Charcotia granulosa is a species of sea slug, a metarminid nudibranch, a marine gastropod mollusc in the family Charcotiidae.[2]

Etymology

The genus name is a tribute to Dr. Jean Charcot, who led the expedition which discovered this species.

Distribution

This species was described from a single specimen found at 40 m depth at Booth Island, Antarctica. It has been described in more detail from specimens collected at Signy Island, Antarctica.[3]

Description

The body of Charcotia granulosa is translucent white with branches of the pink digestive gland showing through the skin. The mantle is bordered by an opaque white band and the dorsal surface is covered by pointed tubercles which are tipped with white pigment. The rhinophores are translucent and tipped with white.[4]
