Ostreidae

Ostreidae

Overview

Ostreidae Rafinesque, 1815

Common Name: True oysters

Extant/Extinct

Key morphological features: The valves are subequal, with the left valve often more inflated than the right valve, although this is not true of all genera and also can depend on the attachment surface on which the oyster grows.

        SIZE: 

Paleoecology: The Ostreidae have had a global distribution since the Jurassic Period where modern oysters inhabit all continents except Antarctica. They inhabit a wide range of marine environments including full marine to brackish salinities and tropical to temperate latitudes. Preferring to attach to hard substrates, some species aggregate to form reef or bed structures.

        MOBILITY: Stationary

        FEEDING MODE: Suspension Feeder

        HABITAT: Epifaunal
