The arapaima, pirarucu, or paiche (Arapaima gigas) is a South American tropical freshwater fish. It is a living fossil and one of the largest freshwater fishes in the world.
Arapaima can reach lengths of more than 2 m (6.6 ft), in some exceptional cases even more than 2.5 m (8.2 ft) and over 100 kg (220 lbs). The often cited maximum length of 4.5 m (14.8 ft) comes from a single second-hand-report from the first half of the nineteenth century, and is not confirmed.[citation needed] The maximum-cited weight for the species is 200 kg (440 lbs). As one of the most sought after food fish species in South America, it is often captured primarily by handheld nets for export, by spearfishing for local consumption, and, consequently, large arapaima of more than 2 m are seldom found in the wild today.
