How long does it take for tadpoles to grow into frogs?
Generally in America, eggs laid in a smaller body of water (a road rut) the eggs will evolve from a creature that has gills and is entirely needful of water to live into one that has no gills and is in need of lesser degrees of water, in about two-three months (green frog, pickeral frog). In a larger body of water–pond–the same species may take another month or more. The above process also depends on the water not becoming too warm or drying up or being polluted. Some species (bullfrog, in a lake ) can remain a tadpole for two years or more. The tiger salamander’s tadpole (axolotl) in a lake where it is impossible to leave the water (steep shoreline) may retain its gills and breed. Some (Sumatra Toad) may carry on its metamorphosis within the parent and be born as a “baby” frog.
