Hemiscyllium Sp
''Hemiscyllium'' is a genus of sharks in the family Hemiscylliidae. Overview This genus is confined to tropical waters off Australia, Papua New Guinea, and Indonesia, but an individual from this genus, possibly representing an undescribed species, has been photographed at the Seychelles. They have short snouts with the nostrils placed almost at the tip, and well-elevated eyes and supraorbital ridges. The mouth is closer to the tip of the snout than the eyes, and lacks the connecting dermal fold across the chin. The pectoral and pelvic fins are thick and heavily muscular. Either a black hood on the head or a large black spot on the sides of the body is present, though juveniles often are strongly marked with dark spots/bars. Some species are known as "walking sharks". In January 2020, marine biologists at the School of Biomedical Sciences at the University of Queensland in Australia announced new findings that provide evidence that genus ''Hemiscyllium'', also known as "walking ...

Hemiscylliidae
The Hemiscylliidae are a family of sharks in the order Orectolobiformes, commonly known as longtail carpet sharks and sometimes as bamboo sharks. They are found in shallow waters of the tropical Indo-Pacific. They are relatively small sharks, with the largest species reaching no more than in adult body length. They have elongated, cylindrical bodies, with short barbels and large spiracles. As their common name suggests, they have unusually long tails, which exceed the length of the rest of their bodies. They are sluggish fish, feeding on bottom-dwelling invertebrates and smaller fish. Genera and species ''Chiloscyllium'' This genus is distinguished by a relatively long snout with subterminal nostrils. The eyes and supraorbital ridges are hardly elevated. The mouth is closer to the eyes than to the tip of the snout, with lower labial folds usually connected across the chin by a flap of skin. The pectoral and pelvic fins are thin and not very muscular. No black hood on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert Percy Whitley
Gilbert Percy Whitley (9 June 1903 – 18 July 1975) was a British-born Australian ichthyologist and malacologist who was Curator of Fishes at the Australian Museum in Sydney for about 40 years. He was born at Swaythling, Southampton, England, and was educated at King Edward VI School, Southampton and the Royal Naval College, Osborne. Whitley migrated with his family to Sydney in 1921 and he joined the staff of the Australian Museum in 1922 while studying zoology at Sydney Technical College and the University of Sydney. In 1925 he was formally appointed Ichthyologist (later Curator of Fishes) at the Museum, a position he held until retirement in 1964. During his term of office he doubled the size of the ichthyological collection to 37,000 specimens through many collecting expeditions. Whitley was also a major force in the Royal Zoological Society of New South Wales, of which he was made a Fellow in 1934 and where he served as president during 1940–41, 1959–60 and 1973–74. ...

Taxa Named By Johannes Peter Müller
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shark Genera
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwat ...

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. He studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mouth of the Coppermine River. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pierre Joseph Bonnaterre
Abbé Pierre Joseph Bonnaterre (1752, Aveyron – 20 September 1804, Saint-Geniez-d'Olt) was a French zoology, zoologist who contributed sections on cetaceans, mammals, birds, reptiles, amphibians, fish, and insects to the ''Tableau encyclopédique et méthodique''. He is also notable as the first scientist to study the feral child Victor of Aveyron. Bonnaterre is credited with identifying about 25 new species of fish, and assembled illustrations of about 400 in his encyclopedia work of book. He was the first scientist to study Victor, the wild child of Aveyron, whose life inspired François Truffaut for his film ''The Wild Child''.

Hemiscyllium Ocellatum
The epaulette shark (''Hemiscyllium ocellatum'') is a species of longtailed carpet shark, family Hemiscylliidae, found in shallow, tropical waters off Australia and New Guinea (and possibly elsewhere). The common name of this shark comes from the very large, white-margined black spot behind each pectoral fin, which are reminiscent of military epaulettes. A small species usually under long, the epaulette shark has a slender body with a short head and broad, paddle-shaped paired fins. The caudal peduncle (to which the tail fin is attached) comprises over half the shark's length. Adults are light brown above, with scattered darker spots and indistinct saddles. Epaulette sharks have nocturnal habits and frequent shallow water on coral reefs or in tidal pools. This shark has evolved to cope with the severe night time oxygen depletion (hypoxia) in isolated tidal pools by increasing the blood supply to its brain and selectively shutting down non-essential neural functions. It is cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
