TextNap Time
Does a good nap make you feel better? Sperm
whales think so. They take short power naps to
recharge their energy. Pods of sperm whales float like
large exclamation points in the water. These snoozing
mammals rest for up to twelve minutes. Scientists
believe they may even dream while napping.
More About Sperm Whales
The sperm whale is the largest of the toothed whales.
Males can grow to be from 50 to 60 feet (15 to 18
meters) long. They also have the largest brain of any
animal on Earth. It is more than five times heavier
than a human brain.
