The type of tooth that a shark has depends on its diet and feeding habits. In some formations, shark's teeth are a common fossil. These fossils can be analyzed for information on shark evolution and biology; they are often the only title: Shark tooth text: have ranged widely in their adaptations. Their teeth reflect this, ranging widely in form and function. There are a number of common types of shark teeth, that vary according to the diet of the shark. Examples include dense flattened teeth for crushing; long needle-like teeth for gripping; pointed lower teeth for gripping combined with serrated, triangular upper teeth cutting, and teeth that are tiny, greatly reduced, and non-functional. Dense flattened teeth are used to crush prey like bivalves and crustaceans. These Sharks include nurse sharks and angel sharks.

The bull shark is known for its aggressive nature, and presence in warm, shallow brackish and freshwater systems including estuaries and rivers. Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, about 700 miles (1100 km) from the ocean. title: Bull shark text: in the rivers and estuaries of Northern Australia, and a Nile crocodile was reported as consuming a bull shark in South Africa.
