Eastern Diamondback Rattlesnake

The Eastern Diamondback Rattlesnake is the largest rattlesnake species and the heaviest venomous snake native to North America. It is found throughout the coastal plain of the southeastern United States, where it has become increasingly threatened by habitat loss and fragmentation.

Its bold diamond pattern and formidable size make it one of the most recognizable and ecologically significant predators in its native pine flatwoods and scrub habitats.

• Series of large, dark brown to black diamond-shaped blotches outlined in cream or yellow running down the back
• Heavy, thick body with a relatively large, triangular head distinct from the neck
• Prominent rattle at the tail tip, though rattles can occasionally break off
• Vertically elliptical pupils and heat-sensing facial pits between eye and nostril
• Two pale diagonal stripes on the side of the face, bordering the eye
• Distinguished from other rattlesnakes in its range by its much larger size and bold, well-defined diamond pattern

Inhabits dry pine flatwoods, sandhill scrub, coastal dune habitats, and palmetto thickets throughout the coastal plain of the southeastern United States, often using gopher tortoise burrows and stump holes for shelter.

Primarily active at dusk and during the day in cooler months, becoming more nocturnal in hot summer weather. An ambush predator that preys mainly on rabbits, rodents, and other small to medium mammals, striking from a coiled position. Viviparous, giving birth to live young. Generally reluctant to strike unless cornered, often relying first on its rattle as a warning.
