Sharks are amazing fish that have been around
since long before the dinosaurs existed. They
live in waters all over the world, in every
ocean, and even in some rivers and lakes.
Unlike bony fish, sharks have no bones their
skeleton is made of cartilage, which is a tough,
fibrous substance, not nearly as hard as bone.

There are many different species of sharks that
range in size from the size of a person's hand to
bigger than a bus. Fully-grown sharks range in
size from 7 inches long, up to 50 feet long. Most
sharks are intermediate in size, and are about
the same size as people, 5-7 feet long .

Sharks have a variety of body shapes. Most sharks
have streamlined, torpedo-shaped bodies that
glide easily through the water. Some
bottom-dwelling sharks (e.g. the angelshark) have
flattened bodies that allow them to hide in the
sand of the ocean bed. Some sharks have an
elongated body shape (e.g., cookiecutter sharks
and wobbegongs). Sawsharks have elongated snouts,
thresher sharks have a tremendously elongated
upper tail fin which they use to stun prey, and
hammerheads have extraordinarily wide heads. The
goblin shark has a large, pointed protuberance on
its head its purpose is unknown.

ANGELSHARK Angelsharks hide in sand and mud and
come out at night. They have a flat body and
sides that stick out like wings of angels.
COOKIECUTTER SHARK The cookiecutter shark has a
green glow from its belly. They are slow
swimmers. They have triangle teeth. Their eyes
are large and green in color. They take round
cookie cutter-like bites out of their food.

THRESHER SHARK They have very long tails and are
strong swimmers. They can jump out of the water.
Their teeth are small but very sharp. Its mouth
is behind its eyes.
HAMMER HEAD SHARK They have a thick white head
shaped like a hammer. They have a very good sense
of smell. They swim in warm waters.

GOBLIN SHARK We never see the goblin shark and
they are very slow swimmers. Their nose is
unusual because it is very long, flat and
pointed. Its jaw can open quickly to catch food.
As their teeth are lost or broken they are
replaced with new teeth that turn into place.
