Species of fish
The payara, Hydrolycus scomberoides, is a species of dogtooth tetra. This predatory fish is found in the Amazon Basin in tropical South America.[2][3] It was the first of four species to be described in the genus Hydrolycus.[4]
Description[edit]The most noticeable feature of H. scomberoides is the two long fangs protruding from its lower jaw. These are used to impale their prey, mostly smaller fish.[3] It typically reaches a standard length of about 30 cm (1.0 ft),[3][4][5] but can reach up to 51 cm (1.7 ft).[6] There are reports of far larger individuals, up to 1.17 m (3.8 ft) in total length and 17.8 kg (39 lb) in weight, based on records by IGFA,[2] but this likely involves confusion with the related H. armatus.[3][4]
