All animals need to breathe. The air contains a gas called oxygen which our bodies need to work.

💡 Fun Facts

  • Fish get their oxygen from the water using special gills on the side of their head.
  • Worms can breathe through their skin, but only if it stays damp!
  • A sloth can hold its breath for 40 minutes underwater, which is much longer than a dolphin!
