Which brings me on to a real life Mega shark......

What? You thought the folks behind the Mega Shark series had just made it up?

Don't be silly.

Well... they exaggerated. A lot. But the real life monsters that inspired those, uh, interesting movies were still pretty bloody impressive.

Take the Carcharondon Megalodon:
Now that's a name with teeth. Literally - it means 'Mega tooth Shark'.

Which fits this prehistoric beast quite nicely, as its was a twenty meter (sixty foot) long shark with a bite force of up to a hundred and eighty thousand newtons. That makes it a swimming car crusher

As one palaeontologist put it: "Megalodon ate whatever it liked"

With teeth this big we can see why:

Luckily they all died out over a million years ago.....

...welllll.... as far as we know they did. But the armoured Coelacanth fish turned out to still be alive, and that was supposed to have died out sixty five million years ago.....

The Coelacanth with a diver: Still kicking after sixty five million years. Well, metaphorically kicking, as fish have no feet....
