Whitetip Weasel Shark
The whitetip weasel shark ''(Paragaleus leucolomatus)'' is a weasel shark of the family Hemigaleidae. Only one specimen, caught off Kosi Bay, South Africa, has been caught. That specimen was 96 cm long. In 2020, a fuzzy image believed to be this shark was obtained on the show Extinct or Alive. The reproduction of this shark is viviparous Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the ....

Weasel Shark
The weasel sharks are a family, the Hemigaleidae, of ground sharks found from the eastern Atlantic Ocean to the continental Indo-Pacific. They are found in shallow coastal waters to a depth of . Most species are small, reaching no more than long, though the snaggletooth shark (''Hemipristis elongatus'') may reach . They have horizontally oval eyes, small spiracles, and precaudal pits. Two dorsal fins occur with the base of the first placed well forward of the pelvic fins. The caudal fin has a strong ventral lobe and undulations on the dorsal lobe margin. They feed on a variety of small bony fishes and invertebrates; at least two species specialize on cephalopods. They are not known to have attacked people. Genera and species The eight known species in this family are placed in four genera. ''Hemipristis'' is placed in the subfamily Hemipristinae, while ''Chaenogaleus'', ''Hemigaleus'', and ''Paragaleus'' are placed in the subfamily Hemigaleinae.Haaramo, M. (2005)Hemigaleidae - ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Kosi Bay
Kosi Bay is a series of four interlinked lakes in the Maputaland area of KwaZulu-Natal, South Africa. Ecology The lakes form part of the iSimangaliso Wetland Park, a UNESCO World Heritage Site. The closest town is Manguzi, some away from it. Kosi Bay estuary is only from the Mozambique border. It is possible to walk from the estuary to Ponta do Ouro in only an hour or so. It is one of the quietest beaches in South Africa. The Kosi River Mouth is known as "the aquarium" because of the clarity of the water and the abundance of fish species. Bird species in the area include the palm-nut vulture, Pel's fishing owl, white-backed night-heron, and kingfishers. Duiker, hippopotamus, crocodiles and bull sharks are also present, and loggerhead and endangered leatherback sea turtles lay their eggs on the beach. The Bay is noted for its aggressive bull shark population. The sharks are locally known as zambesi. Whale sharks and manta rays also visit the area. Whale watching to target ma ...

Extinct Or Alive
''Extinct or Alive'' is an American wildlife documentary television programme produced for Animal Planet by Hot Snakes Media of New York City, the United States. It is hosted by conservationist and television personality Forrest Galante, who travels to different locations around the globe to learn about possibly extinct animals and whether or not there is a chance that they may still be extant. The series has been involved in the possible rediscovery of eleven animals, namely the Zanzibar leopard, the Pondicherry shark, the Fernandina Island Galápagos tortoise, the Miller's grizzled langur, the Cape lion, the Malagasy hippopotamus, the Yangtze giant softshell turtle, Rio Apaporis caiman, Whitetip weasel shark, Ornate sleeper-ray and the Flapnose houndshark.

Viviparous
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients by oophagy ...

Paragaleus
''Paragaleus'' is a genus of weasel shark in the family Hemigaleidae. This genus has a rounded or slightly pointed snout, short gill slits, and a broadly arched mouth.

Known fossil species include '' P. pulchellus'' and '' P. antunesi''. * Whitetip weasel shark (''Paragaleus leucolomatus'') Compagno & Smale, 1985 (whitetip weasel shark* Atlantic weasel shark (''Paragaleus pectoralis'') (Garman Garman is a surname or first name.
