15 Animals With Interesting Sleeping Habits

Everyone needs a good night’s rest, or at the very least, a decent power nap on occasion. These 15 animals have taken sleep to fascinating and sometimes extreme places.


The internet is full of animals in the wild doing adorable things (Those foxes are hugging! That ostrich is dancing!); it’s understandable if one were to forget for a moment that nature itself can be a harsh beast. That is why creatures of all shapes and sizes have developed sleep routines that are based not around comfort, but purely on survival of the fittest.

Some people equate sleep with wasted time. Donald Trump claims to only get three hours of sleep a night, saying that it helps him stay ahead of the competition. However, any competition we experience in the human world pales when compared to what is seen in the world of animals.
Giraffes manage to function on only 20-30 minutes of sleep daily. Having to worry about lions, hyenas and leopards all wanting to snack on you can make any long nap the last one a giraffe might take. Albatrosses, despite having a claim to fame for their Monty Python connection (Albatross! Albatross!) essentially live their life in the air, relying on the wonders of something called dynamic soaring that allows them to ride wind currents for days at a time and catch some mid-flight shuteye while they’re at it.

Then there’s toads and frogs—slightly slimy critters that often spend their winters, for all intents and purposes, dead. Although different species of these amphibians have their own hibernation regimen, land-based frogs freeze—literally—during the winter months. Glucose acts as a life-giving fuel that keeps a dormant frog alive while its major internal organs, like the heart and lungs, take a break. Wouldn’t it just be easier to head to Florida when the cold weather hits?
Let’s take a look at fascinating sleep habits of the animal kingdom in more detail:

As we’ve mentioned already, giraffe’s can function on only 20-30 minutes of sleep per day—but it gets even more interesting. They get to that total by taking naps that rarely last more than five minutes at a time. What an amazing way to get your rest while never getting far from the herd.

Sure, there is an ever-present fear of death, and if they sleep too long they run the risk of being attacked by lions or other predators, but think of how much they can get done in a day!

Meerkat

Meerkats easily win the cuddling championship of the animal kingdom. They gather in groups of up to 40 and dig communal holes for their sleeping chambers.

Once inside the hole, the meerkats huddle together in a pile to stay warm—protecting their leaders at the bottom of the pile.
You have to be friendly to have that kind of closeness. Let’s just hope that none of them snore.

Bears

Bears are renowned in the animal world for their hibernation abilities, but what does hibernation really mean? Well, it isn’t as simple as Disney portrays it. When bears hibernate, they do so to avoid starvation during winter months when there is little or no available food. The exact mechanism of hibernation is pretty complex. The heart rate, respiration, and metabolism all drop to help conserve energy.

During the hibernation process, bears live off of body fat they stored prior to hibernation season beginning. While hibernating, a bear can lose up to a quarter of it’s body weight.
Some bears can sleep for up to 100 days without eating or releasing waste. They have an incredibly evolved system that recycles their bodily waste and even keeps their muscles from atrophying. I guess that solves any late-night trips to the bathroom!

Frogs

Frogs can be a bit of a mystery sometimes. Where do they go during the winter? Well, it turns out that they can sleep through the winter as well—but they do it in a very different way than bears do. During a frog’s hibernation, their heart stops beating entirely and they stop breathing.

While that’s what many of us would normally define as “dead”, the high concentrations of glucose in the frog’s organs keep them from freezing solid. This means that as soon as they thaw, they are back to hopping around.
