At Happy Beds, we're passionate about animals and sleep. So naturally, we have a few questions - how do animals sleep? Do animals sleep a lot?
Animals sleep for different lengths of time due to various reasons: habitat, genetics, vulnerability...the list goes on and on. But out of every species what animals sleep for the longest? And why?
We've done some research and compiled a list down below of 5 animals that like to snooze for ages and 5 animals that prefer to stay awake. Take a look below!
5 Animals That Sleep the Most
Koala: 20-22 hrs
This sleepy animal doesn't get much energy from its diet of eucalyptus leaves. This is because eucalyptus is toxic to many animals and so a koala has to work hard to digest it. That's why a koala has to sleep so much!
Sloth: 15-20 hrs
There are many different reasons why this sleepy animal snoozes for so long; they like to stay hidden from predators, have a slow metabolic rate and require little food to survive. For a sloth, taking it slow is the best way to live comfortably.
Brown Bat: 19 hrs
A brown bat is a nocturnal animal, so will sleep during the day and hunt by night. If a brown bat doesn't find enough food to eat then it will have to slow down its body rate to conserve energy. This means it will have enough energy to forage the following night.
Giant Armadillo: 16 hrs
Another nocturnal animal, a giant armadillo sleeps in an underground burrow. This creature is not social and instead prefers to spend its time sleeping! In the wild, a giant armadillo can sleep for up to 16 hrs and up to 18 hrs in captivity.
Python: 18 hrs
A python will sleep for long periods during the day to preserve its energy. This nocturnal creature will then go hunting for prey throughout the night. A python doesn't have eyelids which means they sleep with their eyes wide open. Creepy!
5 Animals That Sleep the Least
Sperm Whale: 5-15 mins breaks
This sleepy animal is an interesting one! A sperm whale will sleep for short breaks vertically to prevent it from drowning. This funny sleeping position is called 'logging' due to the resemblance to a drifting log.
Giraffe: 30 mins a day
A giraffe will only sleep for short bursts of up to 30 minutes a night to protect itself from predators. If it slept for any longer it would become vulnerable. Their vulnerability is also why a giraffe tends to snooze on their feet rather than laying down.
Elephants: 2 hrs
An elephant sleeps so little to avoid any potential danger. Elephants have been known to go up to 46 hrs without sleep to avoid poachers and predators! These sleepy animals also rest in groups, with one group sleeping and the other watching for any potential dangers.
Dolphins: 2 hrs
How do dolphins sleep? With half of their brain of course! A dolphin needs to be constantly awake to be able to breathe. To get some rest, a dolphin will sleep with only half of its brain at a time. After 2 hours, it will switch sides, allowing the active part of the brain to rest.
Walruses: 2 hrs
A walrus will spend a lot of time continuously swimming, so sleep in short bursts usually floating in the sea or leaning against something. Typically seen as a sleepy animal that can snooze anywhere, this creature is the opposite of lazy and stays awake for long periods!

Sadly, a lot of animals struggle to sleep because they're in trouble of becoming extinct. With our partnership with wildlife charity Born Free, we want to spread awareness for innocent creatures that are at risk.
