Thresher sharks are large lamniform sharks of the family Alopiidae found in all temperate and tropical oceans of the world; the family contains three extant species, all within the genus Alopias.

The common thresher (Alopias vulpinus), also known as Atlantic thresher, is the largest species of thresher shark, family Alopiidae, reaching some 6 m (20 ft) in length. About half of its length consists of the elongated upper lobe of its caudal fin. With a streamlined body, short pointed snout, and modestly sized eyes, the common thresher resembles (and has often been confused with) the pelagic thresher (A. pelagicus). It can be distinguished from the latter species by the white of its belly extending in a band over the bases of its pectoral fins. The common thresher is distributed worldwide in tropical and temperate waters, though it prefers cooler temperatures. It can be found both close to shore and in the open ocean, from the surface to a depth of 550 m (1,800 ft). It is seasonally migratory and spends summers at lower latitudes.

Thresher Shark

Thresher sharks are easily recognizable by their “weaponised” caudal fin, which can be as long as their body, up to 20 feet (6 meters). During a hunt, the sharks swim close to a school of fish and then abruptly break, which causes their caudal fin to flick over the body into the school, at an average speed of over 30 miles per hour, stunning and killing the fish. The Thresher can then eat at its leisure. (Source: wildfor.life)
