description Smooth Butterfly Ray Overview
The smooth butterfly ray is a benthic marine fish found primarily in the western Atlantic Ocean, ranging from the coastal waters of Maryland down to Brazil. Scientifically known as Gymnura micrura, it is easily distinguished by its broad, diamond-shaped body and the complete absence of a tail spine, which contributes to its common name. The species inhabits shallow coastal waters, including bays and estuaries, where it camouflages itself under sand or mud to ambush small fish and invertebrates. It is targeted by commercial and recreational fisheries in certain parts of its geographic range.
