CHILLING footage of a huge shark prowling the ocean floor has divided opinion as some argue it proves a prehistoric beast still exists.
Megalodons – which grew to 60ft and had a 10ft-wide mouth with 276 teeth – died out some three million years ago.
But footage of a giant shark at the bottom of the Mariana Trench has reignited a debate as some users are convinced it is evidence the colossal creatures still exist.
The clip, that has reemerged from 2018, shows the beast swimming over what appears to be an abandoned shark cage.
One person commented: “Our oceans are huge and there are vast areas that are still unexplored.
“I wouldn’t be surprised if there are megs out there.”
Another said: “I think they went deeper into the seas like the giant squid which is why we never see them.”
But others say the creature is simply a common sleeper shark, which can survive at least 2,000 meters beneath the surface.
It comes after a six-year-old boy found a tooth from a megalodon.
The rare 4in megalodon gnasher is 20 million years old.
Sammy Shelton took it to school and his Beaver Scouts.
He said: “I’m very pleased and will be keeping it safe.”
His family had been walking on Bawdsey beach, Suffolk, just after high tide on May 1.
Dad Peter, 60, of Bradwell, Norfolk, said: “Sammy was hoping to find the odd shark tooth when he spotted this giant one.
“We realized straightaway it was a megalodon’s but didn’t know how rare they were until we talked to other fossil hunters.
“People were getting quite excited.”
Megalodons featured in Jason Statham’s 2018 flick The Meg.
