How the Animal Kingdom Sleeps

Sleep is an unavoidable factor of every day life, and stands as something which has fascinated and confused humans for centuries.

Sleep is a common occurrence for humans, so, have you ever wondered how the rest of the animal kingdom sleep?

Check out these impressive facts below to find out more about sleeping leopards, dozing dolphins and resting elephants…

Dolphins divide their brain

Dolphins are constantly on the move. In order to allow them to keep swimming on, they have the ability to shut down one side of their brain at a time, meaning that the other half is still active!

One side gets around four hours sleep, before a switch occurs – pretty impressive.

Elephants are light sleepers

Elephants are super light sleepers, mainly because they spend the night either moving to a new area, or protecting their family from predators and poachers.

Despite their massive stature and huge brain, elephants have been recorded to sleep only two hours per night!

What’s even more impressive is that their brains lose little to none cognitive ability on low sleep, meaning that elephants function fine on hardly any rest at all.

Sea otters float

Sea otters have several ways of adapting in order to sleep.

Because they sleep on water, they tend to wrap themselves up in kelp and seaweed to stay protected and hidden from below.

Another novel way in which they stay safe is to clasp hands with fellow otters, so that they do not float away in the night!

Giraffes adapt

When it comes to sleep, giraffes have a tricky body size and shape to deal with.

They get around the obstacle of their stature by curling up, much like a cat or dog, and letting their head rest on their rear end!

Sounds pretty comfy to me.

Sloths aren’t that lazy

Although the stereotype of the sloth is that they sleep for hours and hours on end, this is mainly based off our studies on them in captivity.

Wild sloths sleep for around ten hours per day, not that much more than your average college student!

Walruses use an anchor

Walruses have to adapt when it comes to sleeping, especially when it comes to sleeping in the sea with the waves crashing around them.

They tend to opt for a special technique of plunging their tusks into ice for an anchor, before having a snooze.

It’s a super effective way of keeping them in place!

Horses lock their legs

Horses can actually lock their legs into position before they rest, meaning that they can sleep whilst standing up!

They’re also super light sleepers too, and with their standing position, their sleeping method allows them to run from predators if needed.
