The Sleeping Time of Different Animals
Animal’s sleep habits and resting time differ among species including human beings. Some mammals can sleep for almost a whole day and some for less than an hour that they can’t experience REM(Rapid Eye Movement). Some of them, like cows and horses, can do napping while standing up. Giraffes can stay awake for weeks without without taking nap. Dolphins can keep their one eye open to stay alert for approaching predators.
