The sawsharks or saw sharks are an order (Pristiophoriformes) of sharks bearing long blade-like snouts edged with teeth, which they use to slash and disable their prey. There are five described (and four undescribed) species known, in a single family Pristiophoridae of two genera. Most occur in waters from South Africa to Australia and Japan, at depths of 40 m and below; in 1960 the Bahamas sawshark was discovered in the deeper waters (640 m to 915 m) of the northwestern Caribbean.

Orders Carcharhiniformes Heterodontiformes Hexanchiformes Lamniformes Orectolobiformes Pristiophoriformes Squaliformes Squatiniformes † Symmoriida Sharks (superorder Selachimorpha) are fish with a full cartilaginous skeleton [1] and a streamlined body. ... Year 1960 (MCMLX) was a leap year starting on Friday (link will display full calendar) of the Gregorian calendar. ... “West Indian” redirects here. ...

Sawsharks also have a pair of long barbels about halfway along the snout. They have two dorsal fins, but lack anal fins, and range up to 170 cm in length. Genus Pliotrema has six gill slits, and Pristiophorus the more usual five. The teeth of the saw typically alternate between large and small. This koi carp has two pairs of barbels, the second pair being quite small. ... Dorsal fin of an orca A dorsal fin is a fin located on the backs of fishes, whales, dolphins, and porpoises, as well as the (extinct) ichthyosaurs. ... Fish anatomy is primarily governed by the physical characteristics of water, which is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs light more than does air. ... Gill slits are gills with individual openings rather than a outer cover. ...

The sharks typically feed on bony fish, shrimp, squids, and crustaceans, depending on species. They cruise the bottom, using the barbels and ampullae of Lorenzini on the saw to detect prey in mud or sand, then hit victims with side-to-side swipes of the saw, crippling them. Subclasses Actinopterygii Sarcopterygii Osteichthyes are the bony fish, a group paraphyletic to the land vertebrates, which are sometimes included. ... Superfamilies Alpheoidea Atyoidea Bresilioidea Campylonotoidea Crangonoidea Galatheacaridoidea Nematocarcinoidea Oplophoroidea Palaemonoidea Pandaloidea Pasiphaeoidea Procaridoidea Processoidea Psalidopodoidea Stylodactyloidea True shrimp are swimming, decapod crustaceans classified in the infraorder Caridea, found widely around the world in both fresh and salt water. ... Suborders †Plesioteuthididae (incertae sedis) Myopsina Oegopsina Squid are a large, diverse group of marine cephalopods. ... For the Dutch band, see Crustacean (band). ... The ampullae of Lorenzini are special sensing organs, forming a network of jelly-filled canals found on elasmobranchs (sharks and rays) and Chimaera. ...

Most of the species are fished commercially, and their meat is considered to be of excellent quality. Japanese sawshark is used to make kamaboko, a traditional type of fishcake. Bold textMason Struthers (Japanese Kanji: ?) is a variety of Japanese processed seafood products, called surimi, in which various white fish are pureed, formed into distinctive loaves, and then steamed until fully cooked and firm in texture. ... A fishcake (also fish cake) is a food item similar to a rissole or croquette, consisting of a filleted fish and potato patty coated in breadcrumbs or batter, and fried. ...

Although they are similar in appearance, sawsharks are distinct from sawfish. Sawfish have a much larger maximum size, lack barbels, have evenly sized rather than alternating sawteeth, and have gill slits on their undersurface rather than on the side of the head.
