Excerpt: Behavioral ecologist Tristan Guttridge has uncovered how orcas, better known as killer whales, have been able to wipe out populations of white sharks around the world - ripping them apart in highly coordinated strikes from the US to Africa.
'These animals are taking out Jaws... surgically removing their liver and leaving the rest of the animal,' Dr Guttridge said during Discovery's annual Shark Week, in a new special airing Tuesday at 9pm ET.
Shockingly, it appears orcas have learned and taught other whales this deadly behavior by practicing on human sailing boats, wrecking and even capsizing hundreds of boats worldwide.
YIKES!
Excerpt: In South Africa, dead white sharks began washing ashore with their livers 'surgically extracted.'
Researchers explained that a shark's liver, which makes up 25 percent of their body weight, represents a pure energy feast to a pod of orcas.
Shark livers help the creature store massive amounts of fuel, and are also filled with oils that help the animal control its ability to float. For a great white shark, the liver can weigh hundreds of pounds.
While the great white is a massive predator, orcas are even bigger and can grow to be over 30 feet long and weigh over 14,000 pounds.
