Gerreidae - mojarras

Mojarras are moderately deep-bodied, silvery fishes with deeply forked tails and strongly protrusible jaws which point downward when protracted or extended. Their lower jaw profile is concave, and they possess a scale-like axillary process (modified protruding scale) at the pelvic fin base. The dorsal and anal fins have a scaly sheath at the base in which the fins can fold into. Mojarras are generally small fishes and prefer sand or mud bottoms where they feed on bottom-dwelling organisms.
