Pristis is a genus of sawfish of the family Pristidae.

Taxonomy[edit]

The genus Pristis contains from four to six species. Pristis has been divided into two groups, commonly referred to as smalltooths and largetooths.

  • Smalltooths: The Pristis pectinata species complex (P. clavata, P. pectinata and P. zijsron)
  • Largetooths: the Pristis pristis species complex (P. microdon, P. perotteti and P. pristis) is in need of in-depth taxonomic review. It is possible, for example, that P. microdon and P. perotteti may not be distinct species, but may rather be subspecies, or perhaps geographically distinct subpopulations of a single circumtropical species.
