AboutThe thresher shark spends most of its time in the deep waters of the open sea, rarely straying into coastal areas. To survive in these colder waters, they have evolved to be endothermic. This means that they can keep their body temperature higher than the temperature of the surrounding water. They do this through a specialised heat exchange system, which allows them to conserve heat produced through internal body mechanisms such as metabolism or muscle shivering.
How to identifyA large shark, with the "classic shark shape" - a torpedo-shaped body, large dorsal fin and large pectoral fins. The thresher shark is easily told from other sharks by the long upper lobe of the tail, which can be as long as the shark's body.
In our area
Thresher sharks are not common to the UK but are a migratory species and can be seen during the Summer months when the UK waters are at the warmest. Thresher sharks are normally found in deeper water away from land but if you're lucky you might be able to see a Thresher jump high from the water into the air!
