Lizardfishes are benthic marine and estuarine bony fishes that comprise the aulopiform fish family Synodontidae. They are found in tropical and subtropical marine waters throughout the world.

Lizardfishes are generally small, although the largest species measures about 60 cm (24 in) in length. 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.
