[00:07.79]Let's talk.
[00:09.29]Hello! Welcome to "About Animals."
[00:12.64]Today we're going to talk
[00:14.62]about the life cycle of a frog.
[00:16.74]Adult frogs lay eggs in spring.
[00:19.99]After about two weeks, tadpoles come out.
[00:22.76]About five weeks old, they have back legs.
[00:27.52]About ten weeks old, they have front legs, too.
[00:31.67]Their tails become short and then they are called froglets.
[00:35.65]The froglets eat small animals such as flies and then become young frogs.
[00:41.53]They live on land for two or three years and become adults.
[00:44.98]Then they go back to water to lay eggs.
