Eastern Diamondback Rattlesnake

Eastern Diamondback Rattlesnake Introduction

Crotalus adamanteus, commonly known as the Eastern Diamondback Rattlesnake, among other names, is a venomous pit viper belonging to the family Viperidae. This specific species of rattlesnake is endemic to southeastern United States. It is the heaviest, though not longest, venomous snake in America and is also the largest rattlesnake and can grow up to 2.4 meters (8 feet) in length and can weigh up to 4.5 kg (10 pounds).

The rattle of the Eastern Diamondback is well developed and can be heard from relatively far away. When threatened, it raises the anterior half of the body off the ground in an S-shaped coil and can strike to a distance of at least a third of its body length. Many will stand their ground and may strike repeatedly, but if given the opportunity, they will usually retreat while facing the intruder and moving backwards towards shelter, after which they disappear.
