Thresher Shark Facts

 

  • First of all, the amazing Thresher Shark has a distinctly unique physical appearance that makes it easily recognizable. This holds true because their caudal fin grows to lengths proportionately far greater than other species of shark. In fact, it often attains virtually the same length as the body itself!
  • In addition, marine biologists suspect the possibility of the existence of a fourth species of Thresher Shark.  Yet they remain uncertain, due to a lack of sufficient evidence. So far only one specimen has been discovered, thus scientists cannot officially confirm the existence of a fourth species.
  • As members of the Lamniforme order, their body temperature remains higher than the water around them. This separates them from the great majority of other sharks. Finally, the three species in this genus include the Pelagic Thresher, the Bigeye Thresher, and the Common Thresher. The IUCN lists all three as Vulnerable.

Thresher Shark Physical Description

While the three known distinct species of Thresher Shark vary slightly in appearance, their general appearance remains the same. The different species range in maximum length from 10 ft (3 m) to 20 ft (6.1 m). Maximum weights for the different species vary, with the largest reaching 1,100 lb (500 kg). Color also varies, and includes gray, brown, blue,and even purplish! While the caudal fin grows large, the head remains relatively short, and the nose presents as somewhat cone-shaped. Furthermore, both the mouth and teeth remain relatively small. Yet the oversized caudal fin ranks as the most noteworthy physical characteristic of the species.

Thresher Shark Distribution, Habitat, and Ecology

First of all, it must be noted that the Thresher Shark inhabits all temperate and tropical oceans. Yet within that range, they generally only inhabit a specific portion of the ocean. Only occasionally will they venture into shallow waters near shore, usually in search of prey. That’s because they generally inhabit the pelagic zone of their area of ocean. Regions far from shore, and extending no deeper than 1,600 ft (500 m) comprise their typical habitat. This species primarily preys on such creatures as bluefish, squid, mackerel, and cuttlefish. Yet they will occasionally consume crustaceans and even seabirds. They often employ their enormous caudal fin to stun their prey by slapping the surface of the water. They live primarily solitary lives, yet will sometimes form small groups for hunting.
