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

And simple repair in this case is not enough.

Once there was an aquarium for fish the local waters, says head of the Department of amphibians and reptiles of the zoo Olga Kalinovskaya, and when in 1995 marking the centenary of the zoo, was transformed into the current terrarium. Now the zoo management plans to restore the aquarium, and over it to build the pavilion-a terrarium. It remains only to find the money to build.

Thus it happened that now to exhibit a collection of snakes for the zoo anywhere. New housing received only crocodiles, lizards and small amphibians in the premises of the recently renovated monkey house. The rest live in various closed the eyes of the visitors spaces.

In Kharkov zoo today is home to 20 snake species, only about 200 individuals creeping. All of them are tropical snakes that were bred in captivity.

Creeping the oldest inhabitant of the zoo — a female Continue reading
