* Balance and stability: The tail acts as a counterbalance when the cheetah is running at high speeds.
* Steering: The tail can help the cheetah change direction quickly.
* Communication: The tail can be used to communicate with other cheetahs, for example, by raising it during a territorial display.
* Defense: The tail can also be used as a weapon to swat at predators.
So, the long tail is a key part of the cheetah's anatomy and helps them thrive in their environment.
