Fun facts about the Giraffe
A giraffe's tongue is 45–50 cm long and dark blue-black, thought to protect it from sunburn during long hours of feeding. Despite their towering necks, giraffes have exactly the same number of cervical vertebrae as humans — just seven. Newborn giraffes drop nearly two metres to the ground at birth and are walking within hours. Giraffes only sleep around 30 minutes a day, usually in short naps of a few minutes.
