Is there mice without a tail?

No, there are no mice without a tail.

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.
