Among the Mollusca there is an abundance of Leda minuta, Yoldia myalls, Y. llmatula, Y. traclaeformis, Macoma calcarea, Saxicava arctlca and Cardium ciliatum. Among the Poly- chaeta the most numerous are Maldane sarsi; among the Crustacea Malda- nidae, Myriochele occulata, Chaetozone setosa, Scoloplos armlger and Mage- lone pacifica are distinguished by their numbers. The benthos biomass increases considerably (Fig. 409 and Table 321) at the entrance to the Inlet (500, 1,000 g/m3 and more) and in Gizigina Inlet (up to 1,000 g/m2); moreover, Mollusca and Echinodermata are predominant in the north of the Fig. 409. Distribution of benthos biomass in Penzhina Guba, Sea of Okhotsk, g/m2. (Vinogradova)..
