1 A Frog’s life

3 Life cycle of a frog First the frogs are like small round jellies.Then they become small tadpoles. Tadpoles are aquatic, lack front or hind legs, have gills for respiration and tails with fins for swimming like fish. They get water through the gills. There are some Poisonous tadpoles, such as Cane Toads. The frogs are called tadpoles for a week and then they become small frogs (froglets). First the frogs are like small round jellies.Then they become small tadpoles. Tadpoles are aquatic, lack front or hind legs, have gills for respiration and tails with fins for swimming like fish. They get water through the gills. There are some Poisonous tadpoles, such as Cane Toads. The frogs are called tadpoles for a week and then they become small frogs (froglets).

4 They have about 8–12 weeks like Froglet. In metamorphosis, tadpoles develop hind and then front legs, lose their gills, and develop lungs. The final stage of development from froglet to adult frog involves apoptosis (programmed cell death) of the tail. They have about 8–12 weeks like Froglet.

5 Young adults may leave water and disperse into terrestrial habitats, or continue to live in the aquatic habitat as adults. Almost all species of frogs are carnivores as adults, eating invertebrates such as insects, worms and spiders. A few of the larger species may eat prey such as small mammals, fish and smaller frogs. Some frogs use their sticky tongues to catch some flying insects like fly or a mosquito.

6 Others capture their prey, and force it into their mouth with their hands. However, there are a very few species of frogs which primarily eat plants. Adult frogs are themselves chased to be eaten by birds, large fish, snakes, otters, foxes, badgers, coatis, and other animals.
