What is the function of a frogs gills?

Frog gills, primarily present in their larval stage as tadpoles, serve the function of extracting oxygen from water for respiration. These gills allow tadpoles to breathe underwater, facilitating their growth and development. As frogs mature and undergo metamorphosis, they lose their gills and develop lungs for breathing air. Thus, frog gills are crucial for the aquatic life stage of the amphibian's life cycle.
