According to National Geographic, a giraffe can reach a height of 19 feet and can weigh as much as 2,800 pounds. Giraffes use their height to reach tall trees and other vegetation where they feed on leaves and buds. The 21-inch tongue of the giraffe assists in reaching difficult spots.
Giraffes spend a significant portion of their time eating and chewing cud. They travel in small groups of about six, foraging for food. Hundreds of pounds of vegetation are required each week. While giraffes derive most of their hydration from the vegetation they eat, their height is a disadvantage for drinking from water holes.
