All mice species, from the common house mouse to the rare and endangered ones, have tails.
Tails are essential for mice:
* Balance and Agility: Tails help mice maintain balance, especially when running and jumping.
* Communication: Mice use their tails for communication. For instance, they can raise their tails as a sign of aggression or fear.
* Sensory organ: Mice's tails contain sensory receptors that help them detect changes in their environment.
Note: There are some rodent species, like the jerboa, that have extremely short tails. However, they still have a tail, even if it's barely visible.
