Why Are Elephant Ears So Big?

Why are elephant ears so big? Looking for the best explaination? You're at the right place, we round up and give answer for all of random facts throughout the world.

Elephants have big ears to help radiate heat and keep them cool. When elephants flap their wet ears, they cool the blood flowing through the numerous blood vessels in their ears. This helps cool their large bodies.

Most people know that wooly mammoths, who lived in colder areas before they went extinct, looked like hairy elephants. But there’s one major difference: wooly mammoths had much smaller ears. So this tells us that the hot climate elephants live in is responsible for their massive ears.

Elephant ears are one sixth the size of an elephant’s body. That means if you were an elephant, your ears would be the size of your whole head. And they’re important because the bigger you are, the harder it is for you to cool down. Elephants are very big, so living in hot dry climates could be very dangerous for them without some way of cooling off quickly.

That’s where their ears come in. Elephants use their ears like fans to help create breezes, but their ears do more than that. Those big ears are just full of blood vessels. Warm blood from deep within the elephant’s body flows to the ears, where the blood vessels are very close to the skin and lose heat very easily. Elephants will even spray their ears with water to help them lose heat faster. This works so well that blood leaving an elephant’s ear is 9ºC cooler than it was when it entered the ear. An elephant’s ears are its air conditioning!

How can Giraffes live longevity?

How can Giraffes live longevity? We will answer you this animal facts and give some funny images to help you easier when getting the information.

Likelihood of Living to Adulthood

In most cases, giraffes are very social animals. A herd of about 40 giraffes is mostly composed of females and calves with several bulls, or male giraffes mixed in. The young male giraffes move together with the older males and are more solitary and love to live alone.

While in captivity, a giraffe can live for about 28 years or even longer. Many giraffes do not make it into adulthood because more than half of all calves are killed by hyenas, lions, and other predators within the first year after birth.

Protective Features

Giraffes have different features that help them stay safe from predators. For one thing, they are fast, tall, and very strong. This means that it does not have many enemies. The major predators of the giraffe are hyenas, Nile crocodiles, and lions.

With the help of its speed, a baby giraffe is able to get away from such predators. A giraffe can run close to 30 mph and this makes it easier to escape its enemies. However, the giraffe can only keep up with this speed for a short distance. Once it gets tired, a lion can try to knock it down by taking out its long legs.

Another great feature that helps the giraffe survive in the wild is its long neck. The long neck provides the giraffe with a good view of the terrain and therefore it can spot lions and hyenas at a distance. The giraffe is also very powerful. With just one swift kick, it can crush the spine or skull of any attacking lion.

Risk of Endangerment

Although giraffes may seem as though they are at a low risk of becoming endangered, some species are shrinking in number. The Uganda giraffes, for example, are becoming smaller in number. Only 445 giraffes live in the wild. This is because they are hunted for meat and habitat destruction is also becoming a threat.
