Concerning message #20778:

Dear Bill,
I've been meaning to post a message with the attached picture for sometime now but I have had difficulty identifying the species. Thanks to the Forum ! With the triangular shaped gills though missing the yellow or white spots, can we conclude that this animal is also a Hypselodoris kanga? It seems to be feeding on a white substrate which is not too clear in my picture.

Locality: Lembeh Straight, N.E. Sulawesi, 10 meters, Indonesia, Celebes sea, 12 August 2007. Length: 25-30mm. Photographer: Kamal El Tawil.

Kindest regards,

Dear Kamal,
Yes I would identify this as H. kanga. We have quite a group of photos of this species on the Forum now and you can see an almost continuous series of photos from ones showing your 'spotless gills' form to ones with the 'typical' spotted gills.

I am certain it is feeding on the bluish? pinkish? sponge right in front of it. I think the white patch the extended oral tube is attached to, or reaching towards, is part of the sponge. From the network pattern of sponge fibres I can see I am pretty sure this is the species of Dysidea, probably unnamed, on which we have seen H. kanga feeding before.

Best wishes,
Bill Rudman
