The lizardfish [note 1] are a group of benthic marine and estuarine bony fish that comprise the aulopiform fish family Synodontidae. Lizardfish are found in tropical and subtropical marine waters throughout the world.
Lizardfish are generally small fish, although the largest species are about 60 cm (24 in) long. They have slender, somewhat cylindrical bodies, and heads that superficially resemble those of lizards. The dorsal fin is located in the middle of the back, and accompanied by a small adipose fin placed closer to the tail. They have mouths full of sharp teeth, even on the tongue.
All lizardfish are benthic animals that live in shallow coastal waters; even the deepest-dwelling lizardfish lives in waters no more than 400 m (1,300 ft) deep. Some species in the subfamily Harpadontinae even live in brackish estuaries. They prefer sandy environments, and typically have body colours that help to camouflage them in such environments.
