Life Cycle of the Frog: Egg Stage

Frogs lay thousands of eggs that do not have shells.  They are covered with a jelly-like substance that helps protect them from being eaten by creatures in the water.  The eggs stick together to form frog-spawn that floats to the top of the water.  A few days later the tadpoles hatch out.
