Description

The ladyfish is a slender, silvery predator of the family Elopidae reaching about 1 metre. The streamlined, herring-like body has large eyes, a terminal mouth and a deeply forked tail, a build for fast swimming in open water. The species lives in coastal water and runs far into brackish estuaries and lagoons along the western Atlantic coast from the USA to Brazil; it tolerates strongly varying salinities. In schools it hunts small schooling fish and shrimps. Like tarpon and eels it has a transparent, ribbon-shaped larval stage (leptocephalus). Among anglers it is known for its fast runs and leaps; the bony flesh is only moderately valued and is often used as bait.
