A drone captured a terrifying moment for a 28 foot boat and it's crew off the shore of Esperance in Western Australia. Dave Riggs was filming a documentary when his drone spotted the enormous great white shark stalking the patrol boat. He estimated the monster shark was about 20 feet long.
The shark was about 150 feet land, and Riggs said it was likely attracted by dead sperm whales that have washed up on the shore. In a Facebook post, Riggs suggested that the dead whales should be towed back out to sea, so the sharks would lured away from the popular beach area.
