White Dendronotus frondosus from Canada

November 2, 2002
From: Bill Rudman

Some time ago Marli Wakeling sent a photo of a small white Dendronotus which I first considered a small D. diversicolor and later as Dendronotus cf. dalli. While preparing today's message on swimming Dendronotus I checked Gordon Robilliard's (1970) review of the genus and saw his photo of the white form of D. frondosus which is almost certainly the same as the animal in Marli's photo. Robilliard, in a later WSM/AMU symposium, (1975) reports on his investigation of the ecology of D. frondosus in Washington State. He was convinced, by the quite distinct ecological separation in terms of food and habitat, that there were a number of species involved. To my knowledge this has never been further investigated.

Reference:
• Robilliard, G. A. 1975. The nudibranch Dendronotus frondosus - one species or four? The Festivus (San Diego Shell Club), 6(8): 44-47.

Best wishes,
