Tilapia ( tih-LAH-pee-?) is the common name for nearly a hundred species of cichlid fish from the tilapiine cichlid tribe. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers and lakes and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water.
Tilapia is the fourth most consumed fish in the United States dating back to 2002. The popularity of tilapia came about due to its low price, easy preparation, and its mild taste.

History
Tilapia was a symbol of rebirth in Egyptian art, and was in addition associated with Hathor. It was also said to accompany and protect the sun god on his daily journey across the sky. Tilapia painted on tomb walls, reminds us of spell 15 of the Book of the Dead by which the deceased hopes to take his place in the sun boat: "You see the tilapia in its [true] form at the turquoise pool", and "I behold the tilapia in its [true] nature guiding the speedy boat in its waters."
Tilapia were one of the three main types of fish caught in Biblical times from the Sea of Galilee, specifically the "Galilean Comb" (Tilapia galilea). Today, in Modern Hebrew, the fish species is called Amnon (Suggested derivative: Am= mother, Noon= fish.), although also known as "St. Peter's fish". The name "St. Peter's fish" comes from the story in the Gospel of Matthew about the apostle Peter catching a fish that carried a coin in its mouth, though the passage does not name the fish. While the name also applies to Zeus faber, a marine fish not found in the area, a few tilapia species (Sarotherodon galilaeus galilaeus, Paratilapia sacer, and others) are found in the Sea of Galilee, where the author of the Gospel of Matthew recounts the event took place. These species have been the target of small-scale artisanal fisheries in the area for thousands of years.
The common name tilapia is based on the name of the cichlid genus Tilapia, which is itself a latinization of thiape, the Tswana word for "fish". Scottish zoologist Andrew Smith named the genus in 1840.

Characteristics
Tilapia typically have laterally compressed, deep bodies. Like other cichlids, their lower pharyngeal bones are fused into a single tooth-bearing structure. A complex set of muscles allows the upper and lower pharyngeal bones to be used as a second set of jaws for processing food (cf. morays), allowing a division of labor between the "true jaws" (mandibles) and the "pharyngeal jaws". This means they are efficient feeders that can capture and process a wide variety of food items. Their mouths are protrusible, usually bordered with wide and often swollen lips. The jaws have conical teeth. Typically tilapia have a long dorsal fin, and a lateral line which often breaks towards the end of the dorsal fin, and starts again two or three rows of scales below. Some Nile tilapia can grow as long as two feet.
Other than their temperature sensitivity, tilapia exist in or can adapt to a very wide range of conditions. An extreme example is the Salton Sea, where tilapia introduced when the water was merely brackish now live in salt concentrations so high that other marine fish cannot survive.
Tilapia are also known to be a mouth breeding species. Mouth breeding means they carry the fertilized eggs and young fish in their mouths for several days after the yolk sac is absorbed.
