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

A poisonous snake leaves the skin with a trace in the form of two large, round wounds where the poison is injected, between which are two rows of small dots are the traces of small teeth. Unlike the wounds left by a venomous snake, markings bites of non-poisonous snakes (the snake, the boa) look like four rows of very fine dots.

All snake venoms mechanism of action are divided into 2 groups:

1) poisons acting on the blood (the pit Viper, steppe Viper, Viper) — there is severe pain, the affected area of the body turns red, develops swelling, increased or decreased temperature may be a fever, in the urine, the feces appears blood, the patient suffers from vomiting.

During the day on a sting place arises crimson spots, sometimes bubbles. In severe cases there are convulsions, paralysis of the limbs, involuntary discharge of feces and urine, comes death from respiratory arrest. The severity of damage depends on the area of the bite, the amount of poison received into the blood, the age of the patient and the depth of the wound. The worse defeat of Vienna, less dangerous bite soft parts of the body. Poisoning by the bite of a child is even stronger than that of an adult. Deep bites are more dangerous surface.

After snake bite, first of all, you should remove the poison from the wound for what it is necessary to wash and suck or squeeze the venom. When exhaustion is no threat, get poisoned, even if it is accidentally Continue reading
