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.
The giraffe has one of the shortest sleep requirements of any mammal, which is between 10 minutes and two hours in a 24 hour period, averaging 1.9 hours per day. Groups of giraffes are called herds, although they differ from the herds of most other animals. A giraffe herd can consist of anywhere from 2 to 50 animals.
