Concerning message #15764:

Hi Bill,

Sandra's the expert and has indeed done dissections confirming the presence of Adalaria proxima in the north Pacific (Millen 1987). Additionally, a few years ago I confirmed the identity of two specimens I collected in 1999 from Prince William Sound, Alaska by examining their radulae. One specimen, 3 mm long preserved, had a radular formula of 30 x, while the second specimen, 10 mm long preserved (and whose radula is pictured here), had a formula of 36 x The arrangement of the spicules in the dorsum and tubercles of both of these specimens was the same as in Dong Bum Koh's specimen from South Korea.

Locality: Cordova, Prince William Sound, Intertidal, Alaska, North Pacific, 13 August 1999, Rock jetty. Length: 10 mm (preserved adult). Photographer: Jeff Goddard
