Chinese name:舌骨牡蛎,砗磲牡蛎

The giant honeycomb oyster (Hyotissa hyotis) is a very large saltwater oyster, a marine bivalve mollusk.

Species in this family are known as honeycomb oysters or "foam oysters" because under magnification, their shell structure is foam-like.

Like most bivalves, the giant honeycomb oyster is a filter feeder.
