Photos from open sources Dolphins, like some other marine animals, are known to communicate with each other using ultrasound. But if the water is strong “polluted” by various noises, say, from engine operation ship, how do the inhabitants of the seas in this case?
Having analyzed and studied this issue more thoroughly, researchers determined that in a “dirty” environment dolphins have to spend eighty percent of energy and oxygen more to communicate with each other, without which it is impossible in a pack even fishing. And if animals spend more energy on communication, then they have to consume significantly more fish in order to make up wasted resources.
According to biologists, “noisy water” is still in third place among all factors threatening the normal existence of dolphins at sea, however, we still do not know for certain how much we ourselves dolphins are sensitive to this pressure from the human civilization. Is this not the reason why in the last dolphins are increasingly being washed ashore mass suicide, or simply “going crazy” from the noise that standing in the water?

By the way, the need for additional food due to noise in the water – this is also a big problem for marine animals. They are so big part of the time they spend in search of fish, and if you need it now to extract almost twice as much, then dolphins begin to starve, which affects the size of the population. And even that can become cause of their ashore. Because dolphins are very smart, they they can just look for salvation on the shore or express their protest against the invasion of man in their calm marine life.
New research by scientists, writes The Journal of Experimental Biology, will help professionals and all those who engaged in the protection of marine animals, develop and find new ones methods for preserving the number of dolphins. However massive recent emissions of these animals practically all over the world, proves that such efforts are far not enough. Man needs to radically change his attitude towards the sea and all life in it.
