The guitarfish, also referred to as shovelnose rays, 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 warm temperate waters worldwide.
Trygonorrhina, also known as the fiddler rays or banjo rays, is a genus of guitarfish, family Rhinobatidae. The two species are found along the eastern and southern coasts of Australia. They are benthic in nature, favoring shallow, sandy bays, rocky reefs, and seagrass beds. The eastern fiddler is found to a depth of 120 cm and the southern fiddler to a depth of 180 cm.
Rhina ancylostoma, the bowmouth guitarfish, shark ray or mud skate, is a species of ray and a member of the family Rhinidae. Its evolutionary affinities are not fully resolved, though it may be related to true guitarfishes and skates. This rare species occurs widely in the tropical coastal waters of the western Indo-Pacific, at depths of up to 90 m (300 ft). Highly distinctive in appearance, Rhina ancylostoma has a wide and thick body with a rounded snout and large shark-like dorsal and tail fins. Its mouth forms a W-shaped undulating line, and there are multiple thorny ridges over its head and back. It has a dorsal color pattern of many white spots over a bluish gray to brown background, with a pair of prominent black markings over the pectoral fins. This large species can reach a length of 2.7 m (8.9 ft) and weight of 135 kg (298 lb).
The thornback guitarfish is a species of ray in the family Platyrhinidae, and the only member of its genus. Despite its name and appearance, it is more closely related to electric rays than to true guitarfishes of the family Rhinobatidae. This species ranges from Tomales Bay to the Gulf of California, generally in inshore waters no deeper than 6 m (20 ft). It can be found on or buried in sand or mud, or in and near kelp beds. Reaching 91 cm (36 in) in length, the thornback guitarfish has a heart-shaped pectoral fin disc and a long, robust tail bearing two posteriorly positioned dorsal fins and a well-developed caudal fin. The most distinctive traits of this plain-colored ray are the three parallel rows of large, hooked thorns that start from the middle of the back and run onto the tail.
The lesser guitarfish or lesser sandshark is a species of fish in the Rhinobatidae family.
Rhinobatos is a genus of fish in the Rhinobatidae family. Although previously used to encompass all guitarfishes, it was found to be polyphyletic, and recent authorities have transferred many species included in the genus to Acroteriobatus, Glaucostegus, and Pseudobatos.
The bluntnose guitarfish or fiddlefish is a species of fish in the Rhinobatidae family. It is found in Namibia and South Africa. Its natural habitats are shallow seas and estuarine waters. It is threatened by habitat loss.
The brown guitarfish is a species of fish in the Rhinobatidae family. It is found in western Pacific of Taiwan and the Philippines. Its natural habitats are open seas, shallow seas, coral reefs, and estuarine waters. The Taiwan guitarfish was formerly considered a distinct species, but is now considered a junior synonym.
The bareback shovelnose ray or nakedback guitarfish, is a species of fish in the Rhinobatidae family. It is found in Seychelles and Mauritius. Its natural habitat is open seas.
The flathead guitarfish or Pacific guitarfish is a species of cartilaginous fish in the Rhinobatidae family. It is found in shallow seas around Chile, Ecuador, Peru, and possibly Nicaragua. Its natural habitat is the open sea.
The common shovelnose ray, giant shovelnose ray or giant guitarfish is a species of fish in the Rhinobatidae family found in the central Indo-Pacific, ranging from India to the East China Sea, Solomon Islands and northern Australia. It is found in shallow coastal areas to a depth of at least 100 m (330 ft), including mangrove, estuaries and reportedly also in freshwaters. It reaches up to 2.7 m (8.9 ft) in length, and is greyish-brown to yellowish-brown above with a paler snout.
The Zanzibar guitarfish is a species of fish in the Rhinobatidae family endemic to Tanzania. Its natural habitats are open seas and shallow seas.
Rhynchobatus australiae, also called the white-spotted guitarfish, white-spotted wedgefish or bottlenose wedgefish, is a species of fish in the Rhinidae family. It is found from shallow waters to a depth of at least 60 m (200 ft) in the Indo-Pacific, ranging from the East African coast and the Red Sea, to Taiwan, the Philippines and Australia. It is part of a species complex that also includes the giant guitarfish, the broadnose wedgefish and possibly the smoothnose wedgefish.
The banded guitarfish, mottled guitarfish, prickly skate or striped guitarfish is a species of fish in the Trygonorrhinidae family. Originally Z. exasperata was placed in the Rhinobatidae family, however recent mitochondrial DNA analysis shows their placement into the new family of Trygonorrhinidae. They are found from shallow water to a depth of 200 m (660 ft) in the East Pacific from California, United States, to Mazatlan, Mexico, including the Gulf of California. The species has also been recorded further south, but this likely involves its close relative, the southern banded guitarfish.
The eastern shovelnose ray is a species of guitarfish in the family Rhinobatidae of order Rhinopristiformes. The species is endemic to the east coast of Australia and inhabits subtropical and temperate waters from southern Queensland to southern New South Wales.
The common guitarfish is a species of cartilaginous fish in the family Rhinobatidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea. It is a bottom-dwelling fish feeding on crustaceans, other invertebrates and fish. The females give birth to live young. Its lifestyle makes it vulnerable to trawling and other fishing methods, populations seem to be declining and it has disappeared from parts of its range.
The blackchin guitarfish is a species of cartilaginous fish in the family Rhinobatidae. It is native to the eastern Atlantic Ocean and the Mediterranean Sea. It is a bottom-dwelling fish feeding on crustaceans, other invertebrates and fish. The females give birth to live young. Its lifestyle makes it vulnerable to trawling and other fishing methods, populations seem to be declining and it is subject to intensive fishing pressure, with its fins being sold into the Asian market. The International Union for Conservation of Nature has assessed its conservation status as being "critically endangered".
Acroteriobatus is a genus of fish in the Rhinobatidae family. Although its constituent species were previously assigned to Rhinobatos, recent authors treat it as distinct.
Pseudobatos is a genus of fish in the Rhinobatidae family. Although its constituent species were previously assigned to Rhinobatos, recent authors treat it as distinct.
Acroteriobatus omanensis, the Oman guitarfish, is a type of guitarfish of the family Rhinobatidae found in Gulf of Oman and Arabian Sea. There has only been a handful of specimens discovered in fish landings in Muscat. Therefore, its population and potential threats are not specifically known to scientists.
