Rattlesnakes
They do not move, but are mainly hidden behind bushes, so you have to be careful where you are going. They are poisonous.
Notes
Rattlesnakes are a group of venomous snakes, genrea Cotalus and Sisturus, that comprise over fifty species. They belong to a group of snakes known as pit vipers, snakes with 'pits' located on their heads that allow them to detect variations in heat. The rattlesnake gets it's name from the distinctive collection of nested, hollow scales at the end of their tails, which rattle when the animal is agitated. Rattlesnakes are highly venomous and have been known to kill humans. They are farmed and hunted for their skin and meat, used for clothing and food respectively. Rattlesnakes are located across the United States and also occur in Canada and Central and South America.
