               Notes:

                   •  The frogs lay hundreds of eggs in water.

                   •  When the eggs hatch, tiny young known as tadpoles, come

                       out.
                   •  The tadpoles start swimming in water.
                   •  A tadpole has a tail and gills.

                   •  In a span of 12-16 weeks, a tadpole fully develops into an
                       adult frog.

                   •  During this period, the gills of a tadpole are replaced by
                       lungs, the tail disappears and other organs also develop.
