Tails are incredibly versatile. Why would your alien have tails?

Animal tails come in all shapes and sizes, and serve a variety of purposes. Fish use their tails to swim and maneuver through the water, while some primates, like monkeys, have prehensile tails that they can use to grasp branches and hold onto objects. Squirrels also use their bushy tails for balance as they leap from tree to tree. Some birds, like the sparrow, use their tails to steer and brake while in flight. And let’s not forget about the rattlesnake, which uses its tail to warn off potential victims. So whether it’s for movement, balance, or display, tails are a fascinating part of the animal kingdom!
