The document describes the life cycles of several common animals including frogs, butterflies, mammals, and birds. It explains that frogs undergo metamorphosis from egg to tadpole to froglet to adult frog. Butterflies also experience complete metamorphosis through the stages of egg, caterpillar, chrysalis, and butterfly. Mammals are born alive rather than hatching from eggs, while birds develop from eggs.
