These large shells are rounded with the left valve somewhat concave and the right quite flat. Valve surfaces have a flaky, layered (lamellose) appearance, and crumble easily (friable). Valve margins are undulating. Shell up to 18 cm across.
This species is closely related to the European Edible Oyster and was harvested extensively in the early years of European settlement until the population crashed during the nineteenth century. It was also a food source for indigenous communities. Today, it is no longer found in seafood markets.
Bays and inlets, in mud, from low tide to depth of 30 m.
