During this stage, tadpole matures and develops – Forms front and back legs – Tail is still intact to assist in swimming – LUNGS begin to develop Photo Source:

Froglets legs and arms are more defined Tail is smaller Transition from water to land – Froglet explores dry land Froglet is dependent on oxygen to live and breathe – Lungs are fully developed Photo Source:
