Why are giraffes the tallest animal on earth?

Giraffes are the world’s tallest mammals, thanks to their towering legs and long necks. A giraffe’s legs alone are taller than many humans—about 6 feet .

Why do giraffes have such long?

It appears obvious: the giraffe’s neck, which can grow to as much as two metres in length, has been selected because it gives its owner exclusive access to the topmost leaves of the trees, and no other animal can reach them.

What is the advantage of a giraffe height?

Diet: Giraffes are herbivores, feasting on hundreds of pounds of leaves a week and traveling miles in search of food. Their height gives them an advantage over other African herbivores, as they can reach the high branches for young leaves. Their 18-inch tongue helps them reach some of the tougher leaves.

Many observers of giraffes have noted their extraordinarily long necks, leading to a great deal of speculation about why giraffes have long necks.

Why do giraffes have a thick tongue?

Fortunately, a giraffe’s tongue has thickened papillae , which helps to protect it from these vicious thorns.
