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.
