Fatgs

Females often gather in communal dens to give birth and care for their young. Some females even look after unrelated young while the mothers take a break.1

Newborn snakelets measure 22 to 28 cm and are venomous from the moment they are born.1

Prairie rattlesnakes prefer a straight migration path, even in areas dominated by humans, because it gives them a better chance of survival.1

In Montana, the species reaches its largest size, with specimens sometimes exceeding 120 cm.1

In Canada, the species is listed as a species of special concern because its numbers have steadily declined since the 1930s.1
