2, see text 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] 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.
