A bivalve mollusk of the Veneridae family. This species was previously classified as a species of the Venus genus, hence the name Venus shell. It is grayish-white in color, which does not imply a beautiful Venus. The shell is large and thick, oval-triangular in shape, 10 cm long, 8 cm high, and 5 cm bulged. The surface is grayish-white with dense thin growth ribs all over, and many thin radial lines between them. The inside is white. The inner edge of the shell is finely notched. It is found in the Tohoku region, Hokkaido, the Kuril Islands, Sakhalin, and Primorsky Krai, and lives on fine sandy bottoms from the intertidal zone to a depth of 20 m.
