Fun Facts

  • Did you know? The nostrils in your nose help you breathe air. Whales breathe through nostrils, called blowholes, too. But they're located on the tops of their heads!
  • Humpback whales hunt with bubbles. They work together to blow bubbles that surround and trap their prey.
  • Some whales don’t need to eat for most of the year. They live off stored fat for half the year while they travel from their tropical homes all the way to the Antarctic!
When whales go underwater, they hold their nostrils shut!
