Photographer Trevor Frost, has captured stunning (and terrifying) footage of what the inside of a saltwater crocodile's mouth looks like using a series of daring camera deployments.
In an exclusive for the National Geographic, Frost and filmmaker Melissa Lesh have managed to show us what the world looks like from the prey's point of view. Unsurprisingly, it's not a pretty sight.
Obviously, the brave photographer didn't volunteer to be dinner for one evening to capture his footage.
Instead, he deployed remote-controlled toy boats jerry-rigged to hold embedded cameras, the National Geographic said.
The idea was, that once the toy boats were attacked, the camera would do the rest of the work.
"Of course, to get good pictures, you have to get close, and you have to get into their lives," he said.
"Even something as simple as a tripod being up on the boat can be dangerous when you're doing this kind of work.
"I definitely have an enormous respect for the creature, and my heart is always going," he added.
"I'm always thinking about every little thing that could go wrong to make sure that I stay safe and that I keep my team safe as well ... So far I'm still alive, and I've got all my fingers and toes."
