Great white sharks facing obesity crisis because they keep feasting on whales

Great white sharks might need to watch their waistlines after experts reported the seafaring creatures were teaming up to take down massive whales.

Doing so means there's plenty of food to go around among the dangerous predators, but experts think it's a worrying development as sharks begin teaming with one another rather than fighting for food.

After years of campaigning to protect endangered shark species and their food sources, the great white sharks are getting even bigger and finding it much easier to feed themselves.

More resources and food for a number of shark species, especially tiger sharks and great whites means experts are finding bigger and bigger sharks.

While tiger sharks usually measure up to 12ft, marine biologist Kori Burkhardt discovered a 16ft tiger shark in the waters of French Polynesia.

Kori said: "When we first met Kamakai it was really unexpected. I’ve been diving with tiger sharks in multiple countries and she’s by far the biggest I’ve ever seen.

"It’s not just her length but her width as well. She can be five metres long but she’s three metres (9ft) wide, including her fins. That’s insane."

The shark dubbed Kamakai, which was first spotted three years ago, isn't the only plus-sized shark on the prowl.

During filming of upcoming Nat Geo WILD documentary Great White V Tiger Shark, documentarians are said to have discovered "two of the largest white sharks ever recorded in Hawaii".

While most great white sharks can grow up to a whopping 16ft, the sharks encountered by the crew are said to have measured up to a terrifying 20ft long.

Dr Chris Lowe, upon finding three 20ft great white sharks feasting on a whale carcass, said: "Finding one white shark and a whale, sure. Getting three large female white sharks on a whale, that’s different.

"That means those sharks must have been close enough in the vicinity to detect the odour of that whale, and then also it might mean that these sharks are travelling together. It’s something we’ve never really been able to study or understand."
