White Ghost Catshark
The white ghost catshark (''Apristurus aphyodes'') is a shark of the catshark family Pentanchidae, the deepwater catsharks. This shark is found in deep water in the northeast Atlantic between latitudes 57°N and 58°N. A deep-water catshark known from the eastern North Atlantic from depths of 1,014 to 1,800 m, it is known from only a limited number of specimens. It reaches a maximum of 54 cm or 1.7 ft total length which is a medium size for the ''Apristurus'' genus. Description and morphology The white ghost catshark has a slender and cylindrical body with a relatively long and flattened snout. It is distinguished from the other 10 North Atlantic ''Apristurus'' species by the following. It has a uniform whitish coloration and large oval eyes with a weak subocular fold. Its snout is bell shaped and contains numerous visible pores making up ampullae of Lorenzini on the dorsal and ventral side of the snout. Its preorbital snout length (where the snout intersects its e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Apristurus Albisoma
The white-bodied catshark (''Apristurus albisoma'') is a catshark of the family Pentanchidae, the deepwater catsharks. Description This shark is coloured whitish to light grey. Distribution This species is found in the western Pacific. The area of occupancy of this small benthic endemic shark was presumed very limited (less than 2,000 km²), being restricted to a narrow depth band on insular and seamount slopes near New Caledonia. However this species has been collected in waters of the north of New Zealand on the West Norfolk Ridge. Conservation status Although this species has been classified by the International Union for Conservation of Nature as of least concern, there is a worry that this species may be taken as un-utilised bycatch by deepwater trawl fisheries and that, like other deepwater species, it may not be sufficiently fecund to withstand exploitation pressure in these fisheries. The New Zealand Department of Conservation has classified the white-bod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smallbelly Catshark
The smallbelly catshark (''Apristurus indicus'') is a shark of the family Pentanchidae, the deepwater catsharks. This species is found in the western Indian Ocean near Somalia, the Gulf of Aden, and Oman, at depths between 1,300 and 1,840 m. Its length is up to 34 cm, although this measurement is of an immature specimen. The smallbelly catshark is not well known. It is found on continental slopes, and is probably caught by bottom trawlers. The reproduction of the smallbelly catshark is 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 kno ....

Pinocchio Catshark
The Pinocchio catshark (''Apristurus australis'') is a species of catshark in the family Pentanchidae, the deepwater catsharks. This species is found in Australia and possibly New Zealand. Its natural habitat is the open seas. It belongs to a genus of poorly known deep-water sharks. Very little is known of its biology. Possibly a widely distributed deep-water catshark found along the Australian continental slope at depths of 590 to 1,000 m, it consists of several distinct populations which may be separate species. Although part of the distribution includes heavily fished areas, particularly off southeastern Australia, much of its range is in unfished areas. Given the taxonomic uncertainty of the separate populations, it is not possible to assess the conservation status of this species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reprod ...

Bighead Catshark
The bighead catshark (''Apristurus bucephalus'') is a species of fish in the family Pentanchidae, the deepwater catsharks. This species is endemic to Australia. Its natural habitat is the open seas. It belongs to a genus of poorly known deep-water catsharks, and is recorded from only three specimens taken off Perth, Western Australia. This species could be rare or uncommon, and the effects of fisheries are unknown, though if its biology is like other deep-water shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ribless endoskeleton, dermal denticles, five to seven gill slits on each side, and pectoral fins that are not fused to the head.

Scyliorhinidae
Scyliorhinidae is a Family (biology), family of sharks, one of a few families whose members share the common name catsharks, belonging to the Order (biology), order Carcharhiniformes, the ground sharks. Although they are generally known as catsharks, some species can also be called dogfish due to previous naming. However, a dogfish may generally be distinguished from a catshark as catsharks lay eggs while dogfish have live young. Like most bottom feeders, catsharks feed on benthic invertebrates and smaller fish. They are not harmful to humans. The family is paraphyletic, containing several distinct lineages that do not form a monophyletic group. Genera Scyliorhinidae includes the following genera: * ''Cephaloscyllium'' Theodore Gill, T. N. Gill, 1862 * ''Poroderma'' Andrew Smith (zoologist), A. Smith, 1838 * ''Scyliorhinus'' Henri Marie Ducrotay de Blainville, Blainville, 1816 Anatomy and appearance Scyliorhinidae catsharks may be distinguished by their elongated, cat- ...

Stewart Springer
Stewart Springer (5 June 190623 August 1991) was an American ichthyologist and herpetologist. He was an expert on shark behavior, classification (taxonomy), and population distribution. More than 35 species of sharks, skates, rays, and other creatures are either classified by or named after him. Education Springer was a field naturalist, mostly self-taught. In 1964, 35 years after he dropped out of Butler University, Springer obtained a baccalaureate from George Washington University after having already achieved success in his chosen field of ichthyology. His interest in animal behavior was apparent early in his life, when at age 22, he identified and described a new species of lizard, '' Cnemidophorus velox'', the plateau striped whiptail. His interest in the whiptail was piqued, he said, by the fact that he was chaperoning a field trip with the Cottonwood Gulch Foundation in Arizona in 1928. His young team of Boy Scouts could catch jack rabbits and other lizards in the are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
