For the vast majority of people hamster is a harmless and adorable creature that can harm except to himself.Its body length does not exceed 8-14 cm, which is 1/4 of the length of the tail. Weight is also small – only 50 – 70 g. compared to ordinary mouse hamster thicker and has a shorter tail. Coat – red-yellowish, the tip of the tail is white, its front legs in just the 4 fingers and on the back 5.
In the wild, depending on the area of habitation is found only 3 species of this rodent:
- South (Onychomys arenicola);
- North (Onychomys leucogaster);
- Hamster Mirna (Onychomys arenicola).
Kuznechikova hamster is a predator that prefers to eat not only insects, but also like-minded beings. For this characteristic of rodents and cannibalism, but only if other food in the area just left.
This unfeeling killer is largely nocturnal and feeds on grasshoppers, rodents, rats, and poisonous arthropods Scorpions.
Clever little rodent superior to their larger and stronger counterparts. Often prey kuznechikova hamster become the largest specimens of wild rats, and common field mouse.
His second name he received because unlike all the other creatures in the area of their habitat, he is able to fight even with such a formidable and dangerous opponent, as the wood Scorpion, whose venom is harmless to a hamster.
While in a fierce battle hamster gets a lot of strong punctures and bites from arthropod, but in doing so he endures any pain.
Skorpionov hamsters solitary, they don't hunt group and only rarely can get together to hunt a large group of Scorpions, or in the mating season to mate selection.
The breeding period kuznechikova hamsters coincides with the breeding period of all rodents in habitat. Unlike humans and some other mammals sexual intimacy hamsters no pleasure is solely a reproductive function.
In a litter is usually from 3 to 6-8 young that in the first days of life is particularly vulnerable to external threats, and need the help of parents and regular meals.
Newborn hamsters are very fast to train in captivity and find out how to attack the victim even without the guidance of parents is so advanced they have instincts.
The growth period continues for 3-6 weeks after which the hamsters gain independence and no longer need parents.
Aggressiveness is an inherited characteristic, it is typical for individuals who are nurtured by two parents. Such offspring often attacking other mice and more aggressive hunting any other prey than cubs reared alone, mother.
Gradually, growing up, Teens take better care of their housing. However skorpionov hamsters do not dig themselves nests, and away from other rodents, often killing them or driving if they manage to escape.
A howl in the night
Kuznechikova hamster howling at the bright moon, like a wolf that looks very terrifying, but if you don't watch him at the same time, you might think that this is just a song of some night bird.
They slightly raise the head, rising higher in the open, slightly open your mouth and emit a high frequency squeak in a very short period of time – only 1 – 3 seconds.
This howling is a form of communication and the interchanges between the various families in the area habitat.
The secrets of resistance to poisons
Kuznechikova hamsters have become the object of scrutiny by American scientists in 2013. The study's author, Ashley Rowe, had a number of interesting experiments, which had opened new, previously unknown properties and characteristics of this unique rodent.
In the laboratory of experimental hamsters was introduced to the rodent a lethal dose of poison wood Scorpion. For reasons of clarity, the poison was also introduced common laboratory rodents.
After 5 - 7 minutes, all laboratory mice were killed and kuznechikova rodents after a short recovery period and received from licking syringe wounds were full of energy and did not feel any discomfort and painful sensations.
In the next phase of research rodents were introduced, dose of the formalin – the strongest poison. Normal mice almost immediately began to writhe from pain, and hamsters don't blink and eye.
Scientists began to wonder – are these hamsters resistant to all poisons? Investigations were continued, and after a series of experiments and studying the physiology of these beings revealed some specific features of rodents.
Penetrated into the body of the hamster the poison mixed with blood, and almost immediately gets into the sodium channels of nerve cells, which he spreads throughout the body and sends signals to the brain about the strongest pain.
Rodents received a pain so strong that a special channel blocks the flow of sodium in the body, thereby transforming the strongest poison for the pain.
Constant exposure to poisons leads to the fact that there is a stable mutation of the membrane protein responsible for the transmission of pain sensations to the brain. Thus, the poison turns into invigorating tonic intravenously.
Such physiological manifestations similar to the symptoms of congenital insensitivity (anhydrose), which in rare cases occurs in people and is a form of genetic mutation.
Thus, kuznechikova hamster not only a first class assassin and night Stalker, which is completely insensitive to poisons and able to endure severe injuries without feeling a strong pain, but also a very intelligent animal, and breed well. Ability to survive and hunting instincts allow us to consider him an absolute predator, which has no equal in its category.
