Narration: Frogs lay their eggs in the water where they are fertilized and develop into embryos. <break time="3s"/> When embryos hatch they become free swimming and are called tadpoles.

Caption: Tadpoles develop into froglets and then adult frogs
Narration: After several days and still in the water, tadpoles develop legs and lungs and become froglets. <break time="3s"/> Froglets move onto land, loose their tail and become adult frogs where the life cycle continues.
