Urogymnus Natalensis
''Urogymnus'' is a genus of stingrays in the family Dasyatidae from marine, brackish and freshwater habitats in the Indo-Pacific and tropical East Atlantic regions. The genus was previously considered to be monotypic, containing only the porcupine ray (''U. asperrimus'').

Porcupine Ray
The porcupine ray (''Urogymnus asperrimus'') is a rare species of stingray in the family (biology), family Dasyatidae. This benthic fish, bottom-dweller is found throughout the tropical Indo-Pacific, as well as off West Africa. It favors sand, coral rubble, and seagrass habitats in inshore waters to a depth of . A large and heavy-bodied species reaching in width, the porcupine ray has a nearly circular, plain-colored pectoral fin disc and a thin tail without any fin folds. Uniquely within its family, it lacks a venomous stinging spine. However, an adult ray can still defend itself ably with the many large, sharp thorns found over its disc and tail. The diet of the porcupine ray consists mainly of benthic invertebrates and bony fishes, which it digs up from the sea floor. It is aplacental viviparous, in which the developing embryos are nourished by histotroph ("uterine milk") produced by the mother. The porcupine ray has long been valued for its rough and durable skin, which was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Freshwater Stingray
The giant freshwater stingray (''Urogymnus polylepis'', also widely known by the junior synonym ''Himantura chaophraya'') is a species of stingray in the family Dasyatidae. It is found in large rivers and estuaries in Southeast Asia and Borneo, though historically it may have been more widely distributed in South and Southeast Asia. The largest freshwater fish and the largest stingray in the world, this species grows up to across and can reach up to in weight. It has a relatively thin, oval pectoral fin disc that is widest anteriorly, and a sharply pointed snout with a protruding tip. Its tail is thin and whip-like, and lacks fin folds. This species is uniformly grayish brown above and white below; the underside of the pectoral and pelvic fins bear distinctive wide, dark bands on their posterior margins. Bottom-dwelling in nature, the giant freshwater stingray inhabits sandy or muddy areas and preys on small fishes and invertebrates. Females give live birth to litters of one ...

Tubemouth Whipray
The tubemouth whipray (''Urogymnus lobistoma'') is a little-known species of Myliobatiformes, stingray in the family (biology), family Dasyatidae, named for its distinctive, highly protrusible jaws. It is found in shallow, brackish water near mangrove forests and large river mouths along the coasts of southwestern Borneo and southern Sumatra. Measuring up to across, this species has a diamond-shaped pectoral fin disc with an elongated, pointed snout and broadly rounded outer corners. The upper surface of the disc is a plain grayish or brownish in color, and covered by small, flattened dermal denticles. The tubemouth whipray is relatively common at present, but is heavily pressured by habitat degradation and coastal fisheries. The International Union for Conservation of Nature (IUCN) has listed it as Vulnerable species, Vulnerable. Taxonomy The first known specimens of the tubemouth whipray were caught from the South China Sea in 1999, and initially thought to be ''Smalleye whip r ...

William John Macleay
Sir William John Macleay (13 June 1820 – 7 December 1891) was a Scottish-Australian politician, Natural history, naturalist, zoologist, and Herpetology, herpetologist. Early life Macleay was born at Wick, Highland, Wick, Caithness, Scotland, second son of Kenneth Macleay of Keiss and his wife Barbara, ''née'' Horne. Macleay was educated at the Edinburgh Academy 1834–36 and then to studied medicine at the University of Edinburgh; but when he was 18 years old his widowed mother died, and he decided to go to Australia with his cousin, William Sharp MacLeay. They arrived at Sydney in March 1839 on HMS Royal George (1827), HMS ''Royal George''.

Mangrove Whipray
The mangrove whipray (''Urogymnus granulatus'') or whitetail stingray, is a species of stingray in the family (biology), family Dasyatidae. It is widely distributed in the Indo-Pacific region from the Red Sea to northern Australia and Micronesia. A benthic fish, benthic inhabitant of shallow inshore waters, juvenile mangrove whiprays favor mangrove and estuary, estuarine habitats, while adults favor sandy to rocky areas in lagoons and coral reefs. This species can be identified by its thick, oval pectoral fin disc that is dark gray above with numerous white flecks, and by its relatively short, whip-like tail that is white past the stinging spine. It grows up to across. Solitary in nature, the mangrove whipray preys mainly on small, benthic, bottom-dwelling bony fishes and invertebrates. It is, like other stingrays, aplacental viviparous, with the females nourishing their unborn young via histotroph ("uterine milk"). The mangrove whipray is caught for its meat, shagreen, skin, an ...
