CHILLING footage of a huge shark prowling the ocean floor has divided opinion as some say it proves a prehistoric beast still exists.
Megalodons – which grew to 60ft and had a 10ft wide mouth with 276 teeth – went extinct around three million years ago.
But images of a giant shark at the bottom of the Mariana Trench have reignited debate as some users believe it’s proof the colossal creatures still exist.
The clip, which resurfaced in 2018, shows the beast swimming above what appears to be an abandoned shark cage.
One person commented: “Our oceans are huge and there are vast areas still unexplored.
“I wouldn’t be surprised if there were mega releases there.”
Another said: ‘I think they got deeper into the seas like the giant squid that’s why we never see them.’
But others say the creature is simply a common sleeper shark, which can survive at least 2,000 meters below the surface.
It comes after a six-year-old boy found a tooth from a megalodon.
The rare 4-inch megalodon gnasher is 20 million years old.
Sammy Shelton brought it to school and his Beaver Scouts.
He said: “I’m very happy and will keep it safe.”
His family were strolling on the beach at Bawdsey, Suffolk, just after high tide on May Day.
Dad Peter, 60, from Bradwell, Norfolk, said: “Sammy was hoping to find the odd shark tooth when he spotted this giant.
“We immediately realized it was a megalodon, but we didn’t know how rare they were until we talked to other fossil hunters.
“People were getting pretty excited.”
Megalodons featured in Jason Statham’s 2018 film The Meg.
