The clip, filmed in the idyllic Maldives, shows a swimmer innocently drifting in the blue waters while facing the camera.

But out of nowhere, and with shocking speed, the shadowy figure of an enormous shark appears behind the diver.

In a heart-stopping moment, the sneaky shark swiftly opens its jaws before engulfing the diver's head.

For a few seconds, the swimmer's head remains in the mouth of the predator as it shakes the sea explorer around in an attempt to gnaw off their head.

The diver can be seen kicking their feet and spreading their arms, desperately trying to flee the hungry shark.

Miraculously, the swimmer made a lucky escape as the beastly fish unlocked its jaws and swam away, freeing the diver of the chilling attack.

The diver then scrambled away to the surface of the water, waving their hands at the brave cameraman in a warning for them to flee the scene too.
