[Wind howling] The Kimberley's labyrinth of caves has become a refuge for many creatures.

They've evolved in isolation for hundreds of thousands of years, which has led to the enormous diversity of species in the region.

There are around 20 known species of geckos alone.

[Hissing] And when you make your home in a cave, it pays to be able to walk on the ceiling.

Geckos have sticky feet and tail pads capable of gripping the rough sandstone, like built-in anti-gravity boots.

Many of these unique geckos have evolved scales with complex colours and textures that blend in perfectly with the rocks in their environment.

But camouflage doesn't have to be boring.

The fringe-toed velvet gecko likes to step out in style.

Its ornamental tail is the perfect accessory to help get away from predators, like this hungry northern quoll.

[Sniffing] The quoll is a skilled hunter.

And this gecko may have to make a sacrifice.

♪ [Chewing] The quoll gets its feed, but our gecko gets to live another day.

And he'll regrow his tail in time.
