Hard? Yes

Sharp? No

As many? No way in hell!

Human teeth are one of the worst evolutionary designs ever. Why do we only get 2 sets? Why the hell are there nerves in them?

it's not about the strength or sharpness.

it's the bite pressure and size.

I thought we are supposed to punch the shark, seeing how they're not expecting you to do that, and it scares them off.

I guess biting would work too.

Sharky the friendly shark,

but not too friendly.

Not to mention the differences in shark and human skin.

Shark fin soup is pretty good. So I am okay with this!

Yup, shark bite force is about 20x greater.

/even if it was the same force, it's still 3,000 serrated teeth

Who needs evolution when you have TECHNOLOGY

Ah, the old Marv Albert defense.

That's pretty brilliant. I would never have thought of that.

I was watching a documentary called Mega-Shark vs vs Giant Octopus and I learned that mega sharks can swim at about the speed of sound.

So all this time, they could have just bitten the shark back?

Good luck with that. There's a reason why shark skin was traditionally used as durable sandpaper. It's those damned denticles, you see.

You looked up yahoo answers didn't you? Actually it's about 350 at any one time although they will go through thousands in their lifetime. Shark teeth are by far the most abundant fossil on the planet.

Below is from here Link


How many teeth do great white sharks have?


Great whites have 48 - 50 frontal teeth at any one time; 22-24 along their top jaw, and 24-26 along their bottom jaw.

Just behind this row of teeth, they can have between 5 - 7 rows of teeth ready to move into the frontal position should the shark lose a tooth, which they do, every other day.

The number of rows grow all the time. As a tooth is lost at the front, so more grow right at the back, so that the shark is never toothless at the front.

So at any one time, a great white shark can have 350 teeth in its mouth, but over a lifetime will go through thousands of teeth.

I've always used a hardline "eye for an eye" stance with sharks, and they do respect you for it. They bite you, you bite them back, and you establish a whole respect relationship.

It was on TV, so it must be true.

In other news, rock is as hard as scissors, so it should cut paper too!
