Species of sawfish Sharks:
Origin
The Sawfish shark is also known as the"carpenter shark". It is actually a species of shark. It is popular because of the extension that has it in front, the "saw". Some species can reach lengths of 7m.
The whole family of fishes is little known and very little studied. It is part of the family Pestidae and the order Pestiformes. The word comes from the Greek language and Means "saw".
The sawfish is widespread in tropical and subtropical waters of the Atlantic and Indo-Pacific oceans, being a dangerous target for any predator: it has 12 to 30 pairs of very sharp teeth.
It can be found in coastal areas as well as larger rivers, in cloudy or clear waters.
It can be found in other languages or literature under the names: the Bahamas sawshark, Pristiophorus schroederi
Shark feed saw
As you may well suspect the Daily Meal is made up mostly of fish. But besides fish, they also eat shellfish and other marine animals with or without a shell.
It can eat crustaceans with the help of the "saw" that helps it to break the carapace and other bone plates of the prey. Being a nocturnal animal uses the element of surprise.
If he sleeps during the day, at night he travels impressive distances in search of food.
Appearance shark saw
The Sawfish (Pristis) has an elongated trunk, flattened in front and a long snout and mouth in the shape of a saw blade, toothed on two sides.
They can reach up to 9 m in length, of which only the snout can be 2 m long and up to 30 cm wide. It is used to kill or dig. The fish uses its snout, quickly maneuvering it back and forth through a Bank of fish, that it chops many of them, after which it returns to quietly eat the mutilated victims.
To obtain its food it is helped not only by its multifunctional snout but also by short and flat teeth, with which it crushes the shells of crustaceans and mollusks.
It is a nocturnal fish that usually rests during the day to be in maximum shape when hunting. Despite his frightening appearance he does not attack people unless they are provoked or scared.

Since June 2007, the trade in fish saw has been banned. Only certain aquariums that prove able to meet certain conditions are allowed to purchase and hold such fish.
Breeding saw Shark
Being a little studied fish, very little is known about its breeding habits. They reach sexual maturity around the age of 10, when they are 3.5 – 4m long.
They are estimated to mate every two years. The female gives birth oviviparous, that is, gives birth to live fish, which are covered with thin membranes.
Membranes protect them during childbirth and help them get used to water gradually. They fall out or disintegrate shortly after birth.
