Description

The brushtooth lizardfish is a lizard-like bottom predator of the family Synodontidae reaching about 50 cm. The species has a wide mouth full of fine, brush-like teeth, an adipose fin and a row of spots along the lateral line; the brownish mottled body gives camouflage on sand and gravel bottoms. It is originally widespread in the Indo-Pacific but has entered the eastern Mediterranean through the Suez Canal, where as a Lessepsian migrant it has become locally numerous. As an ambush hunter it darts upward to seize small fish and crustaceans. In the eastern Mediterranean it has become a valued commercial fish.
