Only some snakes are poisonous | Non poisonous snakes have oval shaped head
Not all snakes are poisonous. Only some species of snakes are poisonous. Based on the shape of snake’s body, one can know whether it is poisonous or not. Non poisonous snakes have their head in oval or spherical shape. But poisonous snakes have their head in triangular shape. Thus the shapes of heads of poisonous and non poisonous snakes differ from each other. Moreover, poisonous snakes have big fangs where as the non poisonous snakes don’t have fangs at all.
Another important thing is that when a poisonous snake bites a person then prints of the two fangs are formed clearly on the victim’s skin at bitten place. But in the case of bite of a non poisonous snake, only prints of the small teeth are formed. It is an important point to be noticed that the retina of the non poisonous snakes will be in circular shape. Also based on the fins on the head, tail and on the stomach, poisonous snakes can be identified.
