Frogs leave their fertilised eggs in
                                                          damp places. Out of these eggs
                                                          hatch tadpoles that have large heads
                                                          and tails. In time, the tadpoles
                                                          develop arms and legs and the
                                                          infants take on the shape of frogs.
                                                          Finally, development ends as the
                                                          tails disappear.
