Black Sea: for inquisitive tourists
Traveler Vladimir Serkin talks about the difference between the fauna of the Black Sea and the Sea of Japan.
Dealing with issues related to the development of infrastructure in coastal regions, I visited the shores of the Black Sea and the Sea of Japan (Peter the Great Bay). Comparing them, first of all, I note that the Black Sea is less salty. There is a hypothesis according to which scientists believe that earlier the Black Sea (about 7000 years ago) was absolutely freshwater.
Another significant difference of the Black Sea is the absence of starfish and sea urchins, which we saw in numerous bays of Peter the Great Bay. There are two reasons for this fact:
1. Low salinity of water in the Black Sea;
2. The presence of hydrogen sulfide in the Black Sea at a depth below 150 m.
In general, the Black Sea is quite interesting and welcomes tourists with a much longer season, in contrast to the South of the Far East, where a comfortable swimming season lasts from July to September inclusive.
