The diagram shows the different stages in the life of a fog in stream .
In general ,it can be seen that there are eleven stages in the development of the fog , from egg to mature adult creature .
The life cycle of the fog begins when femele adult lays eggs , eggs become black embryo which is covered white liquid . Then they become tadpoles , following this , they clinging to water plant and reside a few days in the pond . following this step , external gills evolve and emerge to breathe in tadpoles ,their tail keeps on growing ,and hindlegs begin appear on its back , more specifically , under head . In this period , fog reside from food stored in the tail , and then ,front legs begin appear , tail still long .
During the many stage of life cycle ,fog begins changing their skin colour to the green , and also , tail become shorter and appear somenew spots , during young period . After this long-term period , finally emerge adult fog .
