Giraffes eat mainly leaves. They are a group of animals known as browsers. They do not live in a specific territory, but browse the savannas looking for food.
Giraffes have the physical adaptation of a long neck (about 6 feet in length) that allow them to reach the leaves at the tops of trees. This allows them to feed when necessary and not have to compete with other animals for the food.
Giraffes eat up to 75 pounds (34 kilograms) of vegetation per day. They spend most of their day eating, because they only get a few leaves per bite. Their favorite tree leaf is the leaves from the acacia tree. The branches of the acacia tree have long thorns, which keep other animals from eating them. However, giraffes have a long tongue, which allows them to reach between the thorns to get the leaves.
