Sawfish
Sawfish are mostly found in relatively shallow waters, typically at depths less than , and occasionally less than . Young prefer very shallow places and are often found in water only deep. Sawfish can occur offshore, but are rare deeper than . An unidentified sawfish (either a largetooth or smalltooth sawfish) was captured off Central America at a depth in excess of .
Sawfish
"Anoxypristis" contains a single living species that historically was included in "Pristis", but the two genera are morphologically and genetically highly distinct. Today "Pristis" contains four living, valid species divided into two species groups. Three species are in the smalltooth group, and there is only a single in the largetooth group. Three poorly defined species were formerly recognized in the largetooth group, but in 2013 it was shown that "P. pristis", "P. microdon" and "P. perotteti" do not differ in morphology or genetics. As a consequence, recent authorities treat "P. microdon" and "P. perotteti" as junior synonyms of "P. pristis".
