Rhynchobatus
''Rhynchobatus'' is a group of rays commonly known as wedgefishes in the family Rhinidae. They are found in the tropical and subtropical Indo-Pacific with a single species (''R. luebberti'') in the eastern Atlantic. All species in this genus are assessed as Vulnerable or Endangered by IUCN. The species are superficially similar and have often been confused. The various species can generally be separated by a combination of snout shape, vertebral count and exact colour (distribution of white spots, and presence/absence of a black spot at the base of the pectoral fin). The largest species can reach about and are among the largest species of rajiforms, but the smallest reach less than one-third of that size.Last, Kyne & Compagno (2016). A new species of wedgefish Rhynchobatus cooki (Rhinopristiformes, Rhinidae) from the Indo-West Pacific. Zootaxa 4139(2): 233-247.

Giant Guitarfish
The giant guitarfish (''Rhynchobatus djiddensis''), 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. Taxonomy and range The giant guitarfish was previously believed to range throughout a large part of the Indo-Pacific, but recent evidence has shown that it, as traditionally defined, actually was a species complex consisting of four different species. In addition to the giant guitarfish, this complex includes the white-spotted guitarfish, the broadnose wedgefish and possibly the smoothnose wedgefish. With these as separate species, the giant guitarfish has a relatively restricted range; it is found only in the Red Sea and Persian Gulf, and the western Indian Ocean as far south as South Africa. Ranging across the western Indian Ocean, it is common to misidentify the separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhynchobatus Cooki
The roughnose wedgefish (''Rhynchobatus cooki'') is a species of fish in the Rhinidae family. It is found in Indonesia (off Java) and Singapore. Its natural habitats are open seas, shallow seas, coral reefs, estuarine waters, and coastal saline lagoons. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... Despite having been known for more than a decade, it remained undescribed until 2016.Last, P.R., Ho, H.-C. & Chen, R.-R. (2013).

Peter Forsskål
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus. Early life Forsskål was born in Helsinki, now in Finland but then a part of Sweden, where his father, Finnish priest , was serving as a Lutheran clergyman, but the family migrated to Sweden in 1741 when the father was appointed to the parish of Tegelsmora in Uppland and the archdiocese of Uppsala. As was common at the time, he enrolled at Uppsala University at a young age in 1742, but returned home for some time and, after studies on his own, rematriculated in Uppsala in 1751, where he completed a theological degree the same year. Linnaeus's disciple In Uppsala Forsskål was one of the students of Linnaeus, but apparently also studied with the orientalist Carl Aurivillius, whose contacts with the Göttingen orientalist Johann David Michae ...
