About
The eastern diamondback rattlesnake is a species of pit viper endemic to the southeastern United States. It is the largest rattlesnake species and the heaviest venomous snake in the Americas, reaching lengths of up to 2.4 m (8 ft) and weights exceeding 15 kg (33 lb). It is known for its distinctive diamond-shaped dorsal pattern and large rattle. Despite its potent venom, it is generally docile and prefers to avoid confrontation.
Fun Fact
Eastern diamondback rattlesnakes add a new segment to their rattle each time they shed their skin (2-3 times per year), but the oldest segments break off, so you can't actually age one by counting rattle segments.
