Osteoglossum is a genus of fish in the family Osteoglossidae. They reach about 1 m (3.3 ft) in length and are restricted to freshwater habitats in tropical South America.[1][2]

These predators mostly feed on arthropods like insects and spiders, but may also take small vertebrates such as other fish, frogs, lizards, snakes, mice, bats and small birds.[3][4] They jump up to 2 m (6.6 ft) out of the water to pick the prey off branches, tree trunks or foliage, which has earned them the local name "water monkeys".[3] They are the largest fish in the world that catch most of their food out of water.[3] When breeding, the male protects the eggs and young by carrying them in the mouth.[1][5]

They are sometimes kept in aquariums, but they are predatory and require a very large tank.[5]
