The taxonomic composition and the zonal-geographical characteristics of amphipods (Amphipoda: Gammaridea, Caprellidea) in the sublittoral zone of Anadyrsky and Mechigmensky gulfs (the Bering Sea)
Analysis of the benthos samples collected in 2005 and 2001 in the Anadyrsky and Mechigmensky gulfs and of the gray whale stomach food lump samples for 2007–2009 has revealed 142 species of amphipods, representing 65 genera, 25 families and two suborders. The benthos fauna of these gulfs, taking into account data from literature, may include 150 amphipod species, including Dyopedos spinosus(?) (Stephensen, 1944), Anonyx robustusGurjanova, 1962, Pseudoanonyx caecusKudrjaschov, 1965, Boeckosimus normani(G. Sars, 1895), Boeckosimus simus (Gurjanova, 1962), Lepidepecreum kasatka Gurjanova, 1962, Aceroides kobjakovae Bulycheva, 1952, Arrhis luthkeiGurjanova, 1936, Monoculodes diamesus (Gurjanova, 1936), Monoculodes semenoviGurjanova, 1938, Westwoodilla coecula(?) (Date, 1856), Pardalisca tenuipesG. Sars, 1893, Stenula arctica(?) Gurjanova, 1951, Caprella longicirrata Vassilenko, 1974 registered in Bering Sea for the first time. A number of taxonomic units identified as “sp.” are most likely new species; three species from the families Phoxocephalidae, Stenothoidae and Pardaliscidaerepresent genera never observed in Russian waters before.
The sublittoral zone of the Anadyrsky and Mechigmensky gulfs is inhabited by predominant cold-waters species of the boreal-polar complex, and the littoral zone – by endemics of the Pacific boreal region.
