Sharks have had remarkable evolutionary success. The first sharks lived approximately 400 million years ago, about 200 million years before the dinosaurs. They have survived the reign of the large reptiles by another 200 million years.
The International Shark Attack File, which contains data on shark attacks from around the world, reports fewer than 100 shark attacks per year, with about 10-15 deaths each year. In comparison, about 1,000 people die from attacks by crocodiles; 1,500 from tigers, lions, and leopards; and 60,000 from snakebites.

The great white shark has been implicated in more attacks than any other species. The tiger shark and bull shark are also known to be particularly dangerous.

Although it is true that there had been victims of shark attacks, there are a lot of misconceptions about these creatures.
