A drone hovering over the waters of Western Australia caught sight of a literal blood bath.
The drone was operated by Eco Abrolhos Curises to follow two boatloads of tourists on an island cruise. It ended up capturing a feeding frenzy involving about 70 tiger sharks chomping on a dead humpback whale, the AFP reports.
The cruise company posted the video on its Facebook page, showing the pristine blue Australian waters turn a dark crimson.
"Passengers on our 14 day Geraldton to Broome and everywhere in between were treated to an unexpected phenomena whilst cruising inside Dirk Hartog Island. Something to show and tell the Grandchildren," the company wrote in a Facebook post.
Several tourists wrote about their experience viewing the violent scene on the social media site.
"This was truly amazing to witness this act of nature. The drone and GoPro footage far exceeded my videos and pictures. Thank you Jay and crew for taking us here to view this incredible feeding frenzy," Neil Edwards wrote.
Shark Bay, recognized as a World Heritage site, is known for being home to a diverse range of marine life from whales to dolphins to turtles.
