Nembrotha chamberlaini Gosliner and Behrens 1997

The second of four new species described by Gosliner & Behrens, 1997, Cal Acad. Proc. Vol. 49. No. 9, this beast is named in recognition of Dr. Marc Chamberlain of San Diego, California, a good friend, fantastic underwater photographer and a generous contributor to opisthobranch research.

This wild colored species only adds to the spectacular color of the Philippine reef seascape, with its vivid red and black marking against a white background. Splashes of yellow border these two color features while the edge of the foot, foot corners, cephalic ridge and genital aperture are bluish purple.

This large, up to 100 mm long, phanerobranch dorid is another excellent example of aposematic, or warning coloration. Common in shallow depths, throughout the Philippine Islands and Okinawa, it feeds on the tunicates, Rhopalaea sp., Clavelina moluccensis and Oxycorynia fascicularis.

The authors of this flamboyant species deny any relationship between the choice of the name chamberlaini and either the exceptionally common copulatory behavior observed during recent visits to the Philippines or the presence of particularly machismo penial armature .

Marc Chamberlain is by vocation a neurologist and by avocation a wildlife photographer. He enjoys traveling during which he is always toting cameras.
