Did you know: giraffes only need as little as 30 minutes of sleep a day

giraffes sleep as little as 30 minutes a day. They are known for being among the animals that sleep the least.
Why do giraffes sleep so little?
Predators: Giraffes need to be alert to predators, so they sleep in short spurts.
Vulnerability: Giraffes are vulnerable while getting up from lying down, so they sleep standing up in the wild.
Diet: Giraffes spend a lot of time ruminating, or chewing partially digested food, which takes up most of their active day.
How do giraffes sleep?
Giraffes sleep in short naps, sometimes only a few minutes at a time.
Giraffes in zoos sleep more than giraffes in the wild, sometimes up to six hours a day.
Giraffes in zoos are more likely to sleep lying down, and they can enter deeper sleep cycles.
Giraffes sometimes sleep with their heads resting on their rumps, which is a vulnerable position associated with REM sleep
