Pinctada margaritifera

Pinctada margaritifera, commonly known as the black-lip pearl oyster, is a species of pearl oyster, a saltwater clam, a marine bivalve mollusk in the family Pteriidae. This species is common in the Indo-Pacific within tropical coral reefs. The ability of P. margaritifera to produce pearls means that the species is a valuable resource to humans. The oysters are harvested wild from coral reefs and are also commonly grown in aquaculture, both primarily taking place in the Indo-Pacific region.
