Question

How to identify a venomous and a non venomous snake by the pattern of biting?

Answer 1

Most poisonous snakes have a pupil that resembles a cat's; an oblong shape with peaked ends, like a slit in the center of the eye. Non-venomous snakes usually have round pupils. There is always the exception. The coral snake, a very venomous snake in the United States, has round pupils.
