Pseudobatos prahli, also known by its common name Gorgona guitarfish [1] is a species from the genus Pseudobatos . [2] [3]
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.
The shovelnose guitarfish, Pseudobatos productus, is a ray in the family Rhinobatidae. It becomes mature at an estimated seven to eight years old. Males are between 90–100 cm (35–39 in) long, while females are around 99 cm (39 in) at that age. The ray can live up to 11 years, and full-grown sizes are around 120 cm (47 in) for males, and females reach 137 cm (54 in). They range from central California south to the Gulf of California. Morphological and genetic variations occur in the mitochondrial DNA in those found in the Gulf of California, evidencing their isolation from the rest. Because of this, the conservation of this species must be carefully managed to preserve the biological diversity. The shovelnose is considered to be a primitively developed ray, with many features of both sharks and rays.
The giant guitarfish, also known as the whitespotted wedgefish, is a large species of guitarfish in the family Rhinidae. It is restricted to the Red Sea, Persian Gulf, and western Indian Ocean, but was formerly considered more widespread due to confusion with its relatives.
The elegant stubfoot toad or Pacific jambato frog is a species of toad in the family Bufonidae found in lowlands and Andean slopes of northwest Ecuador to 1,140 m (3,740 ft) asl and on the Gorgona Island, off southwest coast of Colombia. It was described by George Albert Boulenger in 1882 based on a specimen collected by Edward Whymper. It is known in Spanish as rana jambato del Pacífico or simply jambato del Pacífico.
Pristimantis rosadoi is a species of frog in the family Strabomantidae. It is found in north-western Ecuador in Carchi, Esmeraldas, and Pichincha provinces, and in the adjacent Colombia in the Nariño Department as well as on the Gorgona Island; there is some doubt about the identity of the Gorgona Island specimens, while the checklist of Colombian amphibians only mentions the Gorgona record. The specific name rosadoi honors José P. O. Rosado, herpetologist at the Museum of Comparative Zoology, and also alludes to similarity of this species to Pristimantis roseus. Common name Rosado's robber frog has been proposed for it.
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.
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 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 Brazilian guitarfish is a species of fish in the family Rhinobatidae. It is endemic to Brazil, where its natural habitat is coastal waters on the continental shelf. This fish is viviparous and has a long gestation period, concluding with the birth of live pups in February. At this time the fish are subject to intense fishing activity but catches have been dwindling in recent years as a result of overfishing. Because so few breeding-size fish remain, the International Union for Conservation of Nature has assessed the fish's conservation status as being "critically endangered".
The ringstreaked guitarfish is a species of fish in the Rhinobatidae family found in China, Japan, South Korea, Taiwan, and Vietnam. Its natural habitats are open seas, shallow seas, coral reefs, and estuarine waters.
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 shortnose guitarfish is a species of fish in the Trygonorrhinidae family found in the southwest Atlantic in coastal parts near sandy sea floors of southern Brazil, through Uruguay, to northeast Argentina. It reaches a length of 66 cm (2.17 ft). Their diet consist of Crabs, worms, clams and small fishes. The guitarfish has become critically endangered because of the rapid decline caused by overfishing.
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 southern banded guitarfish, also known as the witch guitarfish, is a species of fish in the Trygonorrhinidae family found at reefs and other habitats from shallow water to a depth of 90 m (300 ft) in the tropical East Pacific. It ranges from Mazatlan, Mexico, to Colombia, but it likely also occurs off Ecuador and Peru.It is threatened by habitat loss. It is closely related to the more northernly distributed banded guitarfish.
Tarsistes philippii is a taxonomically dubious species of guitarfish, family Rhinobatidae. It is known only from a dried head from the Juan Fernández Islands off Chile. The head had a long, thin, flat snout, rounded at the tip like that of the goblin shark, and the underside covered with small stellate prickles except for the base. The head was covered with larger spinules, with six still larger ones forming a curve around the eye.
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 biodiversity of Colombia is the variety of indigenous organisms in the country with the second-highest biodiversity in the world. As of 2021, around 63,000 species are registered in Colombia, of which 14% are endemic. The country occupies worldwide the first position in number of orchids, birds and butterflies, second position in plants, amphibians and fresh water fish, third place in species of palm trees and reptiles and globally holds the sixth position in biodiversity of mammals.
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.
The Colombian white-faced capuchin, also known as the Colombian white-headed capuchin or Colombian white-throated capuchin, is a medium-sized New World monkey of the family Cebidae, subfamily Cebinae. It is native to the extreme eastern portion of Panama and the extreme north-western portion of South America in western Colombia and northwestern Ecuador.
The stripenose guitarfish is a species of fish in the Rhinobatidae family endemic to the eastern coast of India, and Sri Lanka. Its natural habitat is in the neritic zone.
