Naming
The genus and family name derive from the Greek word alopex, meaning fox. Indeed the long-tailed thresher shark, Alopias vulpinus, is named the fox shark by some authorities. A fox is a member of any of 27 species of small omnivorous canids. ...
Distribution and habitat Although occasionally sighted in shallow, inshore waters, thresher sharks are primarily pelagic; they prefer the open ocean, staying within the first 500 m of the water column. They are also found in coastal waters over continental shelves. Diagram of the layers of the pelagic zone. ...

Anatomy and appearance Named for and easily recognised by their exceptionally long, thresher-like tail or caudal fins (which account for 50 percent of their total body length), thresher sharks are active predators; the tail is actually used as a weapon to stun prey. By far the largest of the three species is the thintail thresher, Alopias vulpinus, which may reach a length of 7.6 m (25 ft) and a weight of 348 kg (767 lb). The bigeye thresher, Alopias superciliosus, is next in size, reaching a length of 4.9 m (16 ft); at just 3 m (10 ft), the pelagic thresher, Alopias pelagicus, is the smallest.

A thresher is a device that first separates the head of a stalk of grain from the straw, and then further separates the kernel from the rest of the head. ...
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. ...

Thresher sharks are fairly slender, with small dorsal fins and large, recurved pectoral fins. With the exception of the bigeye thresher, these sharks have relatively small eyes. Coloration ranges from brownish, bluish or purplish gray dorsally with lighter shades ventrally.
Diet Pelagic schooling fish (such as bluefish, juvenile tuna, and mackerel), squid and cuttlefish are the primary food items of the thresher sharks. They are known to follow large schools of fish into shallow waters. Crustaceans and the odd seabird are also taken. The Guppy (Poecilia reticulata) is one of the most popular freshwater aquarium fish species in the world. ...

Behaviour Thresher sharks are solitary creatures which keep to themselves. It is known that thresher populations of the Indian Ocean are separated by depth and space according to gender. All species are noted for their highly migratory or oceanodromous habits. Many types of fish undertake migrations on a regular basis, on time scales ranging from daily to annual, and with distances ranging from a few meters to thousands of kilometers. ...
Reproduction No distinct breeding season is observed by thresher sharks. Fertilization and embryonic development occur internally; this ovoviviparous or live-bearing mode of reproduction results in a small litter (usually 2 to 4) of large well-developed pups, up to 150 cm at birth in thintail threshers. The young fish exhaust their yolk sacs while still inside the mother, at which time they begin feeding on the mother's unfertilized eggs; this is known as oophagy. Ovoviviparous animals develop within eggs that remain within the mothers body up until they hatch or are about to. ...
Oophagy (egg eating) is the practice of embryos feeding on eggs produced by the ovary while still inside the mothers uterus. ...
Thresher sharks are slow to mature, males reaching sexual maturity between 7 and 13 years of age and females between 8 and 14 years in bigeye threshers. They may live for 20 years or more.
Thresher sharks are one of the few shark species known to jump fully out of the water making turns like dolphins, this behaviour is called breaching. Genera See article below. ...

Importance to humans Like all large sharks, threshers are slow growing and are therefore threatened by commercial fisheries. Other than for its meat, the sharks are hunted for their liver oil, skin (for leather), and their fins, for use in shark-fin soup.

They do not appear to be a threat to humans, although some divers have been hit with the upper tail lobe. There is an unconfirmed account of a fisherman being decapitated by a tail swipe as the shark breached.
