Frogs lay eggs in water or wet places known as frog spawn. The eggs hatch into tadpoles that live in the water and have tails and gills. After 7-12 weeks the tadpoles grow hind legs and then front legs, their tails shrink and they develop lungs, allowing them to live on land as frogs. The newly emerged frogs eat insects and worms, find mates, and the females lay more eggs to continue the life cycle.

frog
• The eggs
• Tadpoles
• Frog lets
• Frog
3. The Egg
• Frogs lay their eggs in water or wet places. A
floating clump of eggs is called frog spawn.

5. The Tadpole
• The tadpole has a long tail, and lives in the
water. It is extremely vulnerable, and must
rely on its camouflage to protect it. The
tadpoles also face danger by being eaten by
other water animals. Sometimes the pond
dries up. As a result the tadpoles die.

7. Frog lets
• After seven weeks their hind legs begin to
grow. After nine weeks, front lets grow and
their tails are almost gone. After about twelve
weeks the tadpoles can swim to the surface of
the water and breathe in air.

9. The Frog
• Eleven weeks 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
way this is done varies depending on the
species. The female lays the eggs, the male
fertilizes them, and the whole process begins
again.
