Shocking footage has been shared showing the moment two of the world's deadliest predators came face to face. Watch the face-off in the clip below:
In the pretty terrifying footage, a crocodile can be seen being stalked by a tiger shark in the shallow waters off the coast of Australia.
The clip, which was filmed on a drone, shows the shark trailing the croc for around two minutes.
Clearly not the croc's first rodeo, it can feel something on its tail, so makes a move for the rocks further ahead, escaping the shark's jaws.
Duncan, who was controlling the drone, said he was around 10 metres away from the pair when he noticed the pursuit through the clear water.
Speaking about the encounter, he said the croc appeared to be a 'bit weary' of the shark and was very 'keen' to get onto the rocks. Well, you would be, wouldn't you?
He said: "The shark did get really close to the croc so I thought something might happen, but it probably had second thoughts."
Chillingly, because of the reflection from the sea and bright sun, anyone swimming on the surface nearby wouldn't have been aware that the deadly duo were so close.
But this isn't the first time the species have come face to face. Oh, no.
Drone footage shared last year shows a massive crocodile and bull shark swimming up to each other in a river in Australia - in an area where 'locals are always in the water'.
The video was filmed near Ivanhoe Crossing in Kununurra, Western Australia, a picturesque tourist attraction on the lower Ord River.
Caravanners Chelsea Wood and Bryce Connole had been fishing and set up their drone to see what was lurking in the water.
They were shocked to spot not just a large bull shark just metres away from them, but also a gigantic salt water crocodile.
In the clip, the shark can be seen swimming up to the crocodile before quickly changing direction - supposedly having clocked just how much it's dwarfed by its would-be opponent.
The crocodile, meanwhile, floats calmly, presumably awaiting its next meal patiently.
It then casually swims off in another direction, as if this had been the plan all along. I'm sure avoiding the giant croc in front of it was merely coincidental...
Speaking to the Daily Mail, Chelsea said the area is a popular swimming spot for locals.
"We didn't realise crocodiles or sharks were in the area as locals are always in the water," she said, adding that there were children in the water nearby at the time.
"I think this was a rare sighting but probably good for people to see what's lurking around the waters in the Kimberley Region."
