My name's Steve Backshall!
Self confessed, shark obsessed.
This is Shark Bites.
There's only one contender for this title.
The most ferocious shark has to go to...
..the mighty Great White -
one of the greatest hunters on our planet.
Reaching lengths of up to six metres, and weighing as much
as a car, Great Whites prey on fish and marine mammals, like seals.
And these colossal carnivores rule their waters.
But what is it that makes them such perfect predators?
Guadalupe Island off the coast of Mexico is the perfect place
to swim with them in the open ocean.
I can't deny I'm a little nervous.
After all, Great Whites are one of the most powerful
creatures on our planet.
So, I think it's time to head out through the open cage door.
VOICEOVER: Out of the blue, and as if from nowhere, a shadow appears.
Look, look at that coming straight towards us!
VOICEOVER: This stealthy approach is just one of the reasons
they are such awesome predators.
With white colourings below, and dark grey markings above,
the Great White has the perfect ocean camouflage,
known as countershading, allowing them to take their prey by surprise.
And it's in this moment of impact that they reveal their second
and most effective predatory tool.
The jaws of the Great White are perhaps what this shark
is best known for - and with good reason.
At any one time, A Great White may have 300 scalpel-sharp
serrated teeth in its mouth, in rows.
The front row is used to capture and devour prey.
The other rows are like spares on a conveyor belt.
When the front row falls out,
the others roll forward to take their place.
This shark may get through 20,000 teeth in a lifetime,
ensuring they never run out of their greatest asset.
Team those serrated teeth with two tonnes of explosive power
and speeds of up to 40km an hour
and this shark is able to drive its prey clear out of the water.
The Great White shark,
the most awesome predatory fish on our planet.
With its cunning camouflage and its terrific teeth,
it is without a doubt the most ferocious fish in our seas.
Steve Backshall meets the most ferocious shark of all. The great white shark is one of the greatest hunters on the planet, and Steve looks at what it is that makes them such perfect predators. He dives with them in the open ocean, revealing clever camouflage, and heads into his shark lab to take a closer look at their terrific teeth.
