Frog eggs hatch into tadpoles that live in water, where they face dangers from predators. Over about 5 weeks, tadpoles grow hind legs and lungs as they transform into small frogs. Once fully developed after 11 weeks, adult frogs with legs and lungs emerge from the water to live on land, where they eat insects and reproduce by laying eggs that hatch into new tadpoles, continuing the life cycle.

Introduction to the life cycle of frogs, highlighting the stages of development.
Frogs lay eggs in water, creating frog spawn, a protection mechanism against predators.
Tadpoles live in water, rely on camouflage, and face dangers like predators and drying ponds.
After five weeks, tadpoles grow hind legs and develop lungs, transitioning to frogs.
As they mature, young frogs shed skin, develop wider mouths, and reduce tail size.
At eleven weeks, a fully developed frog emerges, transitions to land, and starts mating.
Recap of the frog life cycle phases, from spawn to adult.

- 2. Today we are goingto look at the life cycle of a frog. This picture shows the different stages of development. Let’s have a closer look.
- 3. Frog Spawn Frogs laytheir eggs in water or wet places. A floating clump of eggs is called frog spawn. This large and slippery mass of eggs is too big to be eaten. This is nature's way of protecting them.
- 4. Tadpole The tadpole hasa long tail, and lives in the water. It must rely on its camouflage to protect it. The tadpoles also face danger by being eaten by other water animals. Sometimes a pond dries up and the tadpoles die.
- 5. Getting bigger After aboutfive weeks the tadpole begins to change. It starts to grow hind legs. Behind its head, bulges appear where the front legs are growing and its tail becomes smaller. Lungs begin to develop, preparing the frog for its life on land. Froglet
- 6. A young frog Overtime, the tadpole becomes even more froglike. It has shed its skin and lips. Its mouth widens, and it loses its horny jaws. The tail becomes much smaller, and the legs grow. Its lungs begin to work.
- 7. An adult frog Elevenweeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water. This frog will live mostly on land, with occasional swims. The tiny frogs begin to eat insects and worms. Eventually, it will find a mate. The female lays the eggs, the male fertilizes them, and the whole process begins again.
