Sand devil length and at least in weight. The sand devil is found in the northwestern Atlantic Ocean from Massachusetts to the Florida Keys, where it is fairly common. It also occurs in the northern Gulf of Mexico, and there are additional unconfirmed records from Cuba, Jamaica, Nicaragua, and Venezuela. The southern extent of its range is uncertain due to confusion with the disparate angelshark ("S. heteroptera") and Mexican angelshark ("S. mexicana"). This bottom-dwelling shark is found over sandy or muddy bottoms on the continental shelf and slope. Off the eastern United States, the sand devil has been documented to migrate seasonally.
