Giraffes are the tallest mammal in the world! Even baby giraffes are taller than most humans.
Giraffes have a dark purple tongue – it is believed that this dark colour prevents the tongue from getting sunburned while giraffes eat.
Sleep is a tall order
Giraffes sleep only a few hours every day, and generally only for short periods at a time. While they can be seen lying down to sleep, they can also rest or go into a kind of half-sleep while standing up. This is an adaptation for protecting themselves because lying down for long periods in the middle of the plains would leave them extremely vulnerable to predators such as lions or hyenas.
Quick on their feet
Giraffe calves can stand within an hour of being born. This helps the herd to keep moving to avoid predators.
