Shark Species: An IntroductionThere are over 500 species of sharks. More species are identified each year because of new discoveries and also because DNA testing is enabling more finite identification of species. We have attempted to provide a broad overview of the species and how they are organized. We think you'll be amazed at how varied the world of sharks really is. Sharks are in TroubleSharks face the threat of extinction for a few reasons: the high demand for shark fins, unintended catch called 'bycatch' and man's fear and ignorance. In this section, we examine these threats to sharks. Shark MythsOne of the more interesting aspects of sharks is how they seem to have attracted strong beliefs and emotions in the minds and hearts of people everywhere. Much of what people 'know' about sharks is in fact false, driven by media, literature, fokelore, and ignorance. In this area, we explore some of those myths and try to supplant them with useful information. Shark Biology & BehaviorWhat makes sharks different from other fish? What is the connection between evolution, reproduction, and being at the top of the food chain? What is the range of behavior for sharks? This section, which is still in development, will include the answers to these questions.
