Description

The freshwater longtom is a needlefish (Belonidae) from the fresh and brackish waters of Australia and New Guinea. The species grows to about 60 cm and has a very elongate, silvery body with long, thin jaws full of small, sharp teeth that project forward like a beak. It inhabits still and flowing rivers, from the tidal zone to far inland, and also impoundments. It often shelters near overhanging vegetation or submerged roots, from where it hunts small fishes at the surface. When disturbed it can leap from the water and inflict a puncture wound with its pointed beak.
