Giraffes spend most of their day eating because they get just a few leaves in each bite. Their favorite leaves are from the acacia tree. Acacia trees have long thorns that keep most animals from eating the leaves. But those thorns don't stop the giraffes! They simply use their 18-inch (46-centimeter) tongues to reach around the thorns. It is thought that the dark color of their tongues protect them from getting sunburned while reaching for leaves on trees. The zoo website: http://sandiegozoo.org/
