The great white shark, also known as the white shark, white pointer, or simply great white, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. It is the only known surviving species of its genus Carcharodon.
Here are some amazing
great white shark facts
- Great whites give live birth from 2 to 12 pups,
and the gestation period can take up to a full year. When a great white shark is born, along with up
to a dozen siblings, it immediately swims away from its mother. Born on
the east and west coasts of North America, the south of Africa and
southwest Australia, baby sharks are on their own right from the start.
Their mother may see them only as prey.
- At birth a baby great white shark is already
about 5 feet (1.5 meters) long; as it grows it may reach a length up to
four times that. The pup (which is what a baby shark is called) will live
its life at the top of the ocean's food chain. But before it grows larger,
the pup must avoid predators bigger than it is—including other great white
sharks.
- Many baby sharks do not survive their first year.
Young great white sharks eat fish (including
other sharks) and rays.
As they grow, the sharks’ favorite prey becomes sea mammals,
especially sea
lions and seals.
- Sharks count on the element of surprise as they
hunt. When they see a seal at the surface of the water, sharks will often
position themselves underneath the seal. Using their tails as propellers,
they swim upward at a fast sprint, burst out of the water in a leap called
a breach, and fall back into the water with the seal in their mouths.
- The great
white shark is the world's largest known predatory fish. It has 300 teeth,
yet does not chew its food. Sharks rip their prey into mouth-sized pieces
which are swallowed whole. They can last a month or two without another
big meal. Sharks can smell a single drop of blood from up to a third of a
mile (0.53 kilometers) away.
- The shark’s heavy, torpedo-shaped body allows it
to cruise efficiently for long periods of time, and then suddenly switch
to high speed bursts in pursuit of prey—sometimes leaping out of the
water. It feeds on a broad spectrum of prey, from small fish, such as
halibut, to large seals and dolphins. Great whites (and other species of
shark) do not have eyelids and must roll back their eyes to protect them
when catching prey.
- The grey and white patterns on a great white shark
is to help them camouflage, from below they are hard to see against the
white light of the surface of the water, from above they are hard to see
against the deep blues of the ocean.
- Great whites are surprisingly docile for a
predatory animal and you can even swim along with them as long as you pose
no threat and do not panic, this does not mean you should swim with them
care free, if you move around to quickly and frantically this will kick in
their predatory instincts and cause them to attack thinking you are prey.
- Great whites do not live in just one area, they
are nomadic animals and can travel hundreds if not thousands of miles in
just one year.They can also live from 40 to 70 years and grow around 20
feet long or more. They cannot be kept in captivity because they cannot
get enough exercise in any size aquarium due to their nomadic nature and
will grow overweight and eventually die.
- Great whites are also preyed on by orcas, who use
the sharks tonic immobility against them to eat their kidneys and liver to
leave the rest to rot at the ocean floor.
- Great white sharks are decreasing in numbers and
are rare due to years of being hunted by man for fins and teeth, and often
as a trophy for sport fishing. The white shark is often caught as bycatch
by commercial fisheries and can also become entangled in meshes that
protect beaches.
- As large and powerful predators, great white
sharks play an important role at the top of the marine food chain. Despite
its fame and reputation, little is actually known about the great white
shark’s biology and behavior.
