ARKive.org:  Bringing endangered species to life

Hello, We’re ARKive, the world’s only centralized digital library home to thousands of images and films of globally threatened species.  We’ve partnered up with Endangered Species Chocolate’s Involved blog to give you a glimpse into the world of ARKive and the amazing imagery and facts you can find on the planet’s rarest species.  From the diving feats of the osprey to the tiny baby thorny devil, you can learn about these species and over 13,000 more on ARKive.

Since any reader of this blog likely has a sweet tooth, we thought we’d highlight some of the sleepiest critters on ARKive who could have definitely used a few Endangered Species Chocolate bars to stay awake…let’s see if you’re not yawning by the end of it!

ARKive’s Top Ten Sleepiest Species

One 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 to 170 meters or 500 feet deep down in the ocean.

A Sweet Sleeper.  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 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 incubation 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!

Down 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.

Submerged Snoozer.  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.

Daytime Dozer.  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, seels to have taken the opportunity to catch a few winks before bedtime.

Curled Up to Catch Zzzs… 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.

Cat-napping Koala.  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 while it yawned, the Thylacine could open its jaw wider than any mammal on the planet.  Are you yawning yet?
