Introduction
Well a shark is one of the fiercest creatures in the ocean. All though you may think that all
sharks are deadly and dangerous you’re wrong the whale shark is actually a gentle giant. Sharks are
fierce predators of the
ocean that have been
alive since the time of
the dinosaurs. So
there you go here are
some more facts
about sharks.

Thresher
sharks are
subtropical sharks
that swim near the
surface. The only
shark alive today to
have six gills is the
six gilled shark.
A hammerhead shark
Great White Sharks
can grow up to 21 feet (6.1 meters) long that’s as long as 21 rulers Great white shark
put tip to tip! Cookie cutter sharks get there name from the marks
they leave that looks like the victim got a cookie cutter ripped out of him, her or it.
The nurse shark can pump water over its gills. Half the length of a thresher shark is its tail. No
thresher shark that we know of has ever attacked a human. Most short fin Mako sharks are found
(live) in tropical and warm temperate waters.

Nurse sharks mainly eat fish, crabs, shrimp, and lobsters. Great White sharks
are one of the deadliest sharks ever. Bull sharks are one of the few sharks that can
live in fresh water. Hammerhead sharks are mostly found in warm temperate
and shallow tropical waters.

was once hunted just
for the 250 gallons of
oil in its bladder.

Mysterious Megalodon
The largest shark that ever lived is called the
Megalodon. The Megalodons tooth is about two
times as big as a 6” paper. The Megolodons jaw is
about 10’ long. The Megalodon could have weighed
50 tons (45 metric tons) that’s as much as three full
grown rhinos!!

Scientists have found at least two Megalodons
on every continent except for Antarctica. One of the
Megalodons main prey is the sperm whale. The
Megalodons head is 20’ long. That’s as long as an

The Megalodon lived
2 to 17 million years
ago.

Megalodon means “mega tooth” which comes from the size of their tooth. Scientists think
that the Megalodons are extinct but from major tracking researchers have found a live Megalodon.
Megalodons like most sharks where Carnivores (meat eaters.). Megalodons were beastly and
deadly creatures.

What’s a Sharks Body Like?
A shark’s body is very unique. A shark’s heart has four chambers which are close to the gills.
All sharks have five different fins the cuadual fin, the pectoral fin, the first dorsal fin, second dorsal
fin, and the pelvic fin. Sharks have many different rows of teeth so if the first row wares out the
row behind it will take its place.
The first dorsal fin is located on the top of the shark and is aerodynamic which makes it so the
shark can gain more speed. The pectoral fin is located
on the side of the shark and is used to help steer the
shark. The cuadual fin is located on the end of the
shark’s tail and is used to gain speed. The second dorsal
fin is located on the tail and is used as a
weapon on the shark. The pelvic fin is

Sharks anatomy
A shark has no bones except for
the spine and the rib but the rest of the shark is cartilage. Sharks brain is about the size
of a person’s head or a dog’s head (depending on the size of the shark). Sharks heart is

located very close to the gills so they can get blood to the head fast. Sharks gills are what make a
shark breath because they are connected to the gills which have a filtering system that suck in the
oxygen and lets out the water back through the gills.

What is a Sharks Habitat?
Well as we all know a shark’s habitat is in the ocean BUT… a shark can live in
many different oceans for instance the Great White Shark can live from the
Pacific to the Atlantic Ocean. Lots of sharks like the black tip reef shark, the
coral shark, and the nursing shark all live in the coral reef. Sharks live all over
the world even by Greenland!! The most common places for sharks to live are
Pacific and Atlantic Ocean.
Coral reef
The coral reef is another one of the most common places for a shark to live.
About one quarter of species of sharks live in the coral reef. The reason why a
lot of species of shark live in the coral reef is because of all of the fish. The coral reef is home to
many different sharks like I said in the paragraph above but here are some more. The white tip reef
shark and the sand shark.
Fatal Facts
Sharks live in all
oceans except for
the Arctic Ocean.

Some sharks like the goblin shark lives at least 1,000 feet deep down. The six gilled shark lives
23,000 feet under the sea. Some other sharks like the goblin and six gilled shark. There you have it
some facts about a shark’s habitat.

Supreme Scales
Covering a sharks body are thousands of tooth
like scales. Sharks scales overlap each other. Dried
shark skin is called chagrin. Placoid scales make a
sharks skin rough. Sharks scales may seem flat but
they’re are all overlapped.
Sharks scales are very rough. Sharks scales are
mostly gray and white but the goblin sharks scales ore
Sharks scales
slightly green. Some shark scales are eventually worn
out and fall off. Sharks scales are rougher than sand paper.

Sharks scales are made out of the same thing as the inside of your nose (cartilage). Sharks
scales are so tiny that they look like plain gray skin on a shark. Sharks scales are basically natures
Kevlar.
Fatal Facts
Sharks scales were
once used as sand
paper.

It’s a Sharks Life
All sharks except for the Bamboo shark must move to live. Some
sharks that eat meat will swim up under their prey and jump up with
their prey in their mouth. Sharks mostly avoid sperm whales as a
predator. Shark must move even when sleeping.
The shark’s main prey, the seal
Fatal Facts
If a shark stops
moving it will die
Sharks must always be aware of
their surroundings because they never
know what predators might be lurking
around. Sharks eat around 578 pounds
of blubber (fat) every day. Sharks main
prey is seals. Some sharks will actually
attack baby sperm whales.
Sharks mostly eat the blubber from seals
not the skin. Sharks mostly don’t have to
avoid predators but they still have to watch
out. Sharks most feared predators are
