ما هو الحيوان الذي يغير جلده كل عام

The animal that changes its body every year is the snake. It sheds its skin every year, sometimes multiple times, because as it grows, its old skin becomes tight and doesn’t stretch with it. If the snake doesn’t shed its skin, it can suffocate. The old skin is filled with insects and dust, so shedding it helps the snake clean itself. This process is necessary for the snake to grow and stay healthy.
