Standing vs. Lying Down. It's a common misconception that cows don't lie down to rest and that they sleep standing up, just like horses do much of the time. In fact, cows actually lie down for up to 14 hours per day, standing up every few hours, stretching and then lying back down again.
While cows need relatively little sleep, giraffes sleep even less. On average, an adult giraffe sleeps just 1.9 hours per day. On the opposite end of the spectrum, brown bats sleep for 19.9 hours per day, giant armadillos sleep for 18.1 hours per day and North American opossums sleep for 18 hours per day.
