This statement doesn't make any sense to me... :confused:

+1 :neutral:, there are many things that can kill sharks besides old age.

Such as:
Bigger Sharks
Killer Whales
Indiscriminant long line fishing to make Shark fin soup

And the oldest trick in the book:
Compressed air canisters shot long range with riffles or cross bows.

oldest animals
 

what I mean is that short of being caught by man or eaten by bigger animals, biologically, they should live for hundreds of years. Think about it, they don't even mature and are able to reproduce until they're in their teens. Basically Cancer is natures way of strengthening the species, allowing only the strong to survive. Most animals are susceptible to cancers, except sharks. That's why they're being hunted almost to extinction, cause man wants their cartilege and fins, because we believe it will make us healthier.

Actually this is a misconception. There is no scientific evidence of this and thus remains unproven. Sharks may get cancer. My pet rock on the other hand has the immune system of a.. um.. rock!

Let's just say, for argument's sake, your rock got cancer and died....how would you tell??

I think its moss would fall out, that for sure would be a good sign.

Can you please enlighten my curious mind by amusing me and answering the following questions:

Humans don't mature or reproduce until our teens (At least I would hope :neutral:), so if the human race was impervious to cancer would we all live for ever?

If cancer is natures way of strengthening a species then why do perfectly healthy people die of it daily?

Do you personally believe it makes you healthier?

Will eating Donkey or Rat Penis make me more fertile?

No.... but will stop the lady's from kissing you.

Haha :lol:

anyone notice a trend in the longest living animals? they are all near/in the water. Maybe the sun is bad?!
