Hidden in the grasses and the dead leaves on the ground, it is quite difficult to find the puff adder. The pattern of its skin provides it a perfect camouflage upon which it relies on to ambush preys and to escape from the attention of predators. It has one of the fastest strikes of all snakes. Its cytotoxic venom causes cell damages and destroys tissue. The puff adder is probably one of the most toxic viper.
