Saw sharks are among the most distinctive shark, with its snout that resembles a saw (called faces)
embedded with teeth. This curious adaptation is effective, as these sharks use it to remove muddy or
sandy bottom while searching for prey, which stunned by sudden movements of your saw. The saw
shark apart is the only shark eel shark has six gills, instead of the five or seven usually having another.
Some saw shark species are highly prized as a food source, especially in Japan. Saw sharks are an order
of sharks bearing long blade-like snouts edged with teeth, which they use to cut and disable their prey.
Most occur in waters from South Africa to Australia and Japan, at a depth of 40 meters and below, and
in 1960 the Bahamas saw shark was discovered in the deep waters of the northwestern Caribbean. Saw
Sharks have a pair of long barbells about halfway along the snout. They have two dorsal fins, but lack
anal fins, and go up to 170 centimeters long. Pliotrema genre has six gills and Pristiophorus usual five.
Sharks normally feed on fish, squid and crustaceans, depending on species. They cross the bottom, with
barbells and ampullae of Lorenzini on the saw to detect prey in mud or sand and then the victims
affected with the side to side strokes of the saw, crippling them. Although similar in appearance are
different from saw sharks saw fish. Sawfishes have a much larger maximum size, barbs missing, having
uniformly sized rather than alternating saw tooth and have gill slits on its lower surface instead of on the
side of the head.
Most distinctive feature is the tribune sawfish saw. The face is covered with electro pores that allow
sawfish to detect slight movements of prey hiding in the muddy sea floor. The gallery also serves as a
digging tool to unearth buried crustaceans. When suitable prey trying to swim past the springs normally
lethargic sawfish background and the bars on it with your saw. This generally stuns or impales the prey
sufficiently for the sawfish to devour. The fish also saw his face defend against intruders and predators
divers like sharks. The "teeth” protruding from the rostrum are not real teeth, but modified tooth-like
structures called denticles. The body and head of a sawfish are flat, and spend most of the time lying on
the ocean floor. Like rays, mouth and nose of a sawfish are in their flat bottom. The mouth is full of
small teeth, domed to eat small fish and crustaceans, sometimes swallows whole fish. Sawfish breathe
with two spiracles just behind the eyes that draw water into the gills. The skin is covered with small
dermal denticles that give the fish a rough texture. Sawfish are gray or brown overall, sawfish, appears
olive green.
