If you think you can take on a tiger, consider the fact that they are 20 times stronger than the average human.  In the words of Joe Exotic, tigers are  "A real-life tornado, and there ain’t nothin’ you can do besides protect yourself. "

Snap, crackle, pop. The harmless log that just floated by you has turned into a jaw-snapping death machine. A crocodile may swim by unassumingly but make no mistake, they are on the hunt for their next prey. Crocodiles have heightened smell, sight and hearing, and can hold their breath for over an hour. Their ability to lurk underwater makes them the third most dangerous predator in all of Africa. The freshwater Nile crocodile is one of the deadliest animals on the Nile River, with a wildlife carcass count only behind that of lions and hippos.

In fact, with an average speed of 80 km/h (50 mph) a lion can run almost twice as fast as you can. And if it's gunning for you, a lion can can clock up to 128 km/h (80 mph).

Though they're powerful and fast, black rhinos could not outrun the black market demand for their horns. Nature parks, like the Serengeti Park in Germany, allow endangered species like this to thrive in peace under human supervision. But in 2019, this zookeeper found out that a rhino's temperament can change in an instant, and barely escaped with his life while trapped inside a car. If you were driving through a park, could you outrun a rhino? Are rhinos blind? And how powerful is that horn?

here are three words that put the fear of death into the very bravest of souls.Three words to make your blood run cold. Hungry. Hungry. Hippos. While they make look adorable, hippos are not sweet, gentle creatures. They are the deadliest animal on the Nile River, with their human body count topping that of lions. It's estimated that they kill 500 people per year In Africa. Having said that, I’ve got good news and bad news for you.

You’re enjoying a nice day on an ocean cruise, you're relaxed and  secure.  Too bad that a rogue wave, human error, high winds or mechanical failure  just ruined your trip.
