Barracuda Deadly 60 Bites

On Deadly 60, I've had loads of incredible animal encounters.

Shark! 'Here's one of my many favourites.'

Today, we're in Borneo,

hanging out with the Bajau sea gypsies, who live on this island and in the sea around the reef.

The world beneath their boats is a multi-coloured dream

of dazzling marine creatures. But for the moment,

the most fascinating thing to them is our cameras.

We've had a tip-off. There's one place around here

that attracts the largest, most powerful predators,

so that's exactly where we're diving now, to find my next deadly animal.

It's not far from the reef. In fact, it's the edge of it.

The reef really feels like home...

..when just at the end of it you've got this.

The drop off.

This is where the reef meets the open ocean.

The drop off disappears 600 metres straight down into the abyss.

It gives you vertigo.

It's like stepping off the edge of a cliff

with the big blue beneath you.

There are still plenty of fish here, but they daren't stray too far

from the wall, because the open ocean is full of lethal killers.

They're keeping close to the coral,

cos it keeps them safe from the big fish with the big teeth.

And then looming out of the deep blue,

one of the fastest assassins in the sea.

Steve, check out the fish up above you.

Dogtooth tuna - with power, speed and sharp teeth, this is the real deal.

It's swimming straight at our cameraman -

look at that! Gulping, his mouth open.

Wonderful stuff!

I love it!

Fierce hunters stalk the depths, just waiting

for a small fish to stray too far from home.

This is another one of the speed merchants of the sea.

It's a giant trevally.

There's another one over there as well.

Look at the size of them!

Absolutely huge.

They're exceptional hunters.

At the moment, they're just curling along the outside...

..looking for something to snap up. No way I'm keeping up with them.

Cruising through crystal seas, the sun cuts down through the blue.

Then suddenly, it seemed a huge cloud blocked out the sun.

But it wasn't a cloud.

It was one of the world's most awe-inspiring wildlife spectacles.

That is the largest school of barracuda I've ever seen.

This is absolutely dazzling.

One of the meanest...

fastest, fiercest fish in the sea.

And I've never seen so many of them.

Ha-ha-ha!

That is unbelievable!

Absolutely surrounded by them.

I've never seen anything like it!

They're almost surrounding me in a circle.

Spinning around and around.

This is absolutely dazzling.

Barracuda are all about teeth.

They have two sets - the huge long teeth at the front are used to grab their prey,

but the real damage is done by the teeth at the back.

They act like scissors, cutting prey in half in a single bite.

Even sharks can't do that.

When you're diving with barracuda, it's wise to keep your hands

tucked in and don't show off silvery items like watches,

otherwise they might mistake it for a small fish

and then you're going to lose your hand.

Look at them! There are thousands of them!

I've never seen anything like it!

Although they look totally effortless in the way they move,

actually they're really travelling quite fast.

I'm breathing pretty heavily just keeping up with them.

Barracuda -

definitely going on my Deadly 60.

Hanging around in whirlwind shoals,

lightning fast with terrifying teeth,

barracuda are the wolves of the sea.

and definitely worthy of a spot on my Deadly 60.
