Sawfish
The dwarf and largetooth sawfish are strictly warm-water species that generally live in waters that are and respectively. The green and smalltooth sawfish also occur in colder waters, in the latter down to , as illustrated by their (original) distributions that ranged further north and south of the strictly warm-water species. Sawfish are bottom-dwellers, but in captivity it has been noted that at least the largetooth and green sawfish readily take food from the water surface. Sawfish are mostly found in places with soft bottoms such as mud or sand, but may also occur over hard rocky bottoms or at coral reefs. They are often found in areas with seagrass or mangrove.
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".
