Today, more than 60 species of snake live in Iran including this Persian ratsnake named E. Persica .
Not all snakes are poisonous, however. In fact, most are not. Snake is a very useful animal. It kills rodents and other pests, and this way it can prevent disease by eliminating the carriers of harmful germs.
The Elamites, who established a great civilization in the southwestern Iran, respected snakes. The Elamites thought snakes had magical powers. Thus the Elamite kings always wore a snake-shaped crown.
