πŸ’‘ Fun Facts

  • A single frog can lay thousands of eggs in a jelly-like clump called frogspawn.
  • During metamorphosis, a tadpole's body is completely rebuilt: it absorbs its tail for energy, grows lungs to replace gills, and its diet changes from plants to insects.
  • A tadpole lives entirely underwater, breathing with gills like a fish.
