Apart from collecting prenatal pottery pieces (there seems to be no restriction against it), locals and tourists can enjoy a refreshing swim in the rolling, bluewaves of the Black Sea -- so called for the colour of its deep waters densely populated with algae.
They found that gravity waves "break" on the surfaces of planes, just like ocean waves breaking on the beach, causing much of the turbulence that occurs out of the blue in clear air.
The waves conceal whales, dolphins and sea turtles, and the western beaches are covered with armies of blue-backed soldier crabs that rear up on their hind legs and flee in panic at the approach of a human foot.
