Remember from high school biology that organisms are divided into categories that get increasingly more specialized: kingdom, phylum, class, order, family, genus, and species. Sharks are part of the Animal kingdom and the Chordata phylum. They are members of the Chondrichthyes class of cartilaginous fishes. From there, subclasses of Elasmobranchii (including sharks, skates, and rays) and Holocephali (Chimaeras) branch off from one another. The order will vary by shark. Shark families then form (like the various hammerheads, for instance). The Latin names for sharks are based upon the genus (first word) and the species (second word). Additionally, for each species, there are common names. I prefer common names to avoid pretension and pronunciation complication, but knowledge of the Latin names can be useful. Lastly, the common names are sometimes used as an umbrella term for several distinct species.

The drawings on the top of the following page illustrate the common terminology we will need to talk about the parts of a shark tooth. These parts help us communicate with each other about the distinguishing characteristics that make shark teeth from individual species unique and identifiable. There are dozens of other distinctions experts use to describe shark dentition (tooth arrangement), but we will keep it simple and only use the terminology we really need.
