos into the marsupia.

Habitat

Attached to brown seaweed fronds in high wave energy parts of the coast, to depth of at least 2 m.
