Tadpole with legs

The Life Cycle of a Frog

  • Egg

    A jelly-covered egg is produced in the water.
  • Tadpole

    About 10 days after the egg is fertilized, it hatches a tiny tadpole that uses its tail to swim.
  • Tadpole with Legs

    In about 9 weeks, the tadpole then begins to sprout legs.
  • Froglet

    As the tadpole continues to grow, its tail shrinks and its front legs begin to form in about 12 weeks. The lungs develop and its eyes and mouth begin to grow larger.
  • Adult Frog

    At the end of 16 weeks, the tail has disappeared and the froglet is now a frog!
