Proscylliidae
The finback catsharks are a small family (biology), family, the Proscylliidae, of Carcharhiniformes, ground sharks. They can be found in warm seas worldwide and are often the most numerous and common shark in tropical regions. They are generally less than 1 m in length, and are slow-moving predators that feed on bony fish and small invertebrates. Although some bear live young, the majority lay eggs with almost fully developed young; these egg cases, known as Egg case (Chondrichthyes), "mermaid's purses", are unique in appearance to each species. Taxonomy Genus ''Proscyllium'' Franz Martin Hilgendorf, Hilgendorf 1904 * Graceful catshark (''Proscyllium habereri'') was first discovered by Hildendorf in 1901. * ''Proscyllium venustum'' is found in temperate regions. It is distributed along the Northwest Pacific, primarily Japan. These sharks are oviparous; they lay eggs in pairs in which the embryos feed solely on yolk. This species is considered harmless to humans. * Magnificent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Ribbontail Catshark
The pygmy ribbontail catshark (''Eridacnis radcliffei'') is a species of finback catshark, family Proscylliidae, distributed patchily in the western Indo-Pacific from Tanzania to the Philippines. It occurs around the edges of continental and insular shelves at a depth of , typically on or near mud bottoms. One of the smallest living shark species, the pygmy ribbontail catshark grows to a maximum known length of . It has a slender body with a low, ribbon-like tail fin, and is dark brown in color with blackish dorsal fin markings and tail bands. This shark feeds mainly on bony fishes, followed by crustaceans and then squid. It is aplacental viviparous with females bearing litters of 1–2 relatively large pups. It is of minimal significance to fisheries, being caught as bycatch in some areas. Taxonomy The first known specimens of the pygmy ribbontail catshark were collected during the 1907–1910 Philippine Expedition of the U.S. Fish Commission Steamer ''Albatross'' ...

African Ribbontail Catshark
The African ribbontail catshark, ''Eridacnis sinuans'', is a finback catshark of the family Proscylliidae, found in the western Indian Ocean, from Tanzania, South Africa, and Mozambique, at depths between 180 and 480 m. It can grow up to a length of 37 cm. The African ribbontail catshark is ovoviviparous Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a "bridging" form of reproduction between egg-laying oviparity, oviparous and live-bearing viviparity, viviparous reproduction. Ovoviviparous animals possess embryos that develo ... giving birth to two young per litter. The African ribbontail catshark's coloration is grey-brown.

Hugh McCormick Smith, also H. M. Smith (November 21, 1865 – September 28, 1941) was an American ichthyologist and administrator in the United States Bureau of Fisheries. Biography Smith was born in Washington, D.C. In 1888, he received a Doctor of Medicine from Georgetown University; then, in 1908, a Doctor of Law from the Dickinson School of Law at Dickinson College. He began working for the United States Fish Commission (formally, the United States Commission on Fish and Fisheries) in 1886 as an assistant. He directed the scientific research center there from 1897 to 1903. From 1901 to 1902, he directed the Marine Biological Laboratory at Woods Hole, Massachusetts. At the same time, he was on the faculty at Georgetown, teaching medicine from 1888 to 1902 and histology from 1895 to 1902. From 1907 to 1910, Smith led the scientific party aboard the U.S. Bureau of Fisheries (successor organization of the U.S. Fish Commission) research ship during her two-and-a-half-year exp ...

William Charles Schroeder (1895–1977) was an American ichthyologist. He was born on Staten Island, New York. He, along with his lifelong colleague Henry Bryant Bigelow, made substantial contributions to the knowledge of the fish fauna of the western North Atlantic. The two described 42 new species of jawless fishes and cartilaginous fishes, and authored several seminal publications, including ''Fishes of the Western North Atlantic'' and ''Fishes of the Gulf of Maine''.

James Smith (ichthyologist)
James Leonard Brierley Smith (26 September 1897 – 8 January 1968) was a South African ichthyologist, organic chemist, and university professor.

Early life Born in Graaff-Reinet, 26 September 1897, Smith was the elder of two sons of Joseph Smith and his wife, Emily Ann Beck. Educated at country schools at Noupoort, De Aar, and Aliwal North, he finally matriculated in 1914 from the Diocesan College, Rondebosch.

Shark Genera
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. Modern sharks are classified within the division Selachii and are the sister group to the Batomorphi ( rays and skates). Some sources extend the term "shark" as an informal category including extinct members of Chondrichthyes (cartilaginous fish) with a shark-like morphology, such as hybodonts. Shark-like chondrichthyans such as ''Cladoselache'' and ''Doliodus'' first appeared in the Devonian Period (419–359 million years), though some fossilized chondrichthyan-like scales are as old as the Ordovician, Late Ordovician (458–444 million years ago). The earliest confirmed modern sharks (Selachii) are known from the Early Jurassic around , with the oldest known member being ''Agaleus'', though records of true sharks may extend back as far as the Permian.
