The usual fear of snakes peculiar to the majority of people caused by ignorance. Even a harmless snake is sometimes viewed with apprehension. However, there is no need to fear snakes if you have at least some idea about them and their habits, about how to distinguish poisonous snakes, about the simple measures to prevent bites and how to provide first aid in those rare cases where the bite took place.
The probability of being bitten by a poisonous snake is very small. Danger of death from snake bite is much less than the chances of dying in a car accident or from accidental discharge.
Forget about the exaggerated danger, which in the popular literature and various stories associated with snakes. Do not believe the rumors about the number, size and ferocity of the snakes that live in a particular area. The locals know all poisonous snakes, but also many harmless species of snakes can be represented as deadly. Statistics on the number of people bitten by poisonous snakes, unreliable. This is particularly true of deaf areas where dangerous snakes are numerous. Besides accidents almost always happen to those people who don’t wear shoes and therefore get a bite on the foot or ankle. So if you wear boots and pants, the danger Continue reading
Biologist Marshall Mackey (Marshall McCue ) from University of Arkansas (University of Arkansas ) undertook a study of the biological mechanism that enables some snakes to starve for up to two years.
For that, he spent 168 days observed 62 individuals of three snake species (distant relatives): Royal Python, white snake and Texas gramatnica.
Macku followed physiological, compositional and morphological changes of the snakes and found that snakes can reduce their metabolic rate by 72%! For this they use a special survival strategy in the absence of food, is not peculiar to any of vertebrates.
The rate at 72% is shocking, as “snakes and so consume little energy, and we still didn’t know how they manage to reduce energy consumption to such a low level”, ” says Marshall.
What’s even more amazing is the fact (also found by Makku) that snakes on loss from 9.3% to 24.4% of initial body weight continued to grow in length (especially increased size of the head – just like those snakes).
Day 168 to study rattlesnakes showed a record decline in the intensity of metabolism. He was only 28 per cent. Snakes reduced the metabolism to the bar in 55%. At the same time, the pythons, the maximum decrease in the intensity Continue reading
Enemies include snakes and humans. A poisonous snake never attacks. When meeting with a person she tries to crawl away to the shelter. The bites are the only means of protection of the disturbed snakes. However, a person encountering a venomous snake, mercilessly killing her.
Obvodnaya or draining certain areas, people indirectly harm the snakes living there, depriving them of a favorable condition. While fighting the rodents, it deprives them poor.
Sickness of snakes is poorly known. Some data are available regarding the parasite of the Viper and steppe Viper. The vipers registered 8 species of parasites: 3 — of flagellates, 2 ” tape 1 ” round worms, 1 — of acanthocephala, and 1 — mites (Markov and others 1966). The Central Asian Viper — 11 species of parasites, of which 2 are of the simplest type, 1 — to tapeworms, 5 ” round worms, 1 — the acanthocephalans and 2 — to ticks (Zinyakova and others 1966). In the Viper and the Viper obnaruzheno lung, upper respiratory tract and liver spot tubercles of tuberculosis. There have been cases of diseases of the mouth.
Venomous Continue reading
