Cat Sharks
Catsharks are ground sharks of the family Scyliorhinidae. They are the largest family of sharks with around 160 species placed in 17 genera. 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 The family includes 17 genera and over 150 species, making it the largest family of sharks. * '' Akheilos'' White, Fahmi & Weigmann, 2019 * ''Apristurus'' Garman, 1913 * ''Asymbolus'' Whitley, 1939 * ''Atelomycterus'' Garman, 1913 * ''Aulohalaelurus'' Fowler, 1934 * ''Bythaelurus'' Compagno, 1988 * ''Cephaloscyllium'' T.

Haploblepharus
''Haploblepharus'' is a genus of catshark, and part of the family Scyliorhinidae, containing four species of shysharks. Their common name comes from a distinctive defensive behavior in which the shark curls into a circle and covers its eyes with its tail. The genus is endemic to southern Africa, inhabiting shallow coastal waters. All four species are small, stout-bodied sharks with broad, flattened heads and rounded snouts. They are characterized by very large nostrils with enlarged, triangular flaps of skin that reach the mouth, and deep grooves between the nostrils and the mouth. Shysharks are bottom-dwelling predators of bony fishes and invertebrates. They are oviparous, with the females laying egg capsules. These harmless sharks are of no commercial or recreational interest, though their highly limited distributions in heavily fished South African waters are of potential conservation concern. Taxonomy and phylogeny The genus ''Haploblepharus'' was created by American zoolog ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Galeus
''Galeus'' is a genus of catshark, belonging to the family Scyliorhinidae, commonly known as sawtail catsharks in reference to a distinctive saw-toothed crest of enlarged dermal denticles, found along the upper edges of their caudal fins. They are found in the Atlantic, the western and central Pacific, and the Gulf of California, inhabiting deep waters at or close to the sea floor. Members of this genus are rather small, slim sharks with firm bodies and thick, rough skin. Their heads are usually fairly long and pointed, and have large mouths with well-developed furrows at the corners. They have large pectoral and anal fins, and two similar dorsal fins placed well back. Many species are ornately patterned with dark saddles and/or blotches. Sawtail catsharks feed on various invertebrates and fishes, and may be either egg-laying or live-bearing. These harmless sharks are sometimes caught as bycatch but are of minimal commercial value. Taxonomy ''Galeus'', derived from the Greek ''g ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Figaro (genus)
''Figaro'' is a genus of catshark, and part of the family Scyliorhinidae. Until 2008, ''Figaro'' was generally considered to be a subgenus of ''Galeus'' (sawtail catsharks). The two known species are found off Australia, inhabiting deep, offshore waters on or near the bottom. ''Figaro'' contains small, slender, firm-bodied sharks that bear distinctive crests of enlarged, spiny dermal denticles along the dorsal and ventral edges of their short caudal fins. The caudal peduncle is relatively long, such as that the anal and caudal fins are some distance apart. In adult males, the inner margins of the pelvic fins are fused together to form a subtle "apron" over the claspers. ''F. boardmani'' is a predator of fishes, crustaceans, and cephalopods, and is oviparous; less is known about the ''F. striatus''. Both are harmless and are of no economic importance. Taxonomy ''Figaro'' was coined as a subgenus of ''Pristiurus'' by Australian ichthyologist Gilbert Percy Whitley in a 192 ...

William Charles Schroeder
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''.

He is the grandson of Henry Bryant (naturalist), Henry Bryant who was an American physician and natural history, naturalist. After graduating from Harvard in 1901, he began working with famed ichthyologist Alexander Agassiz. Bigelow accompanied Agassiz on several major marine science expeditions including one aboard the ''USS Albatross (1882), Albatross'' in 1907.

In 1911, Bigelow was elected a Fellow of the American Academy of Arts and Sciences. He helped found the Woods Hole Oceanographic Institution in 1930 and was its founding director. During his life he published more than one hundred papers and several books. He was a world-renowned expert on coelenterates and elasmobranchs.
