How does she feel?
One of the non-venomous snakes is already. Anyone who has ever watched his hunt, knows that he is an excellent hunter. For the success of this event, the snake can not do without the senses, which they have their own characteristics. Let's see what it feels like.
Types of snakes
There are three types of snakes live in Russia:
And even ordinary snakes can be identified up to 10 species. Between themselves, they differ in size and color. The largest individuals are found in Transcaucasia, their length can reach 1, 8 m. Already lives throughout Europe and even in North Africa. He is a real predator. The main part of his diet is various fish and amphibians, less often he manages to catch small mammals and invertebrates.
In winter, the snake hibernates. Its duration in the north of its range is as much as 8, 5 months, in Central Europe - up to 5, 5, and in the Mediterranean - only 3. Immediately after awakening, it starts shedding. And then in their life begins a crucial period of mating. Snakes come together in tangles of several individuals.Usually in such groups there are 5-10 males and only 1-2 females.
Two months after mating, the female searches for wet places: wet moss, rotten stumps, manure, rotten leaves, where she lays eggs. Depending on the habitat, the incubation of eggs can last from 23 to 61 days. The number of eggs in the clutch is different - from 5 to 36. Although naturalists met record clutches with 50 eggs. The second laying of the female makes in the second half of summer - early autumn.
Of all the senses, snakes have the best developed sense of smell, that is, the scent. They are able to feel even the most insignificant traces of various substances. In this they are helped by their forked tongue. You, probably, noticed that during movement all the time it thrusts out. In a trembling tongue, the serpent perceives everything around. When it closes the mouth, the tip of the forked tongue is pressed against two small pits located in the sky. This special body is called the "Jacobson organ". It consists of a cluster of cells with a huge number of receptors. These receptors are able to recognize the chemical composition of air, food, etc. By vibrating the tongue, it captures microscopic quantities of smelling substances from the air and analyzes them with the help of the Jacobson's organ. It replaces the organs of taste and smell.
All snakes, including snakes, could be called deaf. After all, they have no auditory holes or eardrums. Indeed, they do not perceive the sounds transmitted through the air. But snakes are able to very subtly sense vibrations coming through the soil. In this they are helped by receptors located on the tummy. Therefore, it is impossible to frighten the snake with screams, but it will most likely respond to the trampling by escaping.
The organs of vision in snakes are poorly developed. Therefore, vision does not play a special role for them. There is an opinion that the serpent's sight has a hypnotic property that can disorient the victim. In fact, this fact is not confirmed by science. The impression that the snake stares intently arises from the fact that it does not have eyelids. Therefore, she looks at the world without blinking, which creates the illusion of hypnosis. Protect your eyes with a thin film. Above the eyes of the snakes are protective shields, which give the snake's face a vicious expression.
