Genera | |
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 combined range of the various species is tropical, subtropical, and temperate waters worldwide. They often travel in large schools.
Description
Guitarfish have a body form intermediate between those of sharks and rays. The tail has a typical shark-like form, but in many species, the head has a triangular, or guitar-like shape, rather than the disc-shape formed by fusion with the pectoral fins found in other rays.[2]
Reproduction
Guitarfish are ovoviviparous; the embryo matures inside an egg inside the mother until it is ready to hatch. This is typical of rays.
Habitat
Guitarfish are bottom feeders, which bury themselves in mud or sand and eat worms, crabs, and clams.[3] Some can tolerate salt, fresh, and brackish water.[4] They generally live close to the beach/coastline or in estuaries.[4]

Nelson's 2006 Fishes of the World recognized four genera in this family: Aptychotrema, Rhinobatos, Trygonorrhina, and Zapteryx; other taxa once placed in the Rhinobatidae, such as Platyrhinoidis and Rhina, have since been moved to their own families. Recently, the genus Glaucostegus has again become recognized as distinct from Rhinobatos. The status of Tarsistes is dubious.
