Red king crab (Paralithodes camtschatica). The food habits of the red king crab, a major component of the invertebrate biomass in the Bering Sea (Pereyra et al. 1976, Feder and Jewett 1980a), have been examined intensively by numerous investigators. Tarverdieva (1976) investigated the food of the red king crab in the southeastern Bering Sea, and found the main foods to be polychaete worms, sand dollars (Echinarachnius parma), gastropods of the families Trochidae and Naticidae, and pelecypods, of which Yoldia, Nuculana (= Leda), Nucula, and Cyclocardia (= Venericardia) were most often noted. Cunningham (1969) determined that echinoderms (a brittle star, Ophiura sarsi, a basket star, Gorgonocephalus sp., a sea urchin, Strongylocentrotus sp., and Echinarach- nius parma) were the most important food, by percent of total food weight ( percent), in the crab stomachs analyzed. He found that the percent frequency of occurrence of echinoderms in stomachs was 81 percent. Mollusks {hivslves—Nuculana radiata, Clinocardium californiense, Chlamys sp.; snaUs— Solariella sp. and Buccinidae) and crustaceans (crabs— Hyas coarctatus alutaceus, Erimacrus isenbeckii, and Pagurus sp.; and sand fleas—Amphipoda) were next in importance by weight with percent and percent, respectively (Cunningham 1
