Does the squirrel have spikes on tail?

No, squirrels do not have spikes on their tails. They have fluffy, bushy tails that are covered in fur.

The tail is a very important part of the squirrel's body, as it helps with:

* Balance: The tail acts as a counterbalance, helping the squirrel to move around in trees and on the ground.

* Communication: The squirrel can use its tail to signal other squirrels, such as by flicking it or raising it when it feels threatened.

* Warmth: The tail can also help to keep the squirrel warm in cold weather.
