We’ve all had those mornings where we just want to hit the snooze button for five more minutes and most people would agree that some days are harder to get out of bed than others. Well, you may be surprised to learn there are species in the animal kingdom that just might agree with you.
We’ve compiled our top ten list of ARKive’s sleepiest critters…let’s see if you are still yawning by the end of it!
Wiped out fellow
I would be tired too if I were capable of impressive diving feats like the gentoo penguin who can pursue prey up 170 metres or 550 feet deep down in the ocean.
Although taking a moment to catch up on some sleep here, the Arctic fox is usually always on the search for food and amazingly, can reduce its metabolism by half, while still being active, to help conserve energy while on the hunt.
Sprawled out slumber
It’s well known that most bears hibernate through the winter months but sometimes it’s worth a reminder about how truly unique this process is. Once brown bears enter their hibernation period, they don’t eat, drink, urinate or defecate for up to six months! Could you imagine not getting out of bed for anything for 6 months?
Chameleons catch forty winks
It seems as though Parson’s chameleons start off as sleepy critters. With one of the longest incubations periods in the reptile world, it takes a whopping 20 months for a Parson’s chameleon egg to hatch. I guess if I had a nice safe place to sleep, I wouldn’t be in a hurry to hatch either!
Out for the count
It’s not surprising to catch all these big cats sleeping in the middle of the day. Lions are inactive 20 out of 24 hours a day and reserve their energy for the cool and darker times of day, such as sunrise and sunset, to hunt.
Manatees need to come up for air approximately every 20 minutes or less making them the top napping species on the list. Since manatees never leave the water, they don’t experience long periods of slumber like humans and so frequent, short bouts of sleep while resting on the ocean floor are enough for them.
Although most owls are nocturnal, meaning they are active at night and mostly inactive during the day, the little owl is actually diurnal and prefers to do most of its hunting during the day. This little owl, however, seems to have taken the opportunity to catch a few winks before bedtime.
Curled up to catch z’s
The dormouse is such a sleepy creature that its name is thought to derive from the French word ‘dormir’ meaning ‘to sleep’. When ready to begin hibernation, which can last up to 7 months, the dormouse enters a state of extreme torpor where its body processes slow to a fraction of their normal rate.
Another sleepy species, the koala spends a vast majority of its time snoozing away and even when awake, it’s a very sedentary species. You’ll find koalas often catching Z’s while balancing on branches in trees well out of harm’s way.
What a yawn!
Although extinct, we still know some very interesting facts about this species and that when it yawned, the thylacine could open its jaw wider than any mammal on the planet. Are you yawning yet?
