Arapaima is a genus of large freshwater fish native to South America. There are two species: the arapaima (Arapaima gigas) and the less well-known arapaima leptosoma.
Arapaima can grow up to 3 meters (9.8 feet) in length and weigh up to 200 kg (440 pounds). They have a torpedo-shaped body covered in large, shiny scales that can be up to 15 cm (5.9 inches) in diameter. They have a distinctive elongated head and a small, toothed mouth.
Arapaima principally inhabit rivers and lakes throughout the Amazon Basin. They are found in a variety of environments, including deep pools, rapids, and flooded forests.
Arapaima are top predators, preying on fish, crustaceans, and even birds that venture too close to the water's surface. They are able to breathe air using a specialized organ called a labyrinth organ, which allows them to survive in oxygen-poor environments.
Arapaima populations are declining due to overfishing and habitat destruction. Some countries, such as Brazil, have implemented conservation measures to protect the species in certain areas.
