What is the sleepiest animal on the planet? (Hint: your teenaged child is not the correct answer.)
An arboreal animal, koalas grabs the top position for being the sleepiest animal in the world. Found only in Australia, they live mostly on eucalyptus trees, and sleep about 22 hours a day. When awake they spend most of their quality time eating.
And a human baby is in the top seven sleepy animals—at number five. Human beings are animals—some more than others. A human baby under the age of one year can sleep 16 hours a day.
