Sharks are some of the most amazing creatures on earth. They have evolved into a huge variety of shapes and sizes: From the tiny dogfish to the gigantic megamouth and whale shark species. Though most types are carnivores, many of them do not eat people unless provoked or the person is mistaken for a natural prey such as a seal, sea lion, or tuna fish. The total number of species is unknown. However, currently, there are close to four hundred classified kinds. Unfortunately, overfishing and nets are substantially dwindling the number of species. Furthermore, as many as 70 million to 100 million sharks are caught or slaughtered annually in comparison to a few dozen injuries and deaths caused by sharks. Nevertheless, as we continue to explore the deeper depths of the oceans and seas, hopefully, we will discover further species. Moreover, using sophisticated conservation techniques and stringent rules against overfishing these vitally important predators, we can keep these genera of fish going for generations yet to come.
