* Communication: Mice can use their tails to communicate with each other. They might flick their tails to show excitement or raise them to signal danger.
* Sensory organ: The tail has sensory receptors that help mice feel their surroundings and detect changes in temperature.
* Temperature regulation: Their tails can help them regulate their body temperature by dissipating heat.
* Defense: A mouse can use its tail to help steer itself when escaping a predator. Some mice even have a prehensile tail that can wrap around objects, giving them extra grip.
Overall, a mouse's tail is a surprisingly versatile appendage that plays a vital role in its life!
