Fish live their whole lives in the water. Some fish lay eggs. Other fish are born live. A frog is an amphibian. It starts its life in the water and then moves onto land when it becomes an adult.
Well life cycles are quiet common for Salmon fish the cycle is FIRST the personification series the the delenar and when the get the chance they go to salmon HINT: its just like pooping
Fish do not go through metamorphosis,(changing completely, for example caterpillar - butterfly). so it's simple, eggs, then very small fish, then it keeps getting larger so to make a long answer...
