Amazing abilities of animals

In this article you will learn about the amazing abilities of some animals. Did you know that the chickens get rid of the sperm of roosters losers? Or as a person operates a purring cat? .. About these and other capabilities in the continuation of the theme.

Wood frogs can survive freezing

Amazing abilities of animals

The wood frog (Rana sylvatica), inhabiting Alaska freezes in winter to such an extent that it becomes like a piece of ice. While frozen, the frog does not breathe, her heart and blood circulation stops, she can not move. However, with the advent of spring frog "thaws" and return to normal life. It is highly unlikely that such ability could develop spontaneously by coincidence. In order to make the system function again the body of the frog, it is necessary to use an extremely complex genetic program.

Amazing abilities of animals

about 35-45% of the liquid winter in the body of the frog freezes. This extracellular ice, mainly found under the skin and between the muscles. With this frog becomes as hard as a piece of ice! Most of these frog-ledyshek survive the winter in Alaska in burrows on the ground level.

With the advent of spring tree frog ends its truly amazing transformation. Just a few hours a frozen frog's body come alive: restores normal breathing, heartbeat, blood circulation, as well as the work of the brain and all functional systems. The frog can move again, to jump and to mate.

Sea cucumbers can be converted from liquid to solid and vice versa

Amazing abilities of animals

Sea cucumbers (they Potbelly sea, they are also sea cucumbers) are a class of invertebrates such as echinoderms. They are somewhat similar to the larger worms - and in appearance and touch. (Have you ever groped a worm? Feel!) In general, as it may seem completely helpless creature.

Amazing abilities of animals

If the sea cucumber gets into a dangerous situation, he quickly acquires a kind of protection: its surface instantly hardens, becoming, as it were armor. As tell biologists, toughness provide multiple skin collagen fibers inside it.

Amazing abilities of animals

When the cucumber for some reason it becomes terrible, a special substance is produced in his body, which makes the softest tissue temporarily harden, and they are (in addition to being equipped with the said fiber) are very stringent. The result is a sea cucumber in the shell, and not flabby worm.

Some squids have built-in lights

Amazing abilities of animals

The colossal squid. Not to be confused with the more famous, but smaller in size the giant squid. The colossal squid is the largest invertebrate known to science, it also has one of the largest eyes in the animal kingdom.

Amazing abilities of animals

Each eye squid reaches a diameter of 30 cm, it can be more than a plate, and the lens of his eyes the size of an orange. These huge eyes allow the squid to see in dim light, which is very useful for an animal that spends most of his life hunting at depths greater than 2000 meters.

Amazing abilities of animals

It should be noted that until now was caught only the colossal squid - youth, adult same individual can grow up to 15 meters in length. These giants eye even more. Unlike giant squid, the squid has enormous stereopsis, and has an excellent ability to accurately estimate the distance.

Amazing abilities of animals

Even more amazing feature is that each eye has a built-in "spotlight", the body that can produce as much light as you need squid to see their prey in the dark.

Chickens get rid of losers cocks sperm

Amazing abilities of animals

Chickens choose the fathers to their offspring after copulation. If the leader is not a rooster, the hen does not resist copulation (likely to beak the head does not get) but after ejaculation "pours" of himself to his seed. If you ejaculate too little (and therefore, the male is weak and genetically inferior), the seed also goes in the trash.

Amazing abilities of animals

In the experiment with wild chickens (Gallus gallus domesticus) biologists measured quantity cock ejaculate. Wherein the measured and the volume which is left in the female cock, and one that female "poured" outwardly. It turned out that the chickens are selected sperm - they get rid of the semen socially low-ranking males. This means that if a cock - not the leader, the chicken does not resist mating (likely to beak the head does not get) but after ejaculation "pours" of himself to his seed.

Amazing abilities of animals

I've checked the volumes produced and thrown out of sperm, the researchers came to the conclusion that the hens with more intensity "cast" the seed of males, of losers - in the "trash" can take up to 80% of the ejaculate. From the ejaculate of cocks, hens get rid of leaders with less efforts. Another interesting fact is that the smaller the volume of ejaculate, the more the chicken gets rid of it. It turns out that the amount of seminal fluid serves as a marker of genetic usefulness cock. "If he has enough sperm, then he is weak, and leave him posterity is not worth" - something like this has to be chicken logic.

Amazing abilities of animals

"The release of semen can be an effective mechanism for increasing the chances of successful males leave their offspring," - says Dean Rebecca blog, describing the results of the study, published in the American Naturalist.

Cats purr to heal

Amazing abilities of animals

First, do not say nothing "hardy as a cat" - these flexible creation of a huge capacity for self-healing and treatment. For example, it has been observed that if someone in the cat's pride gets sick, the other members of the family go to there to give it energy or pick up bad. Cats perceive their owners as "big cats", so, in keeping with its nature, they too will have to treat. Scientists from the Institute for the Study of fauna in North Carolina came to the conclusion that the frequency of vibration, which urchat cats, accelerate cell regeneration.

A new method for the treatment of various diseases - koshkoterapiya - developed at the London Institute of therapeutic methods of influence. Closely the issue of science luminaries engaged after one night in the lab, where employees spent late experiment, the institute became their favorite - a cat of March. When it passed the low-frequency currents, unexpectedly zashkalilo all sensors. For fun, the researchers decided to measure the electromagnetic field of Martha. Imagine their surprise when it turned out that instead of a modern expensive generator, you can safely use a cat, because it can produce a much stronger field. After that experts have decided to continue the experiment. While the Institute developed a method of treatment of chronic inflammatory diseases with low frequency currents. Mindful of the sensor response to the cat, the researchers divided the patients-volunteers into two groups. One group they continued to be treated with the low frequency currents, and another group of people seated on the affected area cat. A month later, the scientists compared the results of the experiment: the sick, lechivshiesya by a cat, all recovered, and in the other group recovered only half of the patients.

Why is it a cat, currents of low frequency? And how do they affect the human body? Scientists say that low-frequency currents in cats produced thanks to its thin and delicate hair. When the animal moves, there is friction hairs each other, so that there is a strong electric field.
