A 2,000-pound animal may not immediately cause someone to think it'll be fast, but don't let that fool you. A tour group in Yellowstone Park saw that the bigger they are, the fast they run — in this bisons case, at least. We're not sure if the bison was running away from or toward something, but ...

After noticing a group of grizzly bears on his families property, a father tried to scare them off by firing a warning shot with a shotgun. It turns out it wasn't the best idea as it only provoked the bear into charging at him. Fortunately, he was able to get another shot off in time to stun the ...

A group visiting a beach in New Zealand had an experience they won't forget after spotting an orca swimming nearby. Not long after spotting it, the whale starts to swim right towards them, prompting them all to turn around and sprint for the shore. It's more than likely the orca was just ...

This shows just how fast an encounter with a grizzly can turn into an incredibly dangerous situation. Casey Anderson, a filmmaker, was out recording when a momma grizzly with a cub decided he had gotten too close. She starts sprinting toward him as he gets his can of bear spray ready — the fence ...

It's never going to go well when a mama bear spots someone near her cubs. Caleb Invidiata was on a hunt with Shannon long when they thought they were in a great spot to enjoy watching a bear family go after some bait they had set out during a bear hunt. When the momma bear did notice the ...

A run-in with a nearby moose almost ended very badly for a man and a woman. With an angry moose looking like it was going to charge at any second, the man grabbed the only thing he had — an iron bar. It's not exactly the best defense to stop an animal that's ten times your weight, but he's able ...

A day on a river-safari nearly turned into a deadly situation when an elephant took issue with the boat getting too close. "We were driving on the river, looking out for wildlife, when we came across a bunch of boats circling around an elephant wading in the river," said Su-an Marais, a radio ...

We hope these park workers have some good insurance because working that close to a real-life dinosaur without a cage or fence might shorten their lifespan! Park workers at this Australian reptile park found out really quick that this massive saltwater crocodile isn't a fan of push mowers while ...

It's a good thing these hunters were quick on the trigger pull, otherwise, this angry boar could've caused a lot of damage. Luckily for them, they were able to drop the boar right away and saved themselves from a serious goring.

It'd be easy to take one look at a hippopotamus and assume it couldn't get in much of a hurry even if it wanted to. Let's just hope you've never put that assumption to the test because it's dead wrong. Look no further than this incredible highspeed charge as a hippo erupts out of the water like ...

Just in case you needed convincing that it's in your best interest to not make a rhino mad, then look no further. It doesn't matter if it's an animal, a car or a bus; a ticked off rhino will charge and tackle anything that's in its way.

It sounds unlikely, but all it took for this guy to stop a ticked off ram from charging was pick up a stick. We're not exactly sure what it is about the stick that makes it stop in its tracks and back up, but it happens every time it runs at the guy. The ram eventually decides to give up — but ...

Common sense wasn't present among these visitors who got too close to a bison at Yellowstone National Park. From the start, it's clear this can only go one way — bad. The tourists find out soon enough why you aren't supposed to approach a wild bison when it gets fed up and decides to charge. ...

This baby bunny may be small, but it has a lot of fight! After being picked up by a guy, it started screaming as its mother can be seen hopping off under the truck. Clearly this guy didn't think he'd be met with so much resistance, so he sat it back down. But the bunny wasn't going to let things ...
