A film crew is capturing footage for a documentary about animal conservation on a remote peninsula in Russia when they're approached by a polar bear. The crew begins to try to scare off the bear by making loud, aggressive noises — which, amazingly, works. Filming wildlife definitely has its drawbacks, especially when a giant bear gets a little too close for their close-up.
Speaking of filming wildlife, these divers are also getting too close for comfort. They're swimming with a massive anaconda while down in this Brazilian river and it looks...intimidating. The footage is awesome, but we'll leave the whole swimming-with-enormous-snakes thing to these guys.
