Sharks -What is the most dangerous shark on earth?
Which shark has evolved most efficiently to attack? Which has the sharpest teeth and strongest jaws? Where do they patrol? How do they attack? What is the world’s most dangerous shark? For 400 million years sharks have dominated the earth’s oceans. They have survived five planetary mass extinctions to become the top predators of the sea, honed to an evolutionary perfection. But what shark species is the most deadly? And where in the world is it least safe to venture into the water? We travel across the world from Australia to California to find out.

About Video
For 400 million years, sharks have dominated the Earth’s oceans. They have survived 5 planetary mass extinctions to become the top predators of the sea, honed to an evolutionary perfection. But what shark species is the most deadly? And where in the world is it least safe to venture into the water? Naked Science travelled across the world from Australia to California to find out.
There are over 400 species of shark, yet only 30 of these have been involved in unprovoked attacks on humans. Shark scientist John McCosker leads us through the basement of the Steinhart Aquarium to the ‘sharkophagus’, a coffin packed with pickled sharks. Naked Science compares the physiology of the great white, tiger and bull shark – the species big enough to mistake a human for prey.
In 2004, Australian surfer Bradley Smith became another statistic on the International Shark Attack File after he was disembowelled by a great white. In 2002, Hawaiian thirteen year old Bethany Hamilton had her arm severed below the shoulder by a tiger shark. In 2000, American high school coach Chuck Anderson lost his lower arm to a bull shark. But Naked Science demonstrates that the statistics may not be the most reliable measure of danger.
Only 2 miles from Honolulu’s beaches, Naked Science catches 10 tiger sharks. With an endoscope, we look inside a live tiger shark stomach. Kim Holland, marine biologist, takes us to Coconut Island to learn more about what he calls the ‘wolves of the sea’. Off the coast of Cape Town, white sharks breach up to 9ft out of the water. Naked Science catches these white shark attacks on film. Shark scientist Ryan Johnson takes us above and below the water, and calculates the speed white sharks erupt from the water. The tourist packed coasts of Florida are home to bull sharks, the most-testosterone packed creature on earth. Which of these sharks have evolved most efficiently to attack? Which has the sharpest teeth and strongest jaws? Where do they patrol? How do they attack? What is the world’s most dangerous shark?
