Rattlesnakes have a deadly reputation, but only strike humans if cornered or threatened. They are more likely to flee than attack. None but the bravest predators should ignore the vibrating rattle, as these snakes can inject a venom that stuns and even kills. Small mammals should be particulary wary as they will be caught with precision, swallowed whole and digested. The 30 or so species in this fascinating group are found only in the Americas. If you can identify all the different skin patterns and colours then you are probably too close for comfort...
