Tilapia are a large group of fish that include nearly one hundred different species.

Most of these fish live in warm freshwater places like rivers, lakes, and ponds. They are native to Africa and the Middle East. Some species can also live in brackish water, which is water that is slightly salty. Because they are so hardy, they can live in many different environments. Some even live in the Salton Sea, where the water is 30% saltier than the ocean.

These fish are very important to people for food and farming.

These fish have a very interesting way of eating and caring for their young. They have a second set of jaws called pharyngeal jaws. These are located in the throat and help them process food. Their true jaws, or mandibles, work with these throat jaws to eat many different things. This makes them very efficient at finding food. To protect their babies, many tilapia are mouth-brooders. This means the parents carry fertilized eggs and tiny fish in their mouths for several days. This keeps the young fish safe until they are strong enough to swim alone.

People have known about tilapia for thousands of years. In Ancient Egypt, the fish was shown in art and hieroglyphs. It was a symbol of rebirth and was linked to Hathor, the goddess of fertility.

In the Bible, a story tells of the apostle Peter catching a fish with a coin in its mouth. Many people believe this fish was a type of tilapia found in the Sea of Galilee. A Scottish scientist named Andrew Smith named the genus Tilapia in 1840. The name might come from the Tswana word "tlhapi," which means fish.

Today, tilapia are a major part of the global food industry. They are often called "aquatic chickens" because they are easy to farm. This is because they grow fast and can eat plants or algae instead of other fish.

In 2002, the world produced about 1.8 billion dollars worth of farmed tilapia. China is the largest producer, making 1.3 million tonnes every year. The United States is also a big consumer of this fish. In fact, it has been the fourth-most eaten fish in the U.S. since 2002. Farmers often grow mostly male fish because they grow much faster than females.

While tilapia are helpful for food, they can sometimes cause trouble. If they are moved to new warm places, they can become invasive species. This means they might crowd out the native fish that already live there. They are on a list of the world's worst invasive species for this reason. However, they cannot live in cold or temperate climates. Most tilapia will die if the water temperature drops below 12.8 degrees Celsius.
