It is a bivalve mollusca of the family Veneridae in the class Bivalvia of the phylum Mollusca. In Japan, it is found throughout the Pacific Ocean south of the Boso Peninsula and the Sea of Japan south of Yamagata Prefecture, even reaching Taiwan. It inhabits the fine sandy bottom of shallow seas, and its shell is 50 mm long and 37 mm high, triangular and weakly bulging. The shell surface is white or gray-blue with usually 3-4 dark blue radial bands running from the apex, and fine spots all over. These colors change to brown when boiled. The inside is white, and the meat is delicious. A similar species, G. meleaagris , is slightly larger and found as far as Hokkaido, and is also edible.
