So, the jury is still out on the why behind sleep. What we do know is that essentially all animals rest — though detailed studies have mostly taken place in mammals and birds.
Style of sleep varies greatly across the animal kingdom. Basic survival has likely driven different animals to develop their unique sleep habits, says Tom Stalf, president and CEO of the Columbus Zoo and Aquarium. The tallest animal on earth, giraffes, have often been touted as the mammal that sleeps least of all, despite weighing up to 3, pounds. One commonly cited statistic estimates they sleep only 30 minutes per day.
Part of the difficulty monitoring giraffe sleep stems from their exceptionally strange sleeping pattern. They take a series of short power naps, just several minutes at a time, throughout the day. This often happens while standing — likely an adaptation to protect themselves from predators, since the long-legged giraffe is slow to transition from laying down to standing. The elephant is another contender for the least sleep in a mammal. So while these sleeping animals might not seem very impressive, you're witnessing something few people have ever seen!
