2. Brown Bats
Could it be? 20 hours a day? Yes, brown bats are awake for only 4 hours of the day and love to sleep, some 83% of the time. Hanging upside down, and only emerging during the night, these bats hibernate half the year because of lack of food. Sloths also sleep for the same amount of time.

An arboreal animal, koalas grab the top position for being the sleepiest animal in the world. Found only in Australia, they live mostly on eucalyptus trees, and sleep about 22 hours a day. When awake, they spend quality time only on eating.
Though many animals spend more than half of the 24 hours of the day sleeping, that doesn’t mean they are lazy. They are actually very active when awake. Some animals do rest half-asleep, and some seem to be at rest but are actually fully conscious.
Scientifically, a good sleep, and rest, is essential for a healthy body and gives it a chance to repair. Talking of humans, it really is important to ensure that you get good sleep, helping you to get over your worries and to dispel the tensions of your day-to-day life.
