The lizardfish (or typical lizardfish to distinguish them from the Bathysauridae and Pseudotrichonotidae) are a family, the Synodontidae, of aulopiform fish. They 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 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.
They are bottom-dwelling fish, living in shallow coastal waters; even the deepest dwelling lizardfish lives in waters no more than 400 m (1,300 ft). 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.
