Froese, Rainer, and Daniel Pauly, eds.  Some waters where sawfish live are very murky, limiting the possibility of hunting by sight.  As traditional medicine (especially Chinese medicine, but also known from Mexico, Brazil, Kenya, Eritrea, Yemen, Iran, India and Bangladesh) sawfish parts, oil or powder have been claimed to work against respiratory ailments, eye problems, rheumatism, pain, inflammation, scabies, skin ulcers, diarrhea and stomach problems, but there is no evidence supporting any of these uses. , The pregnancy lasts several months. Monster sawfish of 15 foot Sawfish live in all tropiacal oceans and can maily found over sandy bottom. There has been debate about using water from the river for agriculture and to grow fodder crops for cattle in the region.  In captivity they have been seen using their saws during fights over hierarchy or food.  In contrast, several additional extinct genera are occasionally listed, including Dalpiazia, Onchopristis, Oxypristis, and Mesopristis, but recent authorities generally include the first two in the family Sclerorhynchidae and the last two are synonyms of Anoxypristis. The population rapidly crashed during the 1970s when tens of thousands were caught. , Since 2007, all sawfish species have been listed on CITES Appendix I, which prohibits international trade in them and their parts. , In Asia, sawfish are a powerful symbol in many cultures.  Sawfish served as the emblem of the German U-96 submarine, known for its portrayal in Das Boot, and was later the symbol of the 9th U-boat Flotilla.  The position of the first dorsal fin compared to the pelvic fins varies and is a useful feature for separating some of the species. Since this fish was caught in a net it won’t touch that record but the fact that it’s 50-pounds heavier makes this easily the largest alligator gar on record.  In an attempt of lowering this, a guide to sawfish release has been published.  It only survives for certain in six countries, and it is possible that the only remaining viable population is in the United States. There are five species of sawfishes worldwide, but in Florida …  Old stories of sawfish attacking large prey such as whales and dolphins by cutting out pieces of flesh are now considered to be myths and not factual. All fish must be caught per IGFA rules.  They have small eyes and behind each is a spiracle, which is used to draw water past the gills. For example, among the four species only two (narrow and largetooth sawfish) certainly survive in South Asia, and only two (narrow and green sawfish) certainly survive in Southeast Asia. Asian shamans use sawfish rostrums for exorcisms and in other ceremonies to repel demons and disease. , Sawsharks are typically found much deeper, often at depths in excess of 200 m (660 ft), and when shallower mostly in colder subtropical or temperate waters than sawfish. 'saw, sawyer'. In most regions the major population decline in sawfish started in the 1960s–1980s.  The saws are used in ceremonies and as curiosities. , Sharks and Rays Australia (SARA) are conducting a citizen science investigation to understand the sawfish's historical habitats.  Sawfish have been listed by CITES since 2007, restricting international trade in them and their parts. Largetooth sawfish ( Pristis perotteti ). All sawfish artwork ships within 48 hours and includes a 30-day money-back guarantee. The German World War II Kampfabzeichen der Kleinkampfverbände (Battle Badge of Small Combat Units) depicted a sawfish. There are proverbs with sawfish in the African language Duala.  Utilizing their saw as an extended sensing device, sawfish are able to "view" their entire surroundings by maintaining a position low to the seafloor. They can certainly all reach about 6 m (20 ft) in total length and there are reports of individuals larger than 7 m (23 ft), but these are often labeled with some uncertainty. , In captivity they are typically fed ad libitum or in set amounts that (per week) equal 1–4% of the total weight of the sawfish, but there are indications that captives grow considerably faster than their wild counterparts.  In 2003 an attempt of adding the largetooth sawfish to the Endangered Species Act was denied, in part because this species does not occur in the United States anymore (last confirmed US record in 1961). , The largetooth sawfish (originally Squalus pristis, now Pristis pristis) was among the species described by Carl Linnaeus in Systema Naturae in 1758, the starting point of modern zoological nomenclature, but sawfish were already known thousands of years earlier.  Those on the upperside allow sawfish to create an image of the three-dimensional area above it, even in waters of low visibility. The oldest known is the monotypic genus Peyeria where the remains are about 100 million years old from the Cenomanian age (Late Cretaceous), though it may represent a rhinid rather than a sawfish.  Individuals in public aquariums often function as "ambassadors" for sawfish and their conservation plight.  The final method involves pinning the prey against the seabed with the underside of the saw, in a manner similar to that seen in guitarfish. Examples of this can be found in Vicke Viking and Fighting Fantasy volume "Demons of the Deep". Encounters could not be substantiated in Belize and the five Guatemalan largetooth sawfish encounters resulted from a survey of Lake Izabal in the 1940s.  However, through genetic testing it has been shown that at least the smalltooth sawfish also can reproduce by parthenogenesis where no male is involved and the offspring are clones of their mother.  Also in Panama sawfish were recognized as containing powerful spirits that could protect humans against supernatural enemies.  The saw is highly streamlined and when swiped it causes very little water movement.  The rostral teeth are not teeth in the traditional sense, but heavily modified dermal denticles.  This strictly involved the largetooth sawfish where the Australian population remains relatively robust, and only living individuals "to appropriate and acceptable aquaria for primarily conservation purposes".  Illegal fishing continues and in many countries enforcement of fishing laws is lacking.

There are old reports (last in the late 1950s or shortly after) from the Mediterranean and these have typically been regarded as vagrants, but a review of records strongly suggests that this sea had a breeding population.  Outside Europe, sawfish are mentioned in old Persian texts, such as 13th century writings by Zakariya al-Qazwini.  The Kuna people on the Caribbean coast of Panama and Colombia considers sawfish as rescuers of drowning people and protectors against dangerous sea creatures.  There are no anal fins.  Pristis, the scientific name formalised for sawfish by Linnaeus in 1758, was also in use as a name even before his publication.  As far as known, sexual maturity is reached at an age of 7–12 years in Pristis and 2–3 years in Anoxypristis.  They are generally harmless to humans, but can inflict serious injuries with the saw when captured and defending themselves.  Young prefer very shallow places and are often found in water only 25 cm (10 in) deep. The current IGFA record is 55.2 kg (121 pounds, 11 ounces) and was set by fellow Luandan Hakan Ekberg in February of 1996.  In the narrow sawfish it has been estimated that the lifespan is about 9 years, and in the Pristis sawfish it has been estimated that it varies from about 30 to more than 50 years depending on the exact species. , Their small intestines contain an internal partition shaped like a corkscrew, called a spiral valve, which increases the surface area available for food absorption.  If protected their relatively low reproduction rates make these animals especially slow to recover from overfishing. , The most distinctive feature of sawfish is their saw-like rostrum with a row of whitish teeth (rostral teeth) on either side of it.  It is speculated that this may be in response to being unable to find a partner, allowing the females to reproduce anyway.  In some species, females on average have fewer teeth than males. In the smalltooth and green sawfish this equals a total length of 3.7–4.15 m (12.1–13.6 ft), in the largetooth sawfish at 2.8–3 m (9.2–9.8 ft), in the dwarf sawfish about 2.55–2.6 m (8.4–8.5 ft), and in the narrow sawfish at 2–2.25 m (6.6–7.4 ft).  Schools of mullets have been observed trying to escape sawfish.
