Abstract—The quantitative distribution of the starfish was analyzed in Vostok Bay, Nakhodka Bay, and Kievka
Bay (the Sea of Japan). Nine species were found. Three species of Asteroidea dominated (Asterina pectinifera,
Asterias amurensis, and Leptasterias sp.). The population density of A. pectinifera and A. amurensis was higher
in the shallow waters compared to the sublittoral zone. The frequency of the occurrence, the biomass, and the
population density of Leptasterias sp. were the highest for the shallow waters and decreased accordingly when
the water temperature decline on the transect from Vostok Bay to Kievka Bay. In Kievka Bay, which was char-
acterized by the lowest water temperatures, Leptasterias sp. dominated in the littoral and sublittoral zones fol-
lowed by A. pectinifera and A. amurensis.
