What scares sharks in the Black Sea, why they do not swim there
It is believed that sharks They don't. Therefore, local tourists have nothing to fear, because the probability of meeting with a formidable predator is minimal. Why do sharks avoid the waters of the Black Sea so much that no one sees them?
Sharks in the Black Sea: Why do sharks never swim in the Black Sea? If you look at the comments on social networks under this question, you can find many interesting answers. One writes that the Black Sea is too “black” for sharks to see. Another wit claims that Turks do not let sharks through the Bosphorus for free. The third joke is that in the Mediterranean, tourists taste better.
Of course, scientists offer their own options. One widely accepted explanation is that the water in the Black Sea is much colder than in the Mediterranean, so sharks are in no hurry to leave a more comfortable environment.
The next reason is that in the Bosphorus there is an intense movement of various vessels that create a lot of noise. Sharks don't like that. In addition, ships scare off potential prey, which sharks could eat.
Here, researchers also say that the Black Sea is relatively poor in terms of wildlife. Therefore, it is difficult for voracious sharks here to feed themselves and their offspring. Curiously, the Azov Sea is better with the stern, but it regularly freezes in winter.
Another reason to avoid the waters of the Black Sea is its lack of salinity. For example, the salinity of water in the Mediterranean Sea is 38 ppm, which is even slightly higher than the average salinity of the water of the world’s oceans (ranging from 33 to 36 ppm). But in the Black Sea, the salinity of water is only 18 ppm. A huge difference!
Finally, let’s talk about what many people call the main reason. The thing is, in the waters here. hydrogen sulfide. This is the uniqueness of the Black Sea, because of which sharks (and many other animals) can not survive here.
There are some species of sharks in the Black Sea. For example, there is a Black Sea catran - a marine cartilaginous fish from the family of catran sharks. There is also a cat shark. But this view of the Black Sea falls rather by chance, as a guest. Local conditions are not suitable for normal life and reproduction of cat sharks.
Scientists say that for centuries on the Black Sea beaches there was not a single recorded case of shark attacks on humans. At the same time, researchers are upset that sharks cannot fully take root in the Black Sea. In recent years, many populations of these predators are on the verge of survival. Therefore, their appearance in new locations would give hope for improving the situation.
