Largetooth sawfish

The largetooth sawfish (Pristis pristis, syn. P. microdon and P. perotteti) is a species of sawfish, family Pristidae. It is found worldwide in tropical and subtropical coastal regions, but also enters freshwater. It has declined drastically and is considered critically endangered.[1][2][3]

A range of English names have been used for the species, or populations now part of the species, including common sawfish (despite it being far from common today),[2] wide sawfish,[4] freshwater sawfish, river sawfish (less frequently, other sawfish species also occur in freshwater and rivers), Leichhardt's sawfish (after explorer and naturalist Ludwig Leichhardt) and northern sawfish.[5]
