Wizz nature

Bulls run faster uphill than downhill.
This is mainly because they have longer hind legs than front legs. Their legs are also very powerful and can run at speeds of 35 mph.

An extinct species of penguins was nearly 7-feet tall!
The biggest penguins around nowadays are emperor penguins, measuring a respectable 4 feet in height.

However, 37 million years ago, a species known as Palaeeudyptes klekowskii, or colossus penguins, roamed Antarctica. They weighed about 250 pounds and stood about 6 feet, 6 inches tall, which is the height of the average NBA player. Unfortunately, like modern penguins, these colossus penguins could neither fly nor, presumably, dunk. But it's still fun to imagine a penguin going one-on-one with LeBron James.

Turns out, Jaws really blew things out of proportion for sharks. According to the Center for Disease Control, sharks kill an average of four people per year, while cows kill an average of 22 annually. Though some are due to road accidents, 75 percent were premeditated attacks.

"What's really chilling is that, in five cases, people were killed by multiple cows in group attacks," one Gizmodo reporter wrote. "Group attacks can be surprisingly well-coordinated. When they're feeling defensive, cows will gather in a circle, all facing outwards, lowering their heads and stamping the ground. When they're feeling offensive, certain cows lead the charge."
