Gigantidas horikoshii is a species of large, deepwater, hydrothermal vent mussel, a marine bivalve mollusc in the family Mytilidae, the mussels.[1]

Description

Shells typically 160-170 mm in length, 60 mm in height, and 57 mm wide.[2]

Distribution

The type series was collected at a depth of 435-762 m from hydrothermal vents surrounding Kaikata Seamount, near the Ogasawara Islands, Japan.[2] It has also been recorded from the Sumisu Caldera hydrothermal vent field at a depth of 694 m (31°28.2113'N, 140°4.2833'E) in the Izu Islands arc. Mellado et al. (2022) reported a juvenile specimen from waters to the east of Taiwan.[3]
