Odontaspididae is a family of sharks commonly known as sand sharks or ragged-tooth sharks. While the common names of these species are frequently heard, there are several synonyms associated with the term 'odontaspididae.' The term 'Carcharias taurus' is one of the alternate names given to these sharks. Other synonyms for odontaspididae include the 'sand tiger shark' and 'grey nurse shark.' It is believed that odontaspididae is derived from the Greek word 'odous' meaning tooth, and 'aspis' meaning shield. These modern-day sharks have been in existence for millions of years and are distinguished by their sharp, menacing teeth and sleek bodies.
