Sharks: The story of a bookplate

Ten years ago, on the island of Sipadan in Malaysia, I took a picture of my first shark. It was almost certainly a shark-Zebra, Stegostoma fasciatum. The current was carrying us along sheer walls, and she, mysterious and beautiful, gleamed in the distance. My heart jumped to somewhere in the Adam’s Apple, I quickly raised the camera and took this blurry picture.

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.

Of all the sharks I liked Fox, or as she is known in English, thresher. She is like a shark-Zebra with long tail and harmless disposition. Graceful, smooth and swift. Without the aura of celebrity, without the reputation of a ruthless killer. So to speak, a humble toiler of the ocean depths.
