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

Treatment of snakes

I am not surprised that a snake coils itself around the bowl and stick on symbols of healing. The reason is that its venom is worth more than gold.

In the legends of Ancient China, a huge serpent – dragon – founder of the first emperors, that is absolutely God’s creation. The first humans, according to African legend, could, like snakes, change old skin for new and live forever. Snakes used for medicinal purposes in Ancient Egypt and in Ancient Greece.

If we move on from fairy tales to science zootechnology . this is the “great and powerful” poison (although it is not yet fully understood by chemists), consists of proteins, enzymes and substances that affect the muscles, bones, nervous system, cardiac function, and increased movement of leukocytes.

Cobra venom relieves pain and spasms, acting better than morphine, but without causing addiction.

The venom of the Indian Viper and Viper instantly swerve the blood, even in hemophilia.

And the venom of the Malaysian vipers, by contrast, is on three weeks, paralysing the process of blood clotting . what can help in the treatment of thrombosis.

The largest snake is the king Cobra, the most poisonous Continue reading
