* Balance and hopping: The tail is crucial for balance, especially when hopping. It acts like a counterweight, helping the kangaroo stay upright and change direction quickly. Without it, the kangaroo would struggle to hop effectively and could easily fall over.
* Jumping power: The tail helps propel the kangaroo forward when it jumps. It acts as a third leg, pushing off the ground to increase the distance and height of the jump.
* Defense: The tail is used as a weapon, especially against predators. A kangaroo can strike with its tail, causing pain and deterring attackers.
* Communication: Kangaroos use their tails for communication. They wag it when happy or excited, and hold it still when feeling threatened.
So, a kangaroo that loses its tail would have a very difficult time surviving. They would be less agile, less powerful, and more vulnerable to predators. It's unlikely they would live very long.
