An unidentified sawfish (either a largetooth or smalltooth sawfish) was captured off Central America at a depth in excess of 175 m (575 ft). [59] The dwarf and largetooth sawfish are strictly warm-water species that generally live in waters that are 25–32 °C (77–90 °F) and 24–32 °C (75–90 °F) respectively.
Pristis pristis (Linnaeus, 1758) — largetooth sawfish, common sawfish, freshwater sawfish, Leichhardt's sawfish; Pristis zijsron Bleeker, 1851 — longcomb sawfish, green sawfish; These are divided into two species groups. Most are considered a part of the smalltooth group, except P. pristis which is the sole member of the largetooth group. [9]
The smalltooth sawfish is found in tropical and subtropical parts of the Atlantic, including the Caribbean and Gulf of Mexico. Its original range was the smallest of the sawfish species, covering about 2,100,000 km 2 (810,000 sq mi). [5] In the west it once ranged from the United States to Uruguay and in the east from Senegal to Angola. [1]
