How can you tell the difference between a poisonous and nonpoisonous snake?
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.
