The story
A three-toed sloth moves so slowly that algae grows in its fur, which helps it hide. A koala dozes most of the day digesting tough leaves, an edible dormouse can hibernate for months, and a giant tortoise strolls through a life that can last over a century.
What you'll learn
- Leaves hold little energy, so leaf-eaters save energy by moving slowly.
- Moving slowly makes a sloth very hard for predators to spot.
- Hibernation lets an animal wait out a season with almost no food.
- Kid takeaway: saving energy is a survival strategy, not laziness.
