Description

The Atlantic lizardfish is a bottom-dwelling predator of the family Synodontidae reaching about 40 cm. The species owes its name to the lizard-like head with a wide mouth full of fine, sharp teeth and to its upward-set eyes. The streamlined, brownish mottled body gives excellent camouflage on sand and gravel bottoms of the eastern Atlantic and the Mediterranean, from shallow water to several hundred metres. The lizardfish is an ambush hunter: it half-buries itself in the sand and darts upward to seize passing small fish and crustaceans. Because of its size it is sometimes eaten, but it has little commercial value.
