The Thresher Shark is also known as the Alopias Vulpinus or Fox Shark. Its name comes from the sharks unusually large tail (caudal fin), which is in most cases, as long as the shark itself!
Today, there are three living species of this Shark:
But experts are still puzzled about the possible existence of a fourth species. This mystery continues to elude enthusiasts, but many believe it’s only a matter of time before this fourth species is confirmed.
It’s origin is also surrounded by mystery. Most likely, the closer relative of the Fox Shark is the Megamouth Shark. Scientific studies are ongoing to try and resolve the many mysteries that surround this unusual and unique fish.
The largest known Thresher Sharks reach a length of more than 6 meters (20ft) and weigh 600 kilograms (216 pounds). Bigeye Threshers are normally the largest with Pelagic Threshers being the smallest.
These are slow growing sharks. They reach their maturity between 8 and 13 years old and live about 22 years. Again, there is quite a bit of mystery here. Some believe this shark is capable of living much longer, but simply hasn’t been verified.
