Ground Sharks
Carcharhiniformes ( from Classical Greek ' (karcharos) 'sharp/jagged' and ' (rhinos) 'nose', plus Latin ''forme'' 'shape'), commonly known as ground sharks, are the largest order of sharks, with over 270 species. They include a number of common types, such as Scyliorhinidae, catsharks, swellsharks, and Requiem shark, requiem sharks. Members of this order are characterized by the presence of a nictitating membrane over the eye, two dorsal fins, an anal fin, and five gill slits. The families in the order Carcharhiniformes are expected to be revised; recent DNA studies show that some of the conventional groups are not monophyletic. The oldest members of the order appeared during the Middle-Late Jurassic, which have teeth and body forms that are morphologically similar to living Scyliorhinidae, catsharks. Carchariniformes first underwent major diversification during the Late Cretaceous, initially as mostly small-sized forms, before radiating into medium and large body sizes during ...

Finetooth Shark
The finetooth shark (''Carcharhinus isodon'') is a species of requiem shark, in the family (biology), family Carcharhinidae, found in the western Atlantic Ocean, from North Carolina to Brazil. It forms large Shoaling and schooling, schools in shallow, coastal waters, and fish migration, migrates seasonally following warm water. A relatively small, slender-bodied shark, the finetooth shark can be identified by its needle-like teeth, dark blue-gray Anatomical terms of location#Dorsal and ventral, dorsal coloration, and long gill slits. It attains a maximum length of 1.9 m (6.2 ft). The diet of this species consists primarily of small bony fishes, in particular menhaden. Like other members of its family, it is viviparous with females giving birth to two to six pups in estuary, estuarine nursery areas every other year. Valued for its meat, the finetooth shark forms an important component of the commercial fishing, commercial gillnet shark fishery operating off the southeast ...

Eschmeyer's Catalog Of Fishes
Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase, which involves cross-references to the Catalog's information for all accepted taxa. the searchable catalogue contains entries for about 58,300 fish species names, about 33,400 of which are currently accepted (valid), and for some 10,600 genera (5,100 valid).

Gavin J
Gavin is a Celtic male given name. It is the Scottish variation of the medieval Welsh name Gawain, meaning 'God send' or 'white hawk/falcon'. Sir Gawain is a knight of King Arthur's Round Table. '' Sir Gawain and the Green Knight'' is an epic poem in which he beheads the Green Knight, who promptly replaces his head and threatens Gawain an identical fate the same time next year. Decapitation figures elsewhere: the Italian (and originally Sardinian) name Gavino is the name of an early Christian martyr ( San Gavino, Porto Torres, Sardinia) who was beheaded in 300 AD, his head being thrown in the Mediterranean Sea, later recovered and interred with his body.

William Toby White
William Toby White is an Australian ichthyologist. He studies speciation and biodiversity of shark, ray, and skate species (subclass Elasmobranchii) through morphological and molecular systematics. Education White received bachelor's (1997) and doctoral (2003) degrees in Biological Science from Murdoch University in Perth, Australia. His doctoral thesis, "Aspects of the biology of elasmobranchs in a subtropical embayment in Western Australia and of chondrichthyan fisheries in Indonesia", examined 1) spatial partitioning of food resources available to shark, ray, and skate species in Shark Bay (off the western coast of Australia), and 2) the relative frequencies of shark, ray, and skate species caught in fisheries off the coast of southeastern Indonesia. From 2004 to 2006 he did post-doctoral training, also at Murdoch University. Professional career Since 2006, White has served as ichthyologist at the Australian National Fish Collection which is part of the CSIRO Marine ...

Dichichthyidae
''Dichichthys'' is a genus of sharks which is the only genus in the monotypic family Dichichthyidae, the bristle sharks. These sharks are found in the Western Pacific Ocean. Until recently, scientists believed these 5 species were part of the genus ''Parmaturus,'' until morphological testing confirmed its placement in its own family. Supraorbital crests on the chondrocranium also distinguish ''Dichichthys'' from other catshark genera/families. Species ''Dichichthys'' contains the following five recognised valid species: * '' Dichichthys albimarginatus'' ( Séret & Last, 2007) (Whitetip bristle shark) * '' Dichichthys bigus'' (Séret & Last, 2007) (Beige bristle shark) * '' Dichichthys melanobranchus'' (W. L. Chan, 1966) (Blackgill catshark) * '' Dichichthys nigripalatum'' (Fahmi & Ebert, 2018) (Indonesian filetail catshark) * '' Dichichthys satoi'' (White, Stewart, O'Neill The O'Neill dynasty ( Irish: ''Ó Néill'') are a lineage of Irish Gaelic origin that held prominent ...
