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
Leave me alone, snake effervescent, or First aid for snake bite
In the den of the snake was modestly, but with a bite.
We wrote a lot about how to deal with tick bites, but never about what to do in case of snake bite, and this can be quite useful right now, in the summer, during vacations, Hiking in the woods and mountains, and even trips abroad to exotic countries, where so many not only wild monkeys, and poisonous creatures.
In Russia too there are a lot of poisonous snakes, the most dangerous of them: Cobra, Central Asian Viper, is less poisonous: the Viper and the Copperhead. Mostly vipers, which were generally of a peaceful disposition, in the form of a man trying to disappear immediately, and only bite for self-protection, as, however, and all the snakes. So be careful.
If you (or one of your companions) felt “a pinprick”, but don’t know what kind of snake, poisonous or non-poisonous, you have been bitten by, and in appearance are unable to determine or did not, inspect the wound. The figure shows the types of tracks that leave the snakes on the site of the bite. The first five – poisonous snakes (see the punctures of the fangs) and the sixth – non-poisonous snakes.
If you are unlucky Continue reading
