Bhave, V.J., 2009 (May 18) Costasiella sp. from Ratnagiri, India. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/22422Dear Vishal,
Although the cerata remind us of an aeolid, this is in fact a herbivorous sacoglossan,Costasiella sp. 3. One clue to its identity is the position of its black eyes - very close together in the dorsal midline between the head tentacles. Species of Costasiella have usually been found associated with species of the green algal genus Avrainvillea
Best wishes,
Bill Rudman
