Giraffes sleep for about 20 minutes per day in the wild, broken up into
short segments. They tend to spend the majority of their time eating,
hunting for food or allowing the food they have consumed to digest. The
main predators of the giraffe are lions and humans, and they stay awake to
keep as alert as possible to protect themselves. When a giraffe does sleep,
it generally happens during the day while standing with its eyes open,
because it is the most vulnerable to attacks when its throat is exposed.
Giraffes typically lay down only at night, but it is often more for resting
rather than for sleeping.
