The mammal with the shortest sleep cycle is the giraffe!

Le mammifère qui a le plus court cycle de sommeil est la girafe !

Giraffes need less sleep than any other mammal. In fact, they sleep between 10 minutes and 2 hours over a time span of 24 hours which is an average of 1 hour and 9 minutes of sleep a day.

Giraffes have adapted themselves to the environment where they live in order to stay awake as long as possible to protect themselves from predators.
