When the weather is extremely hot or cold, snails can stay inside their shell for long periods. In some extreme cases, where there are long periods of extreme weather, snails will sleep for 3 years, although it is not very common. If you put it into perspective, a snail could spend one-third of its life sleeping.
A sloth is a very lazy animal. It sleeps for around 18 hours a day. It eats the leaves from the tree on which it sleeps.

Brown Bat/Sloths – 20 hours
Bats are known for only emerging during the night time, but surprisingly, brown bats are still only awake for 4 hours of the night. They sleep for a whopping 20 hours (83%) hanging upside down. Due to lack of food they also spend 6 months of the year in hibernation.
However, unlike other mammals, adult dolphins and whales are able to go without sleep for a month.
Koalas. Hats off to the (somewhat disputed) king of sleep: the Koala bear. They've been reported to sleep up to 22 hours a day in captivity, over 90% of their lives. In the Australian wild, that figure may be closer to 14.5 hours of sleep daily, boosted by 5 additional hours of rest and inactivity.
Bullfrogs… No rest for the Bullfrog. The bullfrog was chosen as an animal that doesn't sleep because when tested for responsiveness by being shocked, it had the same reaction whether awake or resting.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
The koala holds the accolade for 'the animal that sleeps the most'. This Australian icon sleeps for 20-22 hours each day (sounds good to us), making it the sleepiest creature in the animal kingdom.
Lithobates catesbeianus is an animal that cannot sleep.
Cats and dogs have a sleeping cycle of 12 hours a day.
Always watching.
The mammal that sleeps the least is the African bush (savannah) elephant Loxodonta africana, which has been found to sleep only two hours per day on average – less than any other mammal species so investigated.
Chimps sleep around 9.5 hours out of every 24. Cotton-top tamarins sleep around 13. Three-striped night monkeys are technically nocturnal, though really, they're hardly ever awake — they sleep for 17 hours a day.
Sloth. When people think of the word “lazy”, sloths are often one of the first animals to come to mind, and it's not surprising. They sleep for up to 20 hours a day and are known for being extremely slow-moving.
In the case of the elephant, in fact, it's impossible. Unlike most mammals, the bones in elephant legs are all pointed downwards, which means they don't have the "spring" required to push off the ground.
One of the largest species of armadillo, the giant armadillo (Priodontes maximus) are powerful and covered with tough bony scales. Another nocturnal animal who needs to sleep a lot, this creature can sleep for 16-18 hours a day. Giant armadillos essentially spend all day in their burrow, sleeping the day away.
Unlike humans, snails don't abide by the rules of night and day. Generally, snails will sleep on and off in between periods of 13 to 15 hours. Afterwards, they experience a sudden jolt of energy for the next 30 hours, where they get all their snail chores done! How Can You Tell If a Snail Is Asleep?
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
The first animals that arose seem to have literally had potty mouths: Their modern-day descendants, such as sea sponges, sea anemones, and jellyfish, all lack an anus and must eat and excrete through the same hole.
According to research, while trees may not sleep in the same way animals do, they do relax their branches during nighttime, which suggests that yes, trees have activity-rest cycles. These cycles can also vary depending on the tree species.
