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

For example, in Costa Rica due to the biting of the dies cacahuete bothrops at least 6 people. The snake’s venom causes the victim the destruction of red blood cells and blood vessels, the site of the bite swells, possible bleeding of the internal organs.
