If there's one fact the internet has proved, it's that we are endlessly fascinated by animals and the animal world. Some of them are furry and cute, others fierce and beautiful. But, beyond their captivating looks, their behavior can be surprising.
Many animals live in social groups, such as wolves in a pack. For some species, though, the bonds develop on unique lines. Sea otters, for example, who spend most of their lives floating in the ocean, hold hands as they sleep. It looks touching, but it's also about making sure they don't drift apart during the night. Cows often have a "best friend" -- another cow they bond with for their entire lives.
Talk to the animals
Many species have developed fairly sophisticated systems of communicating with each other. The sounds they make may sound similar to our ears, but in the wild, dolphins actually call out to each other with unique sounds -- calling each other by name, in effect. Humpback whales have been known to sing, but did you know their songs spread from group to group? Horses often use their faces and various expressions to let each other know how they feel. When it comes to buffalo in some parts of the African continent, communication goes as far as being able to vote. A herd will decide which direction to head out in by using a process where the adult females will stand up one by one, looking in the direction they want to go. Then they lay back down. The majority rules.
Despite all our technological advances, the animal world can still stun us with natural ability. The next time you see a spider spinning a web, consider that the delicate silk it uses -- incredibly, thinner than your hair -- is stronger than steel. The poison dart frog of Central and South America has enough deadly venom to kill up to 10 men. The cheetah is the world's fastest land animal, and can outdo the most expensive sports car by accelerating from zero to 60 miles per hour in a mere 3 seconds.
That's just a peek at the many astonishing facts and details about the animal world we live in.
