Family Synodontidae

Lizardfishes

 

Lizardfishes are known as 'Ulae in Hawaiian and Eso in Japanese.  Most are difficult to identify without considerable experience and color morphs make it even worse.  Saurida are easily distinguished by their tightly-packed bristle-like teeth on the lips.  Synodus have 'normal' conical teeth with gaps between them and Trachinocephalus has eyes set high and far forward allowing it to remain buried with only the eyes exposed.  All lunge rapidly into the water column to capture fishes.  These primitive fishes have a small spineless dorsal fin and stubby adipose fin (small flap of skin) on the caudal peduncle just like salmon.  Lizardfishes are very bony and poor for eating.  Large individuals will reach 1 foot in length.
