The head and pectoral fins form a triangular disk at the front of the body. The posterior part of the body is thick and conical, like a shark. It has two large dorsal fins and a well-developed tail fin. The color varies from gray to brown, with a few pale spots on the body.
It is common from North Carolina to the Gulf of Mexico, although it is not reported in the Bahamas and the Caribbean. In Florida and Yucatán it is rare. Brazilian fish (R. horkeli) and southern fish (R. percellens) are two closely related species that occur from the West Indies to Brazil.
