Although giraffes have extremely long necks, they only have seven cervical vertebrae, which is the same number found in humans. These vertebrae are elongated, giving the giraffe its extreme height. Each vertebrae may be over 10 inches long.Know More
Each vertebrae is connected by a ball-and-socket joint, giving the giraffe greater range of motion in the neck. This is the same type of joint that humans have in their shoulders. Giraffes average between 14 and 17 feet tall, with the neck providing approximately six feet of that height. The neck alone weighs about 600 pounds.
A long neck allows the giraffes to feed on trees that other animals cannot reach, including acacia trees, a favorite food for giraffes. Long tongues, averaging 18 inches, allow the giraffe to reach even higher for foliage. Giraffes eat up to 75 pounds of foliage and drink as much as 100 gallons of water each day.
Giraffes also use their long necks to establish dominance using a behavior called necking. Usually seen in males, necking occurs when a giraffe swings his neck to head-butt an opponent.
Its long neck gives the giraffe the necessary height to look for encroaching predators, such as lions and crocodiles. Giraffes can run approximately 35 miles per hour to escape predators and use their legs to deliver powerful kicks.Learn more about Giraffes
Adult giraffes are typically between 14 and 19 feet tall. Calves, or young giraffes, are an average of 6 feet tall when they're born. Giraffes are the tallest land animals in the world.Full Answer >
Jean Baptiste Lamarck, a French biologist who had an alternate evolutionary theory of biology to that of Charles Darwin, explained that giraffes have long necks because as they reached for leaves in high branches of trees, their necks became longer and stronger. Their offspring, in turn, would inherit necks that were slightly longer.Full Answer >
Giraffes have adapted to their environment over the years by growing long necks to reach the vegetation found in tall trees where they live. Giraffes have also adapted to their environment by being able to drink 12 gallons of water at one time so that they do not have to worry about finding water holes as often as other animals living in the African wilderness.Full Answer >
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.Full Answer >
