Details: This poster shows a rattlesnake in some grass. It appears ready to strike with the top part of its body off the ground in an 'S' shape. Its rattling tail is also visible.
Rattlesnakes are a group of nearly thirty species of venomous New World snakes. They are named for the rattle found at the tip of their tails that is used as a warning device when threatened. Rattlesnakes feed on rodents and other small animals, subduing their prey by striking them quickly with a venomous bite as opposed to constricting. Most species of rattlesnakes have hemotoxic venom, while others have neurotoxic venom.
