I had to google it. "The limpet, an aquatic snail that feeds by scraping algae off of rocks, has been found to have teeth that exceed the tensile strength of spider silk, Kevlar, and titanium.
Researchers measured that the amount of force required to break the millimeter long teeth is about the same pressure that it takes to turn carbon into diamond in the Earth’s crust". - a probably reputable website.
@Red23, eh, reputable enough
@Red23, so, wikipedia
I really do not believe you
@open name, oh you're gonna be surprised.
Organic material is mostly carbon. Are you saying a snail turns its mouth into diamond whenever it eats?
@Kierkegaard, I think the calcium just has a favorable lattice arrangement that makes it EFFECTIVELY stronger in the biting direction.
If you struck a tooth from any animal along a cleavage plane, it would probably have the strength of chalk.
Ehh... IDK man, if you say so.
