Hemiscyllium Hallstromi
The Papuan epaulette shark, ''Hemiscyllium hallstromi'', is a bamboo shark in the family (biology), family Hemiscylliidae found around southern Papua New Guinea, between latitudes 7th parallel south, 7° S and 10th parallel south, 10° S, and longitude 144th meridian east, 144° E and 146th meridian east, 146° E. Its length is up to 75 cm. Reproduction is oviparous. Etymology The shark is named in honor of philanthropist Edward Hallstrom (1886–1970), a trustee and chairman of Taronga Zoological Park, where holotype and paratype were kept alive in captivity.

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.

Oviparous
Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (i.e., by laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother. This is the reproductive method used by most animal species, as opposed to viviparous animals that develop the embryos internally and metabolically dependent on the maternal circulation, until the mother gives birth to live juveniles. Ovoviviparity is a special form of oviparity where the eggs are retained inside the mother (but still metabolically independent), and are carried internally until they hatch and eventually emerge outside as well-developed juveniles similar to viviparous animals. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or ...

Fish Of Papua New Guinea
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Fauna Of The Papuan Peninsula
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a book ...

Hemiscyllium
''Hemiscyllium'' is a genus of sharks in the family Hemiscylliidae. Overview Hemiscyllium sharks of the family Hemiscylliidae are also known as walking sharks and Epaulette sharks. These small, nocturnal, benthic dwelling swimmers have evolved to be able to 'walk', or use their fins to propel themselves over rocks, into pools, or into small crevices in their habitats. Research from the School of Biomedical Sciences at the University of Queensland in Australia has determined that this genus most recently split from the genus Chiloscyllium around 44 million years ago. 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 in the Seychelles.Debelius, H. (1993). ''Indian Ocean Tropical Fish Guide.'' Aquaprint Verlags GmbH. They have short snouts with nostrils placed almost at the tip, well-elevated eyes, and supraorbital ridges. The mouth is ...

Leonard Compagno
Leonard Joseph Victor Compagno (1943-2024) was an international authority on shark taxonomy and the author of many scientific papers and books on the subject, best known of which is his 1984 catalogue of shark species produced for the Food and Agriculture Organization (FAO) of the United Nations.

Carpet Shark
Carpet sharks are sharks classified in the order (biology), order Orectolobiformes . Sometimes the common name "carpet shark" (given because many species resemble ornately patterned carpets) is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae. Carpet sharks have five gill slits, two spineless dorsal fins, and a small mouth that does not extend past the eyes. Many species have barbel (anatomy), barbels. Characteristics The carpet sharks are a diverse group of sharks with differing sizes, appearances, diets, and habits. They first appeared in the fossil record in the Early Jurassic; the oldest known orectolobiform genera are ''Folipistrix'' (known from Toarcian to Aalenian of Belgium and Germany), ''Palaeobrachaelurus'' (Aalenian to Barremian) and ''Annea (fish), Annea'' (Toarcian to Bajocian of Europe). All species have two dorsal fins and a relatively short, transverse mouth that does not extend behind the eyes. Besides the nost ...

List Of Sharks
Shark is the naming term of all members of Selachimorpha suborder in the subclass Elasmobranchii, in the class Chondrichthyes. The Elasmobranchii also include rays and skates; the Chondrichthyes also include Chimaeras. The first shark-like chondrichthyans appeared in the oceans 400 million years ago, developing into the crown group of sharks by the Early Jurassic. Listed below are extant species of shark. Sharks are spread across 557 described and 23 undescribed species in eight orders. The families and genera within the orders are listed in alphabetical order.

Edward Hallstrom
Sir Edward John Lees Hallstrom (25 September 1886 – 27 February 1970) was one of Australia's best-known philanthropists and businessmen of the mid 20th century. Hallstrom is best known for his long association with the Taronga Zoo and for his "Silent Knight" brand of refrigerators. Early life and family background Born at High Park station, near Coonamble, New South Wales, Hallstrom was the eighth of a family of nine children born to William Hallstrom, a saddler from England of Sweden, Swedish extraction, and his Australian wife Mary Ann (née Colless). The accepted biographical narrative is that, at the age of four, his father's farm failed and the family moved to Waterloo, New South Wales, Waterloo, an inner-city suburb of Sydney. The actual events before the move were complicated. In 1888, Hallstrom's father had sued a neighbour concerning damage caused by a dam on the neighbour's property. Not long before he won £500 in damages, a suspicious fire destroyed a shed on h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bamboo Shark
The Hemiscylliidae are a family (biology), 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 barbel (anatomy), barbels and large Spiracle (vertebrates), 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 fin, pectora ...
