Family: Ostreidae

Ostreidae or true oysters are in the order of pterioda. True oyster species are hermaphroditic though some species produce generations that produce either male or female gametes.

Once the oyster is fertilized it sends up millions of eggs into the open water which develop into larvae in about six hours then mature fully in about two weeks.

Oysters are filter feeders using the mucus coating their gills to pull in suspended particles and plankton. The oyster can filter 5 liters of water a day. The oyster can also exchange gasses through their mantle which has small thin walled blood vessels lining it
