Since the days of Ancient Greece, people have shown great interest in dolphins, because they considered them to be very intelligent beings. About dolphins, they made up a lot of myths and legends. With the advent of zoology, scientists have shown to dolphins no less interest than the ancient Greeks. In the process of studying dolphins, a lot of interesting facts about their life were collected. We want to share some of them with you.
Dolphins are social animals with a well developed intelligence. The brain of a dolphin is more human and has twice as many convolutions. In addition, dolphins can use both hemispheres alternately. For example, when the dolphin is closed to the left or right eye, this means that the left or right brain is asleep, and the second at this moment is active.
Vision in dolphins is poorly developed. But they have a unique hearing (echolocation), with the help of which dolphins perfectly orient themselves in space. To search for food, the bottlenose dolphins living near the shores of Australia use a sea sponge. They do this as follows: they put on a sponge on the sharp part of the muzzle and comb it to the bottom. This method they use, so as not to injure the small reefs or stones lying on the seabed.
The maximum speed at which a dolphin can swim reaches 50 km / h. Swim at such a speed may not all representatives of dolphin, but only dolphins of the blond.
Regeneration of skin in dolphins passes 8 times faster than in humans. This is not exacerbated by infectious infections, even if the water is swarming with bacteria. For example, a wound the size of a soccer ball in a dolphin heals in just a few weeks.
Dolphins breathe lungs, as well as humans, but instead of the nose, the organ that captures the air is the breather. Taking the air, the dolphin plunges into the water, holding the breath for 10 – 15 minutes.
Light dolphins process up to 80% of air, while human lungs can process only 17%.
Pain sensations in dolphins are dulled, because in their bodies, natural pain relievers are produced similar to morphine.
Dolphins have taste buds, with which they distinguish tastes: sweet, sour, bitter, salty.
Dolphins can communicate with sounds. In their “vocabulary” about 14,000 different audio signals.
Each dolphin has his own name, which he receives at birth. This fact was proved by scientists who recorded a sound signal at the birth of the baby, denoting the name. Subsequently, the same dolphin sailed to this sound.
Different kinds of dolphins eat different kinds of fish.
During the research it was found that dolphins recognize themselves in the mirror. This experiment confirms that they have self-consciousness.
Dolphins are very easy to train. If after such training the dolphin is released to freedom, he will necessarily return.
