Uracoan rattlesnakes are nocturnal solitary snakes that give birth to up to 10 young between 120 and 160 days after mating. Their diet is primarily made up of small lizards, but expansion of agricultural activities has introduced small rodents into its diet. Their life span is between 15 to 20 years and they are a shade of pale olive green, rust brown, or gray with numerous white-tipped scales scattered on their head and body. Unlike other Crotalus species, it can only be found in a specific ecological niche of small relictual forested areas with a specific microclimate. Their venom has both neurotoxic and hemorrhagic components.
