Some snakes are poisonous, or venomous, such as the rattle snake, cobra, and eastern green mamba.
They have fangs which bite into their prey and inject poison into the victim. Other snakes, such as the boa constrictor and the python kill their prey by crushing it. Most snakes can dislocate their jaw, allowing them to swallow prey much larger than themselves.
