Urotrygonidae is a family of rays native to the tropical and warm temperate marine waters of the Americas, commonly referred to as the American round stingrays. The two genera in this family were formerly placed within the family Urolophidae, whose species are now restricted to the Indo-Pacific. They have a round pectoral fin disk, a slender tail with a caudal fin, no dorsal fins, and a venomous tail spine.^[2]
