The video above, shot by Darren Marshall, was recently posted to AKSinWA’s YouTube channel. According to the video, which was shot in Western Australia, a young humpback whale (Megaptera novaeangliae) died after becoming trapped on a reef.

According to the information in the video, two 8′ tiger sharks (Galeocerdo cuvier) began feeding on the whale within minutes after its death. Within 45 minutes, the number of sharks had risen to approximately 30. The video also notes that bronze whaler sharks (Carcharhinus brachyurus) were also involved in the feeding event.

The sharks fed on the carcass for the next two days, leaving only skeletal remains behind when the feeding event ended.
