The current was carrying us along sheer walls, and she, mysterious and beautiful, gleamed in the distance.

Shark-Zebra

The shark disappeared into the depths, and I got a new hobby — a passion for cartilaginous fish. Have devoted a considerably long time, wrote some articles , even led a couple of sections in Wikipedia. Traveled to different corners of the planet to dive with them.
