This elongated slug has a long tail-like rear end. Its pale green body has white and blue markings, and it is found on or near Caulerpa algae.
In adults, the side flaps partly or fully cover a translucent, rounded shell. White papillae line the flaps and the middle of the tail.
It has been found on many Caulerpa species, especially Caulerpa racemosa, and sometimes under rocks or crawling beside algae. It can release a white secretion and detach its tail when disturbed.
