There are several species of snakes dangerous to humans in the southern states that are frequently encountered. These are the copperheads, cottonmouths and rattlesnakes. These snakes are grouped as pit vipers; that is, snakes that have a heat sensitive hole or pit between the eye and nostril and elliptical-shaped pupils. The cottonmouth by far is the most aggressive of the pit vipers. Each species has distinct markings that enable easy identification (Figures 222-227). People that work alone in remote wooded places should wear protective boots or leggings and be familiar with local medical protocols for treating snake bites. |
