  5. Life Cycle Main Menu

  6. Eggs • Frogs lay their eggs in water or wet places • Floating clumps of eggs are called frog spawn • Once laid, the eggs are surrounded by a jellylike covering to protect them Main Menu

  7. Tadpole • After 21 days the embryo leaves the jelly shell and attaches to a weed in the water • The embryo grows until it is big enough to break free into the water • This can take from 3 days to 3 weeks depending on the species of frog Main Menu

  8. Tadpole with legs • After about 5 weeks, the tadpole starts to grow hind legs • This is followed by the growth of forelegs • The tails become smaller • Lungs begin to develop • Mouth widens Main Menu

  9. Adult Frog • 11 weeks after an egg is laid, a fully developed frog emerges from the water. • The frog will now live mostly on land, but returns to the water to swim. Main Menu

  10. Interactive Life Cycle What is each part of the life cycle (i.e., adult frog, tadpole, etc.)? Find out by moussing over the picture.
