Description

The hound needlefish (Tylosurus crocodilus) is a large, elongate predator of the family Belonidae occurring worldwide in tropical seas. The species has a silvery, needle-shaped body with a blue-green back and long jaws full of sharp teeth, and can reach about 1.5 metres. It lives pelagically over lagoon and seaward reefs, alone or in small groups, and hunts fishes at the surface. When startled or attracted to bright light the species can leap from the water at high speed; people have been seriously injured by the beak-like snout. The species is a valued sport and food fish.
