Fun Facts About Sharks

Sharks have evolved in the past 470 million years and unbelievably there are about 440 different species!

Sharks are loners and hunt and live by themselves.


Unlike other fishes, sharks do not have bones, and their skeleton is entirely made up of cartilage (Tough elastic tissue. Top of your ear is made of cartilage).

Sharks can swim at up to 35 miles per hour, but they can do this only for short distances. 

Amazingly they can survive in river and sea water.

The Bull Shark actually changes things in its blood to survive in both river and sea water. That’s amazing, wonder how he does that!

Incredibly, Sharks have to continue to swim to breathe, as they cannot otherwise push water through their gills.

Hammerhead sharks have 360 degree vision, they can see all around them, how cool is that!

Shark Skin

Apparently shark skin can be used as sandpaper. MythBusters tested it and apparently it works really well.

It is soaked in wee overnight; now that’s really gross!

Then they dry it out before using it! A shark’s skin is made of tiny scales which point towards the tail.

What this means is that there is no resistance while they’re swimming in the water so it doesn’t slow them down.

But if you rub the skin from tail to head, it feels really rough, just like sandpaper. Now that’s really weird.


Shark Teeth

Did you know that a shark never ever runs out of teeth?

They have between 5 to 15 rows of teeth arranged in layers.

Imagine having rows of teeth in your mouth? It would certainly feel quite strange don’t you think.


One Bull Shark was found with 50 rows of teeth! He must have one seriously big mouth.

If a tooth breaks off, another one grows in its place within a day. They can grow up to 50,000 teeth in a lifetime.  That is incredible.

They can grow and lose over 20,000 teeth in their lives.When a shark dies their teeth don’t rot. They do eventually, but it takes about 10,000 years for this to happen. Wow!

When a baby shark is born it already has teeth and can swim away and defend itself immediately.

The Great White Shark has 4 times the bite force of a lion or a tiger,  imagine that!

Items Found Inside Sharks

This will make you laugh! There have certainly been some weird and wonderful things found inside sharks!

They have found tyres, bike parts, tin cans, a polar bear, a 16th-century Portuguese medallion, license plates, boots, fur coats, and the bones of an adult, a 7 foot (2 metre) long dolphin, and bottles of wine.


They also found the remains of a knight still wearing his armour.

It was apparently found inside a Great White Shark in the 16th Century, although some people really don’t know if this is true.

They’ve also found a cannon ball, porcupines, cans of paint, livestock and crocodile heads, a reindeer with their antlers, rubber boots, pet dogs with their collars, a camera while it was still running, a horse head, a bag of money, and Barbie dolls!

Also, crazily enough, another shark had a chicken coop with chickens still inside.

It seems sharks have a taste for almost everything!


What should you do if you meet a shark in the water?

Sharks might look very scary and for centuries people have thought that they are just man-eaters, but they are actually gentle and quite like being touched by humans.

In Cape Town, South Africa, the Foster brothers used a film to prove this point.

Damon Foster says surfers should paint a big eye on their board and make sure the board isn’t shiny or glittery.


If a shark comes, the surfer should get off the board into the water, make him or herself as ‘big’ as possible and eyeball the shark.

That way the shark knows the surfer isn’t afraid and will back off. If the surfer tries to high tail it out of there, the shark then thinks that they are prey and will go on the hunt.

Well now you know what to do…get painting that big eye on your surfboard.

Mike Rutzen is South Africa’s ‘shark whisperer’! He cuddles sharks, puts them into a trance by tickling their sensory spots which are usually found under their snout, and takes rides on their backs by holding their dorsal fins.

Who would have thought that they could be so gentle? How awesome is that?
