The family of snakes called vipers includes some of the most poisonous snakes in the world. These snakes live mostly in rain forests and wet places. They also dwell inside small caves in the mountains. Some examples of the snakes in this fearsome group are the water moccasin, rattlesnake and copperhead—all of which are found in the United States of America; the bushmaster and the fer de lance of South America, and the puff adder of Africa.
Vipers have thick bodies, short tails, and
triangular heads. The fangs in their upper jaws inject poison into their
victims’ bodies almost like a hypodermic needle. When the snakes bite, they contract the muscles around their poison sacs. These sacs are located behind the eyes. The poison squirts out through the hollow fangs. Almost half a teaspoon of poison is put into a victim at one time. Vipers mainly eat amphibians, small mammals, lizards and nestlings. The venom of the snake is not used for predators, meaning, they don’t fight with the venom, but they use it only for the prey. Their venom has more than a dozen toxic components. Fortunately, many of these snakes are small, so their bite is not fatal. An interesting fact is that these snakes can go without eating for a year. According to folklore, the touch of the tongue of the viper snake could heal a person.
The viper snake can have a lot of babies. During the month of August, the female snake gives birth to about 20 young ones in a litter. The eggs stay inside the mouth of the female viper. They are fed by the mother till they are old enough to take care of themselves. When the young are ready to come out, they are set free in the wild.
