Wikipedia Abstract

Strongylura marina, known commonly as the Atlantic needlefish, is a common demersal needlefish species common in marinas and other areas with minimal current. Its extremely long jaw and body set this fish apart from other predators. Atlantic needlefish are found from Maine to Brazil and have been known to venture into freshwater for short periods.
