Giant Otter Deadly 60 Bites

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

Here's just one of my many favourites.

This is Deadly 60 Bites!

'We've just struck gold in the heart of the Amazon rainforest

'and come across a pack of extremely rare giant otters.'

Look at that! Wow!

The water's just parting in front of him. He's coming right up to us!

You can see the power of them as they swim.

'Make no mistake. These are otters with attitude.

'At two metres, they're as long as I am tall. A formidable force.'

Local people call these animals river wolves,

and it's a really apt name.

Firstly you look in their mouths,

and they've got canine teeth that wouldn't look out of place

on a wolf.

Secondly, they're the longest of the weasel family,

and in weight - about 35 kilos -

actually not that dissimilar to a wolf.

And thirdly, they hunt in packs.

This group moving along this riverbank

are moving in unison, frightening and disorientating the fish

and catching them down there in the dark,

using their tactile whiskers to feel them.

Giant otters are perfectly evolved for hunting in the murky waters

of the Amazon basin.

Their broad, wing-like tail is the perfect engine,

allowing them to fly through the water,

with webbed feet for fine control.

And their eyesight is pin-sharp,

but fishing blind is no problem. These awesome anglers

use their whiskers to follow the wake of a fish long after it's gone,

meaning prey can swim but it can't hide.

By working together, a group of giant otters confuse their prey,

giving it almost no chance.

They're a deadly team both above and below the water.

OTTER WHISTLES

One, two, three heads come to the surface. Five heads to the surface.

Three of them have got fish.

That is incredible.

You'd be hard-pressed to find any other predator in the world

that has that kind of success ratio when they're hunting.

OTTER GRUNTS AND CRUNCHES

I've seen lions hunting, orca, great white,

but none of them come even close to being as efficient as these guys.

And that's why they're going on the Deadly 60.

How good was that?!
