And why vipers do not have to be completely destroyed?

The question of why vipers do not need to be fullyto destroy, has a fairly simple answer: because the development of science and technology does not yet allow mankind to create complex organisms, such as are all living beings on the planet, including snakes. Only one of the vertebrae in the skeleton of this animal is from 141 to 450, and the brain, extended along the body, allows the brain to move with lightning speed in the desired direction.

Snakes learn about the world throughthe amazing body of Jacobson, which is one of the most perfect chemical analyzers. Some species have thermal locators, which allow them to collect heat from a distance. Mankind invented a thermal imager only in the 20th century, and snakes use it for millions of years.

Experts know why vipers do not need to be completelydestroy. They are guided by the fact that these dangerous because of the venom of snakes are not really widespread. A concentrated amount of these reptiles can be observed in marshy areas, in places where there are many rodents, which are the main food of vipers. If, for example, there is no strong swampiness on your site, a heap of branches and debris, and also no mouse, then the probability of encountering a snake is reduced almost to zero. Gardeners recommend planting garlic, the smell of which is unpleasant for vipers, to have a cat, not to expel hedgehogs, which are the natural enemies of snakes. And outside the garden, snakes are natural bioregulators, which is why vipers do not have to be completely destroyed.

Like most living things, snakes avoidmeeting with a person. They even have a special coloration, which allows them to effectively disguise themselves. Therefore, bites are possible when a person attacks or manifests aggressiveness. Poison to the animal is needed for hunting, therefore, for food, the snake will not waste it. If a viper is seen before it is curled into a ring for a throw (it can rush to a distance of a meter), then you can simply bypass it, and everyone will go about their business. In this case, the snake itself can become a lunch for an owl, stork, ferret, fox or badger, which is another reason why vipers do not have to be completely destroyed.

On the territory of Russia is most commonan ordinary viper, which is a brown, black, greenish or bluish hue. With other species of this group, snakes can "meet" while traveling to other countries. For example, in Ceylon, in Thailand there is Russell's viper, which can be distinguished by a triangular head and a two-meter length. This animal is quite aggressive and fast, which creates the prerequisites for an immediate attack if it occurs.

The sand viper is found in sandy terrain,against which it is perfectly masked. The snake can be found in Iran, Algeria, Western Europe and Asia Minor. In Russia, it lives in the Caucasus. In its diet includes rodents, small birds, lizards. The full animal does not show aggression unless it is provoked. Often it is immobile in the sun for hours.
