'''Snakes''' are long, [[limb]]less, [[scale|scaly]] [[reptile]]s which slither upon the ground and sometimes swim in [[water]]. Some snakes (about one third of species) are [[poison]]ous (specifically, [[venom]]ous). Snakes are abundant in warmer climates, and most of them are quite harmless to man. The fastest moving land snake is the [[Black Mamba]], which can move up to 7 miles per hour.
