Nonetheless, the white, tiger and bull sharks are the “Big Three” in the shark attack world because they are large species that are capable of inflicting serious injuries to a victim, are commonly found in areas where humans enter the water, and have teeth designed to shear rather than hold.

The great white is the most dangerous shark with a recorded 314 unprovoked attacks on humans. This is followed by the striped tiger shark with 111 attacks, bull sharks with 100 attacks and blacktip shark with 29 attacks.

Out of more than 489 shark species, only three are responsible for a double-digit number of fatal, unprovoked attacks on humans: the great white, tiger, and bull. The oceanic whitetip has probably killed many more castaways, but these are not recorded in the statistics.

The top halves of their scythe-like tail fins are so huge that they can be as long as the rest of the shark. For around a century, people have been saying that the threshers lash out at their prey with these distended fins—hence the name.

Sometimes the thresher shark will slice the fish in half before eating. Thresher sharks are one of the few shark species known to jump fully out of the water, using their elongated tail to propel them out of the water, making turns like dolphins; this behavior is called breaching.

These sharks’ teeth are small, curved, smooth and razor sharp. Their teeth are similarly shaped in both the upper and lower jaws. Thresher sharks’ color varies from metallic brown to blue on their dorsal (upper) sides and white on their ventral (under) sides.

Thresher Sharks are an incredibly unique species of shark. They have very unusual anatomy, behaviors, and history. There May Be An Undiscovered Species Of Thresher Sharks: So far, scientists recognize three extant species of Thresher Shark: The Pelagic Thresher, Bigeye Thresher, and the Common Thresher.

Danger to Humans The thresher shark is considered harmless. The species is shy and difficult to approach. Divers that have encountered these sharks claim that they did not act aggressively. However, some caution should be taking considering the size of these sharks.

Myth #1: Sharks Must Swim Constantly, or They Die This allows them to rest on the sea floor and still breathe. Sharks, on the other hand, do not have a swim bladder. Instead, they rely on lift generated by their large pectoral fins, much like the way an airplane’s wings provide lift in the air.

What a Thresher Shark Looks Like. Thresher sharks have big eyes, a small mouth, large pectoral fins, first dorsal fin, and pelvic fins. They have a small second dorsal fin (near their tail) and anal fins. They have light gray to white coloring below their pectoral fins.
