About Thresher Sharks

Scientific Name: Alopias

Thresher Sharks are found more in the open sea as they prefer deeper waters for better hunting opportunities and tend to stray away from the coastal waters close to Cornwall. In deeper waters they herd smaller shoaling fish into a tight circle, then swim at high speeds and thrash their tail like a whip, stunning the fish and making them easy targets. Thresher Sharks have evolved to survive in colder waters, using endothermy – generating their own body heat with a specialised system of heat exchange. For more fun Thresher shark facts, read on…

How often do you see Thresher Shark on a boat trip?

Book a boat trip and you might get lucky to see one of these fantastic creatures in our Cornish waters.

Experience our boat trips and keep your eyes open and you might just get lucky.
