There are several animals with unique sleeping habits. Here are a few examples:
Giraffes: Giraffes only sleep for about 30 minutes a day, usually in short naps that last only a few minutes at a time.
Dolphins: Dolphins sleep with one half of their brain at a time, while the other half remains awake. This allows them to stay conscious enough to surface for air while still getting some rest.
Elephants: Elephants sleep standing up, often leaning against a tree for support. They also have the shortest sleep cycle of any mammal, averaging only about 2 hours of sleep per day.
Bats: Bats are nocturnal animals that sleep upside down. They hang from their roosting spots with their feet and use their wings to cover themselves like a blanket.
Sloths: Sloths are known for their incredibly slow metabolism, which means they move very slowly and sleep for up to 20 hours a day. They often sleep hanging upside down from trees.
