The smartest Dolphin in the world
Dolphins are recognized as the most intelligent animals on the planet after humans. First, they attracted the attention of scientists by the size of the brain, which sometimes weighs more than the adult brain. And then it turned out that the dolphins are well trained and have analytical skills, can show compassion and fun; they can even deceive for their own benefit. Not every Dolphin is equally talented, but among them are especially distinguished. Meet the bottlenose Dolphin, the most intelligent Dolphin, who is a big Dolphin and bottlenose Dolphin.
Appearance and behavior
The order Cetacea is divided into four major subspecies of dolphins, depending on place of residence: the black sea, the Atlantic (aka — normal), Indian and Pacific (far Eastern). To spot bottlenose dolphins chose warm water into temperate latitudes. Most of the time they spend near the shore, at shallow depths, but may come out into the open ocean.
These dolphins, like people, are social creatures, they live in groups of 15-30 individuals together on the principle of kinship. A small group, in turn, joined together. The number of the received super group reaches hundreds, sometimes even thousands of units.
The appearance of bottlenose dolphins
To recognize the bottlenose Dolphin can be short, clearly defined face with a prominent forehead and a moderately well-developed beak. A Dolphin breathes through special holes on the muzzle. Body length up to 4 meters, weight handsome from 200 to 400 kg, and males are longer and larger than females. The most common color of body dark brown on back and light grey on the belly, but the colors and transitions can vary and the back and belly are the same color.
Nature has endowed the bottlenose Dolphin is not only smart, but a good physique. Their neck is more flexible than the other members of the delphinidae family, and body shape and location of the fins reduces the resistance of the water. Fins broad at the base and tapering upward, located on the back and chest. Thanks to this set of characteristics the animal is able to accelerate to 40 km/h. But for a long time to swim at this rate Dolphin will not be so clever saves manpower and moved somewhere quieter, with an average speed of 10 km/h and acceleration are used only for sprints. Interesting fact: a Dolphin is able to swim to the surface for some air reflex even during sleep. And in the waking state it can jump to a height of five meters above the water.
Bottlenose dolphins live in groups, however, the issue of food every man for himself. To feed, they alone descend to a depth of one hundred meters; one session of dip lasts five minutes. Although it is not the maximum possible values, this mammal is able to stay under water for 15 minutes at a depth of 300 metres.
Hunting of bottlenose dolphins
But the most interesting thing, how exactly is hunting a bottlenose Dolphin. Water visibility is weak, so that the orientation is not used to seeing, and hearing. The sounds emitted by the bottlenose Dolphin, for the person sound like little squeaks and clicks, while the Dolphin ear discerns the subtle nuances, making your ears a main source of vital information. Bottlenose dolphins, like other dolphins, for the production of food using echolocation, that is, give a special high-frequency clicks. Published the sound reaches the object, is reflected and the echo returns to the source. Analysis of the obtained display gives the Dolphin information about the environment and location of live objects — shrimps, eels, squid and fish.
Communication of bottlenose dolphins
Bottlenose dolphins are spoken aloud with the purpose of communication among themselves, hunting, care for offspring and intimidate enemies. The range of possible sounds is striking: they snap, clap, whistle, chirp, buzz, squeak, scream, shout, smack and even croaking, barking and meowing, and even make sounds that the human ear can not recognize. It is believed that bottlenose dolphins can call each other by name, assigning a unique whistle to each individual. And different groups of dolphins may be even different dialects. Such a wealth of possibilities, the dolphins are required complex devices your sound device. But that’s not all methods of communication. Like humans, these creatures use body language adopt different postures, swim different styles, gesticulating tail and fins.
Caring for offspring
The threshold of entry into adult life is 5 years for females and 10 males. Dolphins come in contact with a partner not only for reproduction but also just for fun, bellies clinging to each other. In the case of fertilization, the female bears a calf a year. The twins rarely happens, usually it’s one kid. By the standards of a newborn bottlenose Dolphin small: length 150 cm, weighing 30 kg. six months the Mother feeds her, and then another year brings him solid food.

In their natural habitat bottlenose dolphins live 50 years. During this time they produce offspring about once every three years. While in captivity dolphins live twice as less and procreation rarely do.
Bottlenose Dolphin in the military
Man was able to adapt the intelligence and analytical abilities of dolphins for their own purposes. In the mid-twentieth century, the United States and the Soviet Union trained apalikov to catch swimmers who are trying to attach to the side of the ships, the mines and disarm them. These animals helped to do the work, and even performed underwater photography with the help of specially designed apparatus. Ability apalikov truly astonishing.

In our days, the bottlenose Dolphin is the most studied man, the representative of the dolphins, including due to the ease of domestication, it is precisely this kind of fun to interact with the person. Friendly Dolphin comes to the aid of drowning, rescues them from a shark and helps to swim to shore. And the man pays for good, and ingratitude closes the poor fellows in aquariums, making them the toy in dolphinariums, kill for meat and just for fun. Fortunately, today there are large shifts in this issue: many countries have already banned the hunting of dolphins.
