Feared by most, loved by some and hunted by many, sharks are one of the most mysterious groups of creatures roaming the Earth today. Defined as a fish with a full cartilaginous skeleton and a sleek, streamlined body, a shark can range in size from the two foot pygmy shark, to the colossal 50-foot whale shark.There are more than 250 different species of sharks currently identified, making it one of the most diverse animal genera on the planet.

There are a small number of shark species that do thrive in fresh water, and certain sharks have been known to venture from their saltwater homes to major freshwater lakes and rivers.Most members
