Lizardfishes, sauries and bombay ducks are the common names used for the members of Synodontidae family. They occur in the Atlantic, Indian and Pacific oceans. They are mainly saltwater fishes but can also occur in brackish water. They are recognized as small cylindrical fishes with spineless fins and large mouth full of slender sharp teeth, even on tongue. They are commonly called lizardfishes, due to their resemblance to lizard.
Lizardfishes are bottom-living fishes found in coastal, estuarine, and offshore shelf waters, to depths of about 300 m. They are voracious predators, feeding mainly on other small fishes and crustaceans.
There are 3 genera and about 68 species of Synodontidae worldwide. Malaysia has 3 genera and about 16 species.
