A shark has been filmed repeatedly swimming up to a diving cage and 'biting' at it, baring its massive teeth at the divers inside.

The footage was shared on the Calypso Star Charters Facebook page, where the company said it had been filmed during a dive on 7 October by a customer called Nicholas Jones.
The group's cage had been in the waters at Neptune Island Marine Park off Port Lincoln in South Australia.
The post said: "Such happy and curious sharks throughout the day!"
The impressive - if not hugely daunting - clip soon racked up more than 1,000 reactions on Facebook, along with hundreds of comments from impressed social media users.

One person wrote: "I'm super jealous that's awesome. Up close and biting the cage. Wish on my trip the shark did that."
Someone else said: "Seriously, that would be a bucket list dream come true!"
In the comments section, Calypso Star Charters also explained that the movements the 'curious' shark made were an example of 'mouthing', where the beast uses its mouth to feel its surroundings - y'know, given that it doesn't have hands or anything.

The company also said they had recently been experiencing particularly high levels of sightings, which is good news for any adrenaline junkies hoping to recreate the moment.
One person who's not afraid of the big bad shark is eight-year-old Jayden Millauro, who is believed to have broken world records after reeling in a giant shark eight times his own weight.
Jayden - who is the youngest member of the Port Hacking Game Fishing Club in New South Wales, Australia - was out fishing off the coast of Browns Mountain, 160km south of Sydney.
He recently managed to pull in a massive 314kg tiger shark, despite only weighing 40kg himself.

Jayden told The Daily Telegraph he was understandably 'nervous' as the shark was dragged onto the boat.
He said: "I was thinking that I hope the crew can (get) the shark (on the boat) because I don't want to lose it.
"I was really excited when they got it."
But incredibly he was able to overcome his nerves and eventually pulled the huge creature onto the boat using a 15kg fishing line.

Jayden's impressive haul is yet to be officially confirmed as a new world record.
According to Nine News, the current world record for catching the biggest shark is held by Ian Hissey, who landed a 312kg tiger shark in April 1997.
He has apparently held the International Game Fish Association's 'small fry' record for 22 years.
