Why do tadpoles 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
Do tadpoles breathe by gills only?
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.

What do amphibians develop as they grow besides their lungs?
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
