According to listening to the mouth to remember the names for decades, these 20 jaw falls prove that the dolphins are the coolest creatures of the ocean - and perhaps even all over the planet!
1 The skin of a dolphin regenerates every two hours.
The skin of the dolphin, which is smooth and rubbery, plays an important role in their movement underwater. In order to swim as effectively as possible, aBottlenose Dolphin's skin flakes and peels so that new skin cells replace old cells almost allof them Hours - nine times faster than humans. This helps ensure a smooth body surface to increase the ease of swimming under the sea.
2 They can talk to each other.
Scientists have discovered that the dolphins have a "spoken language spoken very developed", like that of humans, making a combination of legumes, clicks and whistles that allow them to communicate. A 2016 study, published inPhysical and mathematics, described how the language "presents all the design characteristics present in the human spoken language [which] indicates a high level of intelligence and conscience in the dolphins ... [T] Heir Language can be considered as a language spoken very developed. "
3 The dolphins have the longest memories of any animal.
To forgetelephant-Dolphins are animals with lasting memories. Research published in theActs of Royal Society B In 2013, he proved that remote giphone dolphins can remember the whistles of other dolphins they lived for two decades, even when they were separated from each other. While elephants and chimpanzees were both found to have an impressive reminder, they did not get closer to a period of memory of 20 years.
4 Dolphins recognize themselves in mirrors.
Usually when an animal looks in themirror They do not know what they see or think that reflection is another animal and act aggressively. Not as well as dolphins-that can recognize that it is not another animal look at them, but rather their own reflection. For a definitive study of 2001 at theNew York AquariumThe researchers have installed mirrors in the tank of a pair of gyld dolphins, marking each dolphin with temporary ink, that the dolphin then looked into the mirror. "Our results show that self-recognition can be based on a different neurological substrate from dolphins," concluded researchers.
5 The dolphins listen with their jawbones.
Scientists believe thatthe sound is worn Water in the inner ear of the dolphins through its lower jaw. The jaw is hollow (unlike land mammals) and contains a fat substance that connects to the ear. When a lower dolphin jaw is covered, it struggles to distinguish sounds, while covering its ears has no impact on its ability to hear.
6 Dolphins are conscious respirators.
Humans are unconsciousbreathable. We breathe and let out without realizing it, that we are asleep or awake or just quite unconscious. Dolphins, however, must make an active decision on each breath. AsBruce Hecker, director of breeding at the aquarium of South Carolina, saidAmerican scientist, a dolphin must be perfectly conscious that their blowing hole is on the surface, then deliberately makes the choice to inspire.
7 And they can inhale eight gallons of air in a second second.
A study published in theExperimental biology diary In 2015, analyzed the respiratory schemes of dolphins. The researchers found that they could inhale eight gallons of air in a second and expire 34 gallons per second-three times faster than humans, allowing them to replace as much as95% air in their lungs in a single breath.
8 The eyes of the dolphins move independently.
While the eyes of humans move in the same direction, coordinating with each other, the dolphins have a lot more room for maneuver - with each eyelocated laterally on the sides of their head and operate independently of each other. This means that they can have a much more expansive vision of what's going on around and even behind them while they swim through water filled with predators. But that's not all…
9 They literally sleep with an open eye.
According toConservation of whales and dolphins, the dolphins rest only half of their brain at some point. For a sleep period, they will rest their left brain; Then they will do the same with their right brain.
This means that the part of their brain can still open the blow hole while it is above the water to take air while the other part of the brain sleeps. You can actually tell what part of a dolphin brain is currently active because their opposite eye remains open, which allows it to swim directly and watch predators.
10 And they live on power naps.
Dolphins can not simply be conk for the night and get a solid eight hours ofpeaceful sleep Like us, humans, they are drowning if they tried it. (See: all active respiratory things.) Instead, the Dolphin research center in Florida saidMental floss They take electrical naps of 15 to 20 minutes throughout the day, allowing them to rest without risk of being underwater for too long.
11 Some can jump up to 15 feet!
Dolphins can get serious air. Researchers atDolphin wild foundationFor example, I reported that seeing dolphins skip to the wild up to 15 feet - with spinner dolphins, spotted and commerson dolphins tending to be the highest riders. The reason for this behavior? This requires less energy to jump than swim, because the air is less dense than water.

Unfortunately, a number of these species are listed asendangered or vulnerable, as the dolphin of the gang river, of which there are less than 2,000 people.
15 Dolphin babies were born the tail first.
To prevent drowning, a dolphin baby isBorn with his tail firstAnd the mother quickly breaks the umbilical cord avoiding quickly before turning a turn and quickly escutting his newborn to the surface so he can take a breath. In other words, the new mother does not get a lot of time to rest after birth. (Incidentally, when a dolphin nurse, she must hold her breath.)

18 Dolphins enjoy intimacy.
One of the rare animals in addition to human beings to enjoy sex are dolphins,Dara Orbach, a marine mammologist at Dalhousie University in Halifax, Canada, saidScience. They have been known to exercise preliminaries and many positions when copiling.
19 And they can live as long as humans.
Funny: The Orca Whale is a species of dolphin , not a whale. An even more fun fact: while the Orca average lives at about 50 years, it's not rare For them to reach 70 or 80 years. The funniest fact? a Orca named Granie lived until she was 105!
