Eastern Diamondback Rattlesnake Crotalus adamanteus

The Eastern Diamondback Rattlesnake is a venomous pit viper native to the southeast United States around Florida and areas immediately north. It has several other common names.

It can grow to well over 7 feet (nearly 2.5 metres) and is the largest of the Rattlesnakes. It usually has a white hatching pattern or diamond shapes on a dark grey or brown background. Its main diet is small mammals (up to rabbits and squirrels) but its bite can be fatal to humans and it doesn't always rattle its tail in warning before striking.
