Hypselodoris bullocki? - Feeding ?

May 27, 2006
From: Kerem Turker

Dear Bill,
Here are two Hypselodoris [H. bullocki? H. apolegma?] on the same diving location 20 meters from each other, which I think are feeding (I could not get a clear picture, whether this is actually a feeding action) on the same kind of sponge.

Locality: Island, 16 m, Kapalai - Malaysia, Celebes Sea, 09 November 2005, Sandy bottom with partly reef structure. Length: ~60 - 80 mm . Photographer: Kerem Turker.

Best Regards,
Kerem

Dear Kerem,
Firstly this species is part of what I have been calling the Hypselodoris bullocki group, for want of a better name, but I don't think it is actually Hypseldoris bullocki or H. apolegma. It will probably need a new name. For convenience I am leaving these unnamed species which look quite like H. bullocki with that species until they are sorted out.

As to its feeding. Although it looks like it couold be feeding, in both cases I am pretty sure the pinkish thing it is on is a large sea squirt or ascidian. certainly in the middle left photo there are small ascidians in the background and it is crawling over some middle-sized ascidians, so I am pretty sure that the bit in the foreground of that photo is also an ascidian. I have had a careful look at your hi resolution photos and there is no sign of the texture and pores that you would expect to see in a sponge.

Best wishes,
Bill Rudman
