Introducing Thresher Sharks! Imagine seeing a shark with a long tail that can be as long as the total body length. Thresher Sharks can only be consistently spotted in a few places in the world, so when was in the Philippines I had to see them up close.
In this post I’ll cover why thresher sharks have such long tails, what thresher sharks eat, how big thresher sharks typically are, and where to find thresher sharks, in addition to showing some videos of threshers in motion. I’ll also detail my specific experience SCUBA diving to see thresher sharks at the bottom of this page as well.
Thresher sharks are mostly known for the size of their tail (“upper caudal fin lobe”), which is typically equal to the length of the rest of their body! Check out this below photo:
Why do Thresher Sharks have large tails? Thresher sharks are active predators – they use their huge tails not only to swim, but also to swat and stun much smaller prey fish. Whack! When hunting schooling fish, thresher sharks are known to “slap” the water, herding and stunning prey.
