Snakes can starve while growing in length

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

India Horror stories: snakes, spiders and toads

In theory snakes in India are very even, a year from snake bites killed 50 thousand people. It is in a snake were the cause of my unwillingness to go to India, because it seemed to me that there are snakes everywhere: hiding under every stone and hanging on each branch.

Now, the first four-month trip to India not a single snake on the way I came across. It was the jungle and in various other habitats of snakes. Okay snake I have not met a loving person not to wear glasses. But the conversations with other travelers revealed the same fact: a snake in India is necessary to search for specially. Of course, some “lucky” and those who consciously sought out. But mostly snakes nobody saw.

The fact is that snakes don’t eat people, and catch mainly mice and rats, so the easiest way to come across a poisonous snake in the rice or barley field. It is therefore logical that one of those 50 thousand people that die every year from snakebites in India, almost all farmers, as the agricultural activity attracts creeping reptiles, but Indian doctors. which can inject anti-typhoid serum in the field about a remote village difficult to find, here and dying peasants. If the snake the snake will bite You and it will be given proper medical treatment, chances of survival are very high. The question is who will bite.

Assessment of the risk of being Continue reading
