The Puff Adder (Bitis arietans) is a venomous viper found throughout Africa and the Middle East. These snakes are very defensive, hissing loudly and taking in air to appear larger when threatened. Otherwise, they are naturally somewhat sluggish, ambushing prey which crosses their path instead of actively hunting.
The average size is about 1m (39.3 inches) in total length (body + tail) and very stout. This species is responsible for more snakebite fatalities than any other African snake.
