"The life cycle of a frog consists of three stages: egg, larva, and adult. As the frog grows it moves through these stages in a process known as metamorphosis. Frogs are not the only animals to undergo metamorphosis, most other amphibians also undergo remarkable changes throughout their life cycles, as do many species of invertebrates."
This guide is broken down into four pages: home (or life cycles in general), eggs, tadpole and adult frog. For example if you are looking for information on the stage of a tadpole just open that page up and there will be information and interactive components pertaining on tadpoles. Also if any of the titles say "CLICK ME", click it and you will be directed to an interactive page.
