Ostreoidea is a taxonomic superfamily of bivalve marine mollusc, sometimes simply identified as oysters, [1] containing two families. The ostreoids are characterized in part by the presence of a well developed axial rod. [2]
Oysters feed most actively at temperatures ranging from the high 60s to the high 70s (20–26 °C). [8] Under ideal laboratory conditions, an oyster can filter up to 190 L (50 US gal) of water per day. Under average conditions, mature oysters filter 11–45 L (3–12 U.S. gal).

Oyster beds have an estimated 50 times the surface area of an equally sized flat bottom. The beds also attract a high concentration of larger predators looking for food.
