Fun-filled facts about the coolest

Types of Sharks
Well-known
sharks
There are about 440 species
of sharks in the world
No Bones!Fact#1
Sharks do not have a single bone in their bodies.
Instead they have a skeleton made up of cartilage.
Cartilage is a type of tough, flexible tissue
present in the human nose and ears.
Super Hearing
Sharks can hear a fish thrashing in the water from as far
as 500 metres away!
Some scientists think hearing is typically the
first sense sharks use in detecting prey.
Fact#2
Deadly Predators
Great Whites are the deadliest of all sharks, and responsible
for the largest number of recorded shark attacks on humans.
They can swim through water at an amazing
30 km/h!
Fact#3
A Painful Date
Male sharks find mates by biting female sharks. That is why many
species of female sharks have comparatively thicker skin.
Other animals which bite potential partners
are cats and turtles.
Fact#4
Just Keep Swimming
Some sharks remain on the move for their entire lives!
If the shark stops moving, it will suffocate and die.
Swimming forces water over their gills,
delivering oxygen to the blood stream.
Fact#5
I Smell Blood
A shark would be able to smell a single drop of blood
in an Olympic-sized pool!
Sharks have a very keen sense of smell
which they use for hunting.
Fact#6
Troublesome Babies
The first tiger shark pup to hatch inside its mother’s womb
devours its unborn siblings until only two pups remain,
one on each side of the womb.
Hammerhead sharks are born with soft heads
so they won’t jam their mothers’ birth canals.
Fact#7
Razor Sharp Teeth
The average shark has 40-45 razor-sharp teeth and can
have up to seven rows of replacement teeth.
Sharks lose a lot of teeth and grow them back quickly.
They often go through more than twenty thousand
teeth in a lifetime!
Fact#8
Special Attention Required
Humans kill about 30 million sharks per year trying to make
beaches safer or fishing.
On the other hand, only around 30 people die due to
shark attacks each year.
See the difference?
Alert!
Consequences?
Many species of sharks are nearing extinction. This will
cause an overall imbalance in the ecosystem.
Sharks inhabited the earth 200 million
years before dinosaurs appeared!
Let’s try to conserve them, please?
