Dear Bill,

I do not know which species this is ? Is it a sacoglossan ?

Locality: Kenting, 9 metres, Taiwan, 15 May 2005, Coral Reef. Length: 40 mm. Photographer: Kuang.

Hope that you can help,
Best wishes,

Dear Ching-Yao,
This is a pleurobranch, not a sacoglossan. It is Berthella martensi. If you look at other messages on this species you will see that it is a species which can drop off bits of its mantle as a defence strategy [see autotomy]. Your animal looks a bit strange because it has lost most of its mantle skirt, no doubt to avoid being mortally wounded by a predator.
Best wishes,
Bill Rudman
