Days after two shark attacks were reported along the coast of New South Wales, an Australian diver has captured footage of three great whites and two tiger sharks devouring the carcass of a sperm whale.

The close-quarters footage shows the sharks circling the huge carcass before taking chunks out of it. Watch the footage below to witness nature at its scariest.

If you enjoyed this incredible video of nature at work, then you’ll be glad to hear that Discovery Channel’s annual Shark Week kicked off on Sunday night.

Dubbed the “Super Bowl of the Ocean”, 2015 is the 28th incarnation of the week-long extravaganza.

Take a look below at one of our favourite videos in Shark Week history - although we can understand if North Carolina’s surfing community choose not to after several shark attacks in the past month.
