Chilling video shows the moment a cheetah makes the fatal error of drinking from a watering hole and is snatched by a crocodile lurking just beneath the surface.

The mammal was no match for the hulking reptile, and was clearly not wary enough as it approached the water to take a drink.

Suspense builds as the cub appears to notice the croc, growling and baring its teeth at the water as it tentatively approaches the water and dips down.

The cat’s mother and her other cub can be seen in the background at a more cautious distance from the shoreline, leaving it alone and more vulnerable to attack.

As the cheetah bravely inches closer to the water to get a much-needed drink, the crocodile expertly springs out and snaps its jaws around the cub’s neck, with the animal leaping into the air and clawing at the beast in vain as it tries to escape.

The cheetah had very little chance of survival as the killer croc rapidly drags it down deep into the water and drowns it. Tragically, the cheetah’s mother and sibling can be heard calling out in despair for the lost cub.

The incredible footage, shot from a game vehicle at the &Beyond Phinda nature reserve in South Africa, reveals the cheetah’s terrifying final moments…
