If you needed any more proof that nature is ruthless, scary and unforgiving, take a peek at this video of giant spider crabs ripping a poor octopus to shreds.
Spider crabs usually migrate to Port Phillip Bay, Australia from May to July as waters cool down, so seeing this kind of migration in February is surprising. Chiharu Shimowada, the diver who provided this video to Storyful, said in his 10 years of scuba he has never seen anything like this.
At least we know they're eating well on the way to their new home. Yikes.
