sometimes, senses that we don'’’t even have, like the platypus'’’ electro sense.

Sometimes, senses that we do have but that are just much stronger in an animal because of special organs or features.

(Gasping) Like the pit vipers.

This eastern diamondback rattlesnake has special powerful heat sensors that can detect its prey by actually seeing the prey'’’s body heat MARTIN: See those tiny little holes above the rattlesnake'’’s lip?

Those are the pit organs.

The heat sensors.

They give the rattlesnake it'’’s heat-sensing power.

And that comes in really handy when you'’’re trying to find warm-bodied prey like rodents and small birds.

Right, Martin?

Martin?

Where'’’d he go?

Martin?

Shh!

I'’’m hiding from Chris.

He'’’s never going to find me.

CHRIS: Martin?

Hm, where'’’d he go?

I'’’ll track him using the heat-sensing power of the rattlesnake.

With these goggles, I can actually see heat, rattlesnake-style.

Anything warm will glow red, sensing heat a lot like a rattlesnake'’’s pit organs do.

(Gasping) There'’’s something warm.

It'’’s a bobwhite!

Bobwhites, mice and chipmunks are all tasty meals for a hunting rattlesnake.

Be careful, buddy.

Oh, there'’’s a spot!

Hm, where is he?

Where are all the warm bodies?

(Gasping) Oh, there.

There'’’s something hiding behind that stump.

When the rattlesnake gets close enough, he strikes!

(Screaming) I got you.

Oh!

How'’’d you find me?

With rattlesnake sensory power.

My turn with the goggles.

You got it!

All right.

We'’’ll see you on the creature trail.
