Giraffes have long, prehensile tongues that can reach up to 2 feet (60 centimeters) in length. This allows them to access leaves and buds from high branches that other animals cannot reach. Their tongues are also covered in papillae, small bumps that help them grip and manipulate the foliage.
Giraffes have a four-chambered stomach, similar to cows and other ruminant animals. This allows them to effectively digest the tough plant material they consume. They regurgitate and re-chew their food, which helps break down the cellulose and extract the maximum nutrients.
Giraffes are known to be selective feeders and will often choose the most nutritious plants available. They may travel long distances in search of the best grazing areas. Their long necks and tall stature give them an advantage in reaching the higher leaves and buds that other animals cannot reach.
In summary, giraffes can consume a significant amount of food, up to 75 pounds per day, consisting primarily of leaves, shoots, and buds. Their long tongues, specialized teeth, and four-chambered stomach help them efficiently acquire and digest their plant-based diet.
