OCTOPUS launches a surprise attack from a rock pool on an unsuspecting crab

Believed to be filmed in Yallingup, a town southwest of Western Australia, a beachgoer is quite aptly shocked by what she has witnessed.

The footage begins as the crab edges closer to a rockpool, seemingly testing the waters.  

But much to its unforeseen misfortune, a swift moving octopus launches at the crab and drags it back into the water. 

The woman filming the scene, believed to be Porsche Indrisie, certainly got more than she bargained for when she decided to film the crab. 

'There's an octopus eating a crab!' she yells as the tentacled sea creature shoots out of the water and tries to swallow the crustacean whole.

'I didn't know why I chose to film this crab, but thought I would try and get closer to it but something else beat me to it,' Ms Indrisie later wrote under her video which she uploaded on YouTube.

'The best and unexpected video I've ever captured!'

She also placed the footage on Facebook on Thursday which has since gained 173,682 views and 4,145 shares.

Ms Indrisie was evidently left stunned by what she had just observed, simply saying at the end of her 49 second video: 'Holy s**t!'.

There really is no better way to put it.
