This amazing video shows the moment an unsuspecting crab is grabbed in the tentacles of an octopus that shoots from the water to snatch it.
The footage was shot by Porsche Indrise in Western Australia and uploaded onto YouTube. "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," she said.
The video has had almost four million views in less than a week.
