Serrated edges on shark teeth typically belong to white sharks, tiger sharks, bull sharks and hammerhead sharks. White shark teeth look strongly triangular, while tiger shark teeth look notched and flattened. Bull shark teeth also possess a triangular appearance, but are stubbier. Hammerhead shark teeth look similar to white shark teeth, but have a narrower end towards the point. Unserrated, widely triangular teeth usually belong to the mako shark. Narrower, unserrated teeth typically belong to a lemon shark.
Long, narrow and sharply pointed teeth belong to sandtiger sharks. These teeth have a very recognizable appearance, which includes small cusplets at either end of the base.
The sixgill shark has uniquely shaped teeth that resemble a comb. It also has sharp, fang-like teeth in the upper part of its jaw.
