Penguin´s wing oyster (Pteria penguin)

The penguin’s wing oyster is a species of marine bivalve mollusc in the family Pteriidae, the pearl oysters. It is native to the western and central Indo-Pacific region and is used for the production of cultured pearls. It is found attached by its byssal threads to a number of different substrates but typically to hydroids, at depths of less than about 25 m. Wild oysters of this species seldom contain pearls.
