The razor-sharp beaks that giant squids use to attack whales — and maybe even Captain Nemo's submarine — might one day lead to improved artificial limbs for people.

In this photo released by Tasmania Parks and Wildlife Service, a giant squid is seen after it washed up onto Ocean Beach in Strahan, Tasmania, Tuesday, July, 10. 2007.

The bodies of squid like this 3- to 6-foot-long Humboldt are extremely soft, but their beaks (not visible here) are hard and sharp enough to rip apart fish.
