Dendrodoris tuberculosa from East Kalimantan

Dear Bill

I swear, I've (almost) clicked through your entire database as well as various books on the subject but I haven't been able to possitively identify the attached slug.

Locality: Kakaban Island, Berau District, 5-6 metres, East Kalimantan, Indonesia, Indo-Pacific, 25 September 2002, Hard and soft coral covered. Length: About 8-10 cm. Photographer: Claus Gregersen.

I'm afraid I can supply these low-res video grabs only - unless you want the live footage, of course.

The colours in the photos are quite true to life. One thing, you'll notice, are the ball-pointed rhinophores. In one picture the left rhinophore is retracted leaving only the ball visible.

Trust you can help :-)

Best wishes
Claus

Dear Claus,
This is Dendrodoris tuberculosa. It is a very well camouflaged species and as you will see on the Fact Sheet, its most distinctive feature is the presence of opaque white spots on the underside of the mantle - which of course don't appear in photos. Have a look at Carmen Loke's recent  message [#17135] which shows a rather colorful variety. I note there, as you do, how distinctive the rhinophore clubs are.

Best wishes,
Bill Rudman
