Ecological Notes:

Found on algal food source, especially Caulerpa racemosa. Depth range to at least 8 m.

Algal colour pigments are retained in the digestive system and the dorsal cerrata match the bubble like bladders of its food source, making this animal exremely difficult to find. Grows to 50 mm.
