Tochuina tetraquetra
Tochuina tetraquetra (Pallas, 1788) or "Tochni" as it is called by the natives of the Kuril Islands, USSR, is the only species I am aware of that has human culinary value, The Kuril Indians eat the species raw or cooked. This species also has some commercial value being used in neurological research, because of its large brain ganglia. A large species it reaches up to 300 mm long. It is easy to identify being deep yellow-orange in color covered with white tipped tuberacles. The branchial plumes form an irregular series of low, white tufts along the margins. Its reported range extends from the Kurils in Russia south to Malibu, in Los Angeles County.
