The Giraffe is the tallest among all living animals. The strange shape has made the giraffe perfectly suitable to obtain its food.
A giraffe eats only the leaves of the plants, so its height enables it to reach the leaves on trees which grow in tropical lands where there is less grass. A giraffe’s tongue is often a foot and half long which it can use skillfully to pick the smallest leaves from the thorny plants without being pricked.
It also has a long upper lip, which helps it to wrench off many leaves at a time. If the giraffe wants to drink water from the ground, it adopts a peculiar style of spreading its legs far apart, so that it can reach down easily.
