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
Relatively little is known about the reproductive habits of the sawfish, but all species are ovoviviparous with the adults females giving birth to live young once a year or every second year. In general, males appear to reach sexual maturity at a slightly younger age and smaller size than females. As far as known, sexual maturity is reached at an age of 7–12 years in "Pristis" and 2–3 years in "Anoxypristis". In the smalltooth and green sawfish this equals a total length of , in the largetooth sawfish at , in the dwarf sawfish about , and in the narrow sawfish at . This means that the generation length is about 4.6 years in the narrow sawfish and 14.6–17.2 years in the remaining species.
