Cornucopia

Cornucopia - as Cubans call the animal Caribbean sponge, which is shaped like a horn of plenty. All my life it sits in the same place, attach to underwater rocks or cliffs. It feeds on small animal single-celled organisms, which fall to it with sea water.

Horny substance of which was built the skeleton of the animal, according to their chemical composition similar to silk, contain large amounts of iodine. The height of the horn of plenty - more than a meter.

Besides this kind of Caribbean pink sponge found in the tropical coast of Central America and in the Mediterranean Sea.

Few people know that the sea sponge - the skeleton of the animal. This is a very archaic animal, almost unchanged since ancient times. At the beginning of the Paleozoic era, t. E. 520 million years ago, there were a sponge, like today.

The three-eyed lizard tuatara - the inhabitant of the desert islands of New Zealand - do not bother with device holes. She prefers a cozy nest of sea petrel.

Somehow lizard bird "negotiate" about communal living. According to a strictly defined "routine" they use nest in two shifts.

Puffin returns home for the night - just at a time when the lizard to hunt. But it happens that the bird bored hangers, and a lizard being driven away. It sets out no arguments, tuatra obediently moves to a new apartment - another petrels. This flexible "character" is produced from the hanger at once. After tuatry lizards live, by definition, scientists, five hundred years!

Few people know that there is a snake venom is ejected in a trickle to a distance of four meters! Three species of snakes, cobras lives in the tropical forests of Africa and South Asia.

The "shooting" cobras in his mouth is not a longitudinal slot and a small round hole. With a sharp reduction of toxic poison glands thin streams ejected from these holes. In the case of a miss cobra repeats "shot" several times.

Once on the mucous membrane of the eyes of the victim, the venom gets into the blood stream immediately. For small animals one shot is fatal. Larger animals from him blind.

The ancestor of all dogs.

The name "Husky" comes from «huskimos» - this is how the sailors British merchant ships were called the local Aboriginal people - Inuit. Paleontologists from the Royal Belgian University of Natural Sciences believe that the first dog is likely to resemble the Siberian husky is on, however, they were slightly larger, and there - a little less than 32 thousand years ago.

As an indicator of Wool

Eskimos in severe frosts like ironic repeat that tonight they will need three dogs - just propped himself on three sides "living heaters," they do not freeze. The unique structure of wool not only allows the "Siberians" to work at temperatures down to minus 60 degrees, but also frees them from the common to almost all the dogs smell. But scientists from the University of Alaska believe that the scalp Huskies could help in detecting mercury pollution of the environment. According to lead author of the study, chemist Kriya Dunlap, hair is a good indicator of pT4. Feeling guilty

Husky owners are well aware that it is better not to leave pets alone in a long time. In the absence of the company they easily find their entertainment: on the street - "hunt", producing food, such as in dumpsters at home - "restoring order", acting as a shredder. Ethologist Frans de Waal in his book "Kind" describes an experiment to verify the guilt Huskies. One of the dogs loved to do in the absence of a host of different milling market. The owner could not be reconciled with broken old newspapers, but when he discovered important documents destroyed or unread mail, the dog received a "reprimand" and seemed to feel a sense of guilt. This remorse was reflected in the eyes of the faithful dog, even in cases where the owner himself tore the newspapers and scatter them around the room. The researchers concluded that the animal, rather, does not feel a sense of guilt, and worries because of the behavior of his angry master, who follows her misconduct. And she did not seem to matter who it sovershil.uti, with the "you do not have to kill the animal."

Zebra - one of the few types of equine mammals, among which also includes horses and donkeys. 

Unmatched hooves are probably an adaptation to run fast on hard ground. Zebra belong to the genus of horses, but among all the members of this genus have a very unusual appearance.
But why zebras stripes? When zebra gather predators is difficult to choose one horse from the pack. Different species have different types of zebra stripes - from narrow to wide.
In fact, the farther to travel to the south of the African peninsula, the stronger will be different colors of zebras.

Recent studies have suggested that zebra stripes also help them attract less mosquitoes.

At the height of adult zebra can reach from 110 to 150 centimeters, if you do not take into account the head. Weight zebras can vary greatly depending on the subspecies - from 175 to 380 kilograms. Males are usually 10 percent heavier than females.

Grevy's zebra - the largest species of horse. In the wild, zebras live on average 20-30 years and in zoos - up to 40 years.

Basically zebras eat coarse grass, but can also have leaves that make up about 30 percent of their diet. Zebras - social animals that live in small flocks.

Zebras running slower than horses, their maximum speed - 55 kilometers per hour, but they are quite hardy, it helps them to successfully flee from predators. When persecution, zebras can run from side to side, which does not allow a predator to catch them. When serious danger rears zebra can with the power to kick or bite the offender.

If the food in a certain place is abundant, such as in the Ngorongoro Crater in Tanzania, zebras prefer to sedentary life. In the arid areas of the small group of zebras can be combined into larger and more together to migrate in search of food. Large flocks of zebras can travel a distance of 800 kilometers a year during migration.

Zebras are very dependent on the water, so they prefer not to go away from water bodies to which they should at least once a day to come to the watering hole. It is the duty of the oldest mare is leading the whole herd when they move from place to place, and ensure that the family was removed is not too far from the water.

Interesting facts about wolves

In fact, people are attacked by wolves is extremely rare, and even then, when people pose a direct threat. Like all predators, the wolf is forced to go on the hunt.
Wolves are intelligent animals and are easy to remember commands. So easy to become accustomed. An interesting fact is that each wolf own individual character: there are careful, others bold and fearless, others arrogant. Some notable in the pack and they are considered to be, others are quiet and modest.
On Earth, the wolves live a very long time. Human intervention in the environment wolf made its changes. Wolf has gradually turned into a dog and became his first assistant and protector. But that was a long time ago, several million years ago.
Wolves live in families, they religiously revere the "law of ranks". That is, according to him, each member ordered his place in the pack. The most powerful and clever run by a bunch, and all others must obey them.
The wolf family there are 6 of 15 animals. The strongest of them becomes the leader. Assistant becomes his loyal wolf. This pair of substantially and leads a flock. All matters relating to life-support pack resolves this pair. And so they all obeyed, the leader must be strong and bold.
Relationships in the pack

Between themselves, wolves, usually do not fight. But with animals from other flocks which have come on someone else's territory, fights often occur. Each pack has its territory to hunt, it is strictly guards its borders.
Wolves labeled it, thus showing who owns the territory. Anyone who invades their territory, will be severely punished. It happens that some - some weakling poisoned by his own countrymen. And when it gets hard, it leaves the flock. He becomes an outcast.
You do not like it? Sound familiar, does not it ?! You know the saying of the man - a lonely as a wolf? That's why he's gone from everyone as the rogue wolf, and lives alone. Over time, they can create a new pack, but for this he needs to meet a lone wolf.

The pack leader controls the males, the she-wolf of his girlfriend. To flock obeyed, the leader of the pack members growl, bite, chase them. And this happens in front of the wolves. Evil leaders look quite so others they obeyed.
Guilty animals spare the leaders, clinging to the belly of the earth. And sometimes fall on his back legs to the top. Thus, they show that they know who is boss.
An important role in communication between animals plays a tail. In the main it is raised high "pipe". In the middle of the hierarchy it is omitted, and at lower level in the wolf pack he is biased to the belly. But wolves love their leaders. This they did dedicate a ritual.
They pressed their ears and crawling with smoothed hair moving to the leader and his wolf, licking and gently biting them.
