This Is How Giraffes Sleep
Take a good look at these giraffe nap pics, because you won’t often catch a giraffe sleeping. Until the 1950s, researchers believed that giraffes don’t sleep at all.
In fact, despite being the tallest animal, giraffes have the shortest sleep requirements of any mammal, sleeping an average of just 30 minutes per day. And when they do sleep, usually it’s just for a few minutes.
