Pinctada is a
Pearl oysters are not closely related to either the edible oysters of family Ostreidae or the freshwater pearl mussels of the families Unionidae and Margaritiferidae.
Species of commercial value
All species within the genus produce pearls. Attempts have been made to harvest pearls commercially from many Pinctada species. However, the only species that are currently of significant commercial interest are:
- Gulf pearl oyster, Pinctada radiata; Persian Gulf,[2] Red Sea, Mediterranean Sea and throughout the Indo-Pacific as far as Japan and Australia.
- Black-lip oyster, Pinctada margaritifera; Persian Gulf and southwestern part of Indian Ocean; Fiji; Tahiti; Myanmar; Baja California; Gulf of Mexico
- Gold-lip oyster, Pinctada maxima; Australia; Fiji; Tahiti;
- White-lip oyster, Pinctada maxima; Australia; Fiji; Tahiti; Myanmar;
- Pinctada mazatlanica; Mexico; Panama;
- Akoya pearl oyster, Pinctada fucata (also called P. martensii), Red Sea; Sri Lanka; Persian Gulf; Indian Ocean; Western Pacific Ocean; Australia; China; Venezuela;
- Shark Bay pearl oyster Pinctada albina; Australia
The various species of Pinctada produce different maximum sizes and colors of pearls, depending on the size of the species and the natural color of the nacre inside the shell. Black South Sea pearls, or Tahitian pearls come from the black-lip oyster; gold and silver South Sea pearls from the gold-lip and silver-lip oysters; and Akoya cultured pearls from Pinctada fucata martensii, the Akoya pearl oyster.
Pearls are also obtained in commercial quantities from some species of the closely related winged oyster genus Pteria.
Pearls are also produced from freshwater mussel species unrelated to pearl oysters. These freshwater species include Hyriopsis cumingii, Hyriopsis schlegelii, and a hybrid of the two species.
At danger from the large demand for pearls, the typical lifespan of a pearl oyster is usually around 3 years to 14 years. Pinctada maxima are seeded at about 2 years of age and take 2 years to fully develop a pearl. They can be reseeded up to 3 or 4 times. Akoya pearls are harvested after about 9 to 16 months.
