Humans may need at least 7 to 9 hours of sleep a night, but many animals are quite different when it comes to their sleep habits. Although they may not have found a Beautyrest like some of us, these animals have amazingly adapted to get the rest they need.

1. Sea otters hold hands while sleeping.

Sea otters float in groups while they eat, rest and sleep to avoid drifting away. Otters will also wrap themselves in seaweed and other sea plants to stay in place. How cute is that?

2. Giraffes can go weeks without napping.

Giraffes are large and relatively slow animals that are prone to attacks from predators and can’t sleep for extended periods of time.

3. Cats sleep 13 to 14 hours a day on average.

Domestic cats and big cats like lions both roam at night and do not need to be alert constantly to protect themselves.

4. Dolphins and whales snooze with half of their brain.

Both can sleep with brain waves of non-REM sleep functioning in one hemisphere while the other half remains awake.

5. Little brown bats sleep about 19 hours a day.

These nocturnal creatures also sleep upside down, allowing them an easy takeoff with their weak wings.

6. Albatrosses can sleep while flying.

Really! This sea bird spends much of its time on the hunt. Since its lifestyle doesn’t allow for time to sleep, it is believed the albatross multitasks and takes power naps during flight.

7. Elephants, zebras and horses sleep standing up.

These animals can lock their legs in a straight standing position called a “stay apparatus.”

8. Frogs hibernate in winter and spring back to life after being frozen.

Much like bears, frogs hibernate during winter. They “wake up” when spring arrives and “antifreeze,” or high concentrations of glucose, prevents the frog’s organs from freezing.

9. Meerkats sleep in packs.

Meerkats cuddle up in heaps, getting warmth from one another and protecting the group leaders at the bottom of the pile.
