they start growing it when there born
As tadpoles grow they start to develop legs, a distinct head, and become more frog-like.
Amphibians grow legs and feet. If you look at tadpoles at about the three week stage, they start to develop their legs and feet while in the water
Frogs start out as tadpoles and then they develop into jumping frogs. They start life in water.
Tadpoles need to develop their lungs before they can come out of water (at the beginning of their metamorphosis they have only gills).
because once they grow out of the tadpole stage and into the frog stage, they no longer need them because they develop lungs
well they don't just breathe by their gills they also can breath by their mouthAnswer:It depends on the stage of their development. Ypounger tadpoles breathe only with internal or external gills. About the time their legs start to develop they start to develop lungs. Just before emerging from the water their lungs are developed enough to share the burden. When they emerge it's lungs only!
Then the front legs come out right behind the eyes. After that their tails start to shrink.
frogspawn turns into tadpoles which eventually turn into frogs.
Gradually they develop legs (usually the back pair first), lose their external gills and finally their tails.
No, legless tadpoles cannot eat flies.Specifically, a tadpole's diet answers to developmental stage. Before developing legs, a tadpole follows a vegetarian diet. Once legs develop, a tadpole is able to digest such insects as small crickets and flies.
Baby frogs and toads are called tadpoles. The tadpoles undergo metamorphosis and then grow up into toads and frogs. The tadpoles develop legs and lungs.
Tadpoles live in water, as they develop they grow legs and lungs which then allow the to live on land, as adult amphibians.
