Review and images by Lanthanotus; edited by bmathison1972
Amongst the suborder of Serpentes (Snakes) with their quite uniform body plan, rattlesnakes make a somewhat exotic difference. Few species of snakes have keeled or largely overlapping scales which give the rattlesnakes’ skin a rather coarse appearance, some species even have small horns above their eyes, and all have small ridges above their eyes which bestows them the sinister look of all vipers.
