Rattlesnakes
are found from Canada to South America, usually in arid regions. Most
species eat small animals, primarily rodents; small or juvenile rattlesnakes
depend largely on lizards. All species bear live young, usually in
broods of about a dozen.
Like
other snakes, rattlesnakes
cannot tolerate extreme heat or cold. In hot areas they become
nocturnal, avoiding the heat of day in protected shelters. In winter
they congregate in rockslides or crevices to hibernate. All
rattlesnakes are venomous and
dangerous.
