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.

Regional assemblages of species of poisonous snakes in different geographical areas may vary depending on your location. In each location the major efforts must be made to be aware of the presence of toxic species, as they are not the dominant species and represent a danger to humans. In addition, they are much better known under local names or simplified compared to the more common and comparatively less dangerous individuals. In Panama, the special distribution received three main families of poisonous snakes, namely: alkoholowe vipers, coral snakes and sea snakes.
Only in the Western hemisphere of the Earth all the vipers are so-called pits, which represent a deepening from the outer side of the upper jaw, between the nose hole and eye, which indicates zoologist Harold Trapido, is sensitive to changes in the ambient temperature of the body. Thanks to its incredible sensitivity, this hole helps to locate and attack warm-blooded animals (of course, when the predator is close enough to potenitally victims). It is considered, among other things, that such amharinya bodies along the lower jaw perform the same functions and have common Boas (or devouring snakes). Even assuming that such a snake is removed and the language she blinded with blackened collodion, it will still be able to produce its fatal bite, aiming for an electric bulb, covered with Continue reading
