Rattlesnakes are venomous snakes native to North America and a few other parts of the Northern Hemisphere. They get their name from the rattle located at the tip of their tails that is used as a warning device when threatened. The rattle is a set of rings on the tip of their tail. When vibrated, the rattle creates a hissing sound that warns off predators. Rattlesnakes use their venomous bite to catch and kill prey such as mice, rats, small birds and other small animals.
