Wikipedia about rattlesnake
Rattlesnakes are a group of venomous snakes, genera Crotalus and Sistrurus. They belong to the class of venomous snakes known commonly as pit vipers. Rattlesnakes are characterized by the presence of a "rattle" at the tip of the tail used to warn off predators and threats.
Overview
There are approximately fifty species of rattlesnake, with numerous subspecies. They receive their name for the rattle located at the tip of their tails. The rattle is used as a warning device when threatened. The scientific name Crotalus derives from the Greek, κρόταλον, meaning "castanet". The name Sistrurus is the Latinized form of the Greek word for "tail rattler" (Σείστρουρος, Seistrouros) and shares its root with the ancient Egyptian musical instrument, the sistrum, a type of rattle. Rattlesnakes are also endangered because of humans killing them. Most rattlesnakes mate in the spring. All species give live birth, rather than laying eggs. The young are self-sufficient from birth. As they do not need their mother after birth, the mother does not remain with her young.
Prey
Rattlesnakes consume rodents and other small animals, such as rabbits, rats, and mice, subduing their prey quickly with a venomous bite as opposed to constricting. Rattlesnakes have also been known to eat small mammals, like foxes, cats or dogs.Fact: date=July 2008 The venom stuns or kills typical rattlesnake prey immediately. A rattlesnake will follow prey that does not quickly succumb to the venom and attempts to escape. They are specially known to strike at distances up to two-thirds their body length.
Predators
Rattlesnakes are prey for kingsnakes, roadrunners, pigs,1 hawks, and eagles. They have been harvested as human food, such as at the Rattlesnake Round-Up in Sweetwater, Texas.
Reproduction
Although many kinds of snakes are oviparous (lay eggs), rattlesnakes are ovoviviparous -- the female retains the eggs in her body until they hatch and the young emerge alive. Baby snakes are ready to go as soon as they are hatched or born. There is little to no parental care of the newborn snakes.

Safety and identification

Different species of rattlesnake vary significantly in size, territory, markings, and temperament. If the rattlesnake is not cornered or imminently threatened, it will usually attempt to flee from encounters with humans, but will not always do so. Bites often occur when humans startle the snake or provoke it. Those bitten while provoking rattlesnakes have usually underestimated the range (roughly two-thirds of its total length) and speed with which a coiled snake can strike (literally faster than the human eye can follow). This can be particularly surprising since the snakes can strike without pulling their body back. This reflex hasn't been recorded in any other species. Heavy boots and long pants reinforced with leather or canvas are recommended for hikers in areas known to harbor rattlesnakes.
