The eastern diamondback rattlesnake is a pit viper that lives in the southeastern United States. It is the largest rattlesnake species and one of the heaviest venomous snakes in the Americas. Its diamond-patterned back and loud rattle make it easy to recognise, and it is widely regarded as one of the most dangerous venomous snakes in North America.1

jakin beharrekoa

Datuak

It is the largest rattlesnake species. One specimen shot in 1946 measured 2.4 m and weighed 15.4 kg.1

In proportion to its length, it has the longest fangs of any rattlesnake, with fangs of over 25 mm expected in a 2.4 m adult.1

It can strike its prey within a tenth of a second.1

It can swim well and has been seen crossing water sometimes miles from land.1

Although mainly ground-dwelling, it has been spotted up to 10 m above the ground in bushes and trees.1

Males are usually larger than females, which is a rare pattern called reverse sexual size dimorphism.1

Mito-hauslea

Mitoa: The eastern diamondback must rattle before it strikes.

Egia: It can strike while completely silent. Some individuals stay quiet even when approached closely.1
