Giraffes are herbivores, which means that they only eat plants. Their long necks let them reach the tree tops where they browse on the leaves from the trees. Their favorite foods are leaves from mimosa and acacia trees. They eat from other trees and bushes too, but they always choose the leaves they like the most. They pass on grass because they don't like it, and besides it is difficult for them to reach the ground.
Giraffe has a very long, prehensile tongue. Prehensile means that it is made for holding , wrapping around the objects. The tongue is black in colour, and it can be up to 20 inches long. This tongue is like a giraffe's tool for picking up the leaves. Giraffes curl the tongue around the leaves and pick them up. It is interesting that acacia trees have a large, sharp thorns, but the giraffe is able to pick up the leaves and not to get hurt by the thorns. It proves that the tongue is a very good tool.
Giraffes spend most of the day browsing in the trees.They do it for 16 to 20 hours a day. Depending on giraffe's size and appetite he/she can eat 40 to 140 pounds of leaves and plants a day.
Giraffes, like camels, can go for a long time without water, but sometimes they do get thirsty. At times like this they look for a water hole, which is like a pond in savanna where all the animals come to drink or bathe. Once they get there giraffes can drink about 12 gallons of water ot once.
It is difficult for giraffes to drink because they are so tall. To reach the water they have to spread their front legs very wide apart, and they look like they are about to fall.
