These two playful gorillas picked the wrong primate to play around during their shenanigans at the San Diego Zoo. After rolling around on the ground inside a glass enclosure while visitors observed, it appears a nearby silverback gorilla isn't paying them much attention as the two gorillas ...

Don't tick this hornworm off or you might get flung through the air. At least, if you're a beetle, otherwise it'll just strike with its tail a lot.

These hyenas find out that age is just a number when they steal a kill from an old male lion. Despite their numbers, the lion doesn't hold back as he charges in and scares them off, where he proceeds to roar in what we can only imagine is the equivalent of him yelling, "get off my lawn!"

Don't show up outside this lions door if you're hoping for a warm welcome. Visitors who spot this lion at the Capitol of Texas Zoo can expect to find a lion that's more "get off my lawn!" than king of the jungle.

It doesn't get much more passive-aggressive than this ticked off lion who decides to scare off these tourists in an unexpected way. After making a bunch of noise and forcing the lion to come out, he slowly walks up. Instead of leaping toward them or roaring, the lion turns around and pees right ...

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 ...

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 ...

Whether you're hunting predator or prey, it can be dangerous to approach them after they're shot if you aren't completely sure they're dead. These hunters make the mistake of going in for the photo op a little too early after shooting a wolf. It doesn't take long for them to realize it may not ...

A good rule to go by in life is to avoid any animal that has figured out how to wield a knife. This guy clearly never got the memo as he faces down a crab wielding a blue handled knife on the sidewalk. We're not sure where the crab got the knife or where it learned to use it, but we're pretty ...

Two heads may not always be better than one. At least, that's the case for these two cheetahs when confronted with an angry bat-eared fox. They clearly thought this little guy would be easy prey judging by their confused behavior. But he isn't about to be anyone's lunch!

It's a question people never want to have to find out the answer to firsthand — what would you do if a grizzly bear was charging you? Unfortunately, if you're ever in the outdoors in grizzly country, it's a question you just might find the answer to at some point in your life. Steven Rinella ...

Pufferfish aren't really known for being vicious fish. Besides being incredibly poisonous if ingested without proper preparation, they're relatively harmless, right? Maybe not! This shrimp finds out the hard way what happens when you mess with a pufferfish and can't finish the job. One little ...

We wouldn't recommend getting in the cage with a seemingly well-mannered lion, much less what this guy does. In what is either the bravest or dumbest thing we could imagine doing with a lion, he sits down beside her and starts petting her. She's not exactly happy about it either as she starts ...
