Ray - extremely flat-bodied cartilaginous marine fish, related to the shark.
The guitarfishes are a family, Rhinobatidae, of rays.
Notable species include the Shovelnose guitarfish, Rhinobatos productus, and the Bowmouth guitarfish, Rhina ancylostoma.

There are some fantastic creatures in this group-the freshwater sawfish, bowmouth guitarfish, Atlantic guitarfish, thornback, lesser electric ray, spotted electric ray, Atlantic torpedo, rough skate, round stingray.
The earliest known rays (probably guitarfish) date from the Jurassic period, about 150 million years ago. Since rays have no bones (only cartilage), fossil rays are rare, but their teeth, composed of very hard enamel, fossilize well.
Electric rays belong to the superorder Batoidea, which includes stingrays, skates, guitarfishes, and sawfishes. Like their relatives the sharks, batoids have skeletons made of tough connective tissue called cartilage.
