What is a baby frog called?

A baby frog is called a tadpole or polliwog. It is the larval stage of the frog's life cycle. Tadpoles hatch from eggs laid in water and have a long, fin-like tail that they use to swim. They feed on algae and other small aquatic organisms. As they grow, they develop hind legs followed by front legs, and their tails are reabsorbed. Eventually, they leave the water and become fully developed adult frogs. The length of time it takes for a tadpole to develop into a frog varies depending on the species and environmental factors such as water temperature and food availability.
