What are two functions of a tadpole's tail?

A tadpole's tail serves primarily for locomotion, allowing it to swim efficiently through water as it seeks food and avoids predators. Additionally, the tail plays a crucial role in balance and stability while swimming, helping the tadpole maneuver effectively in its aquatic environment. As the tadpole matures into a frog, the tail is gradually absorbed, reflecting its transition to a terrestrial lifestyle.
