Introduce snakes in English

I like a snake very much. She is very beautiful, but people are very afraid of her. A rattlesnake is a poisonous snake and a drug giant. Every time it molts, its tail will shed a layer of skin. Connected in many parts, it will be fixed like a small insect to attract birds. It can keep its body still (protect the natural color of the skin so that birds can't see it), only keep shaking its tail (like a small insect) and make a quack sound (that is, what is called "end"). If a bird approaches its tail, it will be a bird.
