Sawfish, distributed in the world's tropical and subtropical shallow waters, benthic, often in and out of harbors, estuaries, sometimes can be traced up the river quite a long distance head, long and flattened, elongated snout, much like sawsharks in the shape of a sword, flanked by strong teeth.
The largest body length can reach 7 meters, but the kiss saw, which occupies 1/3 of the total length of the body, is also very popular.
The kiss saw is used for feeding activities, or to discover underlying organisms, or to swing in schools of fish, kill or injure schools of fish.
Sawfish use giant "saws" like rakes to sift through the sand underwater in search of food.
They are ruthless predators, capable of cutting the bodies of their prey in half in water, just like human swordsmen.

The current decline in the population of wild sawfish has something to do with their "big saws", as fishermen can easily tangle their nets around large saws when they hunt, making it difficult for them to escape.
Sawfish can be up to about 7 meters long. Due to overfishing and hunting practices, the U.S. government listed sawfish as endangered as early as 2003.
