Rajiformes is the order of true rays and skates, flat-bodied cartilaginous fishes related to sharks. The spotted eagle ray, Aetobatus narinari, Euphrasen (1790 or bonnet ray is a Cartilaginous fish found in shallow coastal waters by Coral reefs Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Chondrichthyes or cartilaginous fishes are jawed Fish with paired fins paired nostrils scales two-chambered hearts and skeletons made of Cartilage rather Elasmobranchii is the subclass of Cartilaginous fish that includes Skates rays (batoidea, and sharks (selachii. Batoidea is a Superorder of cartilaginous fish containing more than 500 described species in thirteen families The smooth skates or leg skates are the ray family Anacanthobatidae. Dasyatidae is a family of rays, cartilaginous marine Fishes related to Skates and Sharks Dasyatids are common in tropical The butterfly rays are a family Gymnuridae, of rays.

Classification
There are several proposed classifications of fish in the superorder Batoidea. Batoidea is a Superorder of cartilaginous fish containing more than 500 described species in thirteen families In some classifications the order Rajiformes is split into two or three orders, the additional orders being Myliobatiformes, containing the eagle rays and their relatives; Rhinobatiformes, containing the guitarfishes (which may be further split into Rhynchobatiformes, containing the shovelnosed guitarfishes, and Rhiniformes, the guitarfishes). Myliobatiformes Compagno 1973 is a proposed order of rays. It is a sister group to Rajiformes, the true rays and contains the following families Eagle rays (the Myliobatidae family of Fish) are a family of mostly large rays living in the open ocean rather than at the bottom of the sea The guitarfish are a family Rhinobatidae, of rays. The guitarfish are known for an elongated body with a flattened head and trunk and small ray like wings The shovelnose guitarfish, Rhinobatos productus, is a ray that ranges from central California down to the Sea of Cortez. The guitarfish are a family Rhinobatidae, of rays. The guitarfish are known for an elongated body with a flattened head and trunk and small ray like wings

Dasyatidae is a family of rays, cartilaginous marine Fishes related to Skates and Sharks Dasyatids are common in tropical Dasyatidae is a family of rays, cartilaginous marine Fishes related to Skates and Sharks Dasyatids are common in tropical Named for the venomous spines along the tail; these contain a poison that causes pain and may cause symptoms such as nausea, vomiting, fever, chills, muscle cramps, tremors, paralysis, fainting, seizures, elevated heart rate, and decreased blood pressure (depending on the species). In addition, some species' toxins can be fatal to humans.

They are characterized by an extremely broad disc and a very short tail The sixgill stingrays are a family Hexatrygonidae, of rays containing a single genus Hexatrygon. The sixgill stingrays are a family Hexatrygonidae, of rays containing a single genus Hexatrygon. Eagle rays (the Myliobatidae family of Fish) are a family of mostly large rays living in the open ocean rather than at the bottom of the sea Eagle rays (the Myliobatidae family of Fish) are a family of mostly large rays living in the open ocean rather than at the bottom of the sea The largest of rays, including the giant manta rays. The manta ray ( Manta birostris) is the largest of the rays, with the largest known specimen having been more than 7 Most eagle rays have one poison-carrying spine.

The guitarfish are known for an elongated body with a flattened head and trunk and small ray like wings They have a body structure similar that of the sawfishes, but are not thought to be closely related. Sawfishes are a family of marine animals related to Sharks and rays.
