Dear Bill,

I captured this image of nudibranchs in Lembeh Strait and I'm unable to identify it exactly. Could you please identify it for me?

Locality: Lambeh strait, 15 m, Indonesia, North Sulawesi, Indo Pacific, 30 april 2006, muck dive. Length: 50-70 mm. Photographer: Francois Zylberman.

Thanks
Francois

Dear Francois,

I am pretty sure this is Hypselodoris nigrostriata, but I find it pretty difficult to distinguish it from H. zephyra.  As you will see from comments I have made in messages concerning both species I have some doubts about whether we are dealing with one or two species here.

Of more interest is that these two animals are feeding on the dark blue sponge. The oral tube of the animal on the right of your photo is clearly visible. The sponge is almost certainly a species of Dysidea, and probbaly the same species as H. kanga is eating in your message #20778.

Best wishes,
Bill Rudman
