Tilapia (/ t ɪ ˈ l ɑː p i ə / tih-LAH-pee-ə) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. [2]

Relative to their size they have one of the widest gapes of any fish. The lower jaw has no ethmoid membrane (floor) and is attached only by the hinge and a modified tongue bone. There are several large, fang-like teeth in the front of the jaws, followed by many small barbed teeth.
Also, hybrids between certain parent combinations (such as between Mozambique and Wami tilapia) result in offspring that are all or predominantly male. Male tilapia are preferred in aquaculture as they grow faster and have a more uniform adult size than females. The "Florida Red" tilapia is a popular commercial hybrid of Mozambique and blue ...
Farmed tilapia production is about 1,500,000 tonnes (1,700,000 short tons) annually, with an estimated value of US$1.8 billion, [107] about equal to that of salmon and trout. Unlike those carnivorous fish, tilapia can feed on algae or any plant-based food.
The upper jaw is often formed largely from the premaxilla, with the maxilla itself located further back, and an additional bone, the sympletic, linking the jaw to the rest of the cranium. [ 15 ] Although the skulls of fossil lobe-finned fish resemble those of the early tetrapods, the same cannot be said of those of the living lungfishes.
The Wami tilapia is a tilapiine cichlid that grows to over 20 cm in length and is considered a useful food fish in Tanzania and the island of Zanzibar, which is recognized as a potential origin. It is tolerant of brackish water and grows well in saline pools, making it particularly suitable for aquaculture by communities living close to the sea.
