@10newsau: Drone footage has captured the moment a shark begins to feast on a whale that died after becoming stranded off the coast of Perth. The huge sperm whale was spotted over the weekend after it become stuck on a sand bank at a Perth beach, before it swam back out to sea and tragically passed away. The whale carcass is being monitored by authorities before it will be taken out of the water and buried. #whale #whales #shark #ocean #drone #dronevideo #perth #westernaustralia
