Sap-sucking Sea Slug from Singapore

November 10, 2008
From: Toh Chay Hoon


Dear Dr Bill,

I came across this sap-sucking sea slug on a submerged reef off Southern Singapore during an intertidal trip. It was found on Bryopsis algae. Would you kindly help with its ID?

Locality: Cyrene Reef, intertidal, Singapore, South China Sea, 16 October 2008, Intertidal. Length: 5 mm. Photographer: Toh Chay Hoon.

Thank you,
Chay Hoon

Dear Chay Hoon,

We have this on the Forum as Elysia cf. japonica but if you look at the discussions under that species and Elysia abei there is still no clear agreement on whether they are all colour forms of one species or not. Certainly the blue on the rhinophores and the distinct yellow spots are characteristic of Elysia cf. japonica, but we are not sure if it is the same as Elysia japonica or E. abei, or both.

Best wishes,
Bill Rudman
