Just as important to survival as food and water, sleep plays a critical role in the health and wellbeing of almost every animal.
Sleeping patterns may vary wildly throughout the animal kingdom, but at the end of the day all creatures – no matter how big or small – share the need for sleep. Over the years, animal experts have conducted countless studies looking into the subject of animal sleep and have found many unique and fascinating sleeping patterns.
Many members of the natural world have evolved to be incredibly light-sleepers for survival reasons. For example, did you know that dolphins and whales can only rest one-half of their brain at a time? In this state of “sleep-swim”, they can never enter a deep sleep. Another impressively light-sleeper is the giraffe which can go for weeks without sleep and they doze off for longer than 5 minutes at a time.
On the flip side, there is also a wide range of animals that enjoy long periods of sleep. For example, the Little Brown Bat is famous for its unusual sleeping position (it hangs upside-down) and typically snoozes for an astonishing 19.9 hours every day.
