Yellow Phase of Archidoris odhneri
October 5, 2003
From: Clinton Bauder
Hi Bill,
I'm back from another Alaska trip. This trip wasn't as successful from a nudibranch standpoint as previous trips north but that may have had as much to do with my new wide angle video setup (= not the best for shooting nudibranchs) as anything else. As usual, though, the diving was excellent.
Anyway I saw several of these large (15 cm or more) yellow dorids which I believe are Archidoris odhneri. The pictures are from St Lazarius Island which is near Sitka, Alaska. Depth was about 20m. Interestingly a couple of times I found them sharing a food-sponge (Myxilla lacunosa?) with a brown-spotted yellow dorid I identified as Archidoris montereyensis (see lower left of the uppermost photo).

Thanks Clinton,
Your animals certainly look like Archidoris odhneri but I am too much of a coward to agree or disagree with your identification of the brown-spotted yellow animal in the top photo.
Best wishes
Bill Rudman
