Interesting facts about sharks

Our friend the shark has the obvious connection to almost every water sport enthusiast out there. A lot of us suffer from a phobia or fear of shark attack, not convinced? Who doesn't jump out the water instantly when they fall into the deeper water?

Perhaps it is indeed a matter of understanding and awareness. Most of us turn the channel or look away when there is a show or images of sharks because we just don't want the thought of getting bitten to pop into our heads.

Here are some real but interesting facts about these animals that might change your view in the slightest degree about them.

Shark facts

Here are some interesting shark facts that you might not know about

What are my chances of getting killed by a shark?

You have a chance of about 1 in 300 million, the reason why it seems so more common is because of the fact that it's so infrequent that when it does happen, it makes every headline in the world. Rare instances are absolutely loved by the media. Things that happen often are less likely to get reported.

You have a far greater chance of getting killed by lightning, coconuts or bees. If coconuts are more lethal than sharks, why aren't we more afraid of them? The answer is... "the idea of getting eaten alive".

Is the movie Jaws real?

Surprisingly, the movie is based on a real event that happened in 1916 where 4 people were fatally attacked by a killer shark in New Jersey, USA.

Sharks may cure cancer

Sharks hardly ever get cancer and scientists are trying to figure out why, if they do, we might be able to enjoy the same benefits. Also, according to recent studies, sharks are at greater risk of cancer today due water pollution.

How many types of sharks are there?

There are just over 440 known types of shark. It's likely that there are a few more species unknown us.

We all want shark teeth

A shark generally has about 45 teeth at a given time with several rows (up to 7) of replacement teeth. They grow back fast, real fast, in fact sharks can go through more than 30 000 teeth in a lifetime.

Sharks have no backbone

Sharks have no bones at all and their "skeletal" structure is made up entirely of cartilage, which is a little weird indeed.

Shark live is tough

The first tiger shark pup to hatch eats the other unborn sibling pups until only two pups are left.

Sharks hate men

90% of shark attack victims are men. Who knows why, but it seems they have some hidden agendas.

Shallow water attacks

Most attacks happen in shallow water, so our greater fear of deeper water is somewhat unfounded. Even though we feel safer in shallow water, the risk seems greater.

Sharks ought to be afraid of us

For every 1 human that is killed by a shark, we kill a few million in return, talk about race discrimination.

Fresh water

Bull sharks are able to swim up river into fresh water and readjust or regulate their bodies accordingly. They can swim thousands of kilometers up rivers. Perhaps there is a justified fear for sharks in your toilet.

Old bastards

Some sharks live long, the Whale shark can live up to 100 years and they're also the largest fish in the world. However, this poor sucker has to wait 30 years until they can produce baby sharks.

Shark attack vs shark deaths

While the number of shark attacks are small, the number of deaths by shark attacks are even smaller. Most of us assume that a shark attack means that someone has been killed, in fact most attacks don't result in death.

Are all sharks evil killers?

Only a few sharks of the hundreds of species are "potential attackers" that could harm us. There are actually only 3 sharks worth mentioning as potential threats. The Great white, Tiger shark and Bull shark. Which are responsible for the majority of attacks on people.

Not so deaf of dumb

Sharks have ears and have good hearing. They have inner ears that can pick up sounds from 250 meters away.

No rest for sharks, ever!

Some sharks will simply die if they don't stop swimming, because if they do, they'll suffocate to death from lack of oxygen going through their gills.

How scared of sharks are you?

If you have a phobia of them, it's called Galeophobia.

1st place for high jump

Great white sharks can jump up to 3 meters out of water. This can be seen off the coast of South Africa at sea Island. Here they launch upon their seal prey when attacking them and the force propels them out of the water.

Horrible history

Upon the sinking of the USS Indianapolis during World War II. Almost 900 sailors were left in the Philippine Sea near for 4 days. When help arrived only 316 people were still alive and no-one knows for sure how many where taken by sharks, but rumours say that the sharks had a feast.

Pound for pound

Great white sharks don't have much more of a harder bite than humans do.

Poking it's eyes may not help

When a shark attacks it doesn't close its eyelids, a great white shark instead rolls its eyes into the back of its head when it attacks. This helps the shark protect its eyes, so trying to poke them may not help as much as what we think should we get attacked by one.

Sharky smell

Sharks can detect 1 drop of blood in an Olympic sized swimming pool.

Hearty creatures

Sharks can sense your heartbeat through their sensory nodules called mpullae of Lorenzini.

Sharks are blamed for almost anything

An ancient Greek historian called Herodotus said that sharks destroyed a Persian fleet in the 5th century B.C.. This is the most likely the first time sharks were labelled with a killer reputation.
