Why does a rabbit need its tail to survive?

A rabbit's tail serves several important functions that contribute to its survival. Primarily, it acts as a signaling device; when a rabbit senses danger, it raises its tail, which can alert other rabbits in the vicinity to flee. Additionally, a rabbit's tail helps with balance and agility while navigating its environment, allowing for quick turns and evasive maneuvers. Furthermore, the tail can also help in thermoregulation, assisting in keeping the rabbit cool in warmer temperatures.
