Strongest Biological Material is... Limpet Teeth


Who would have thought this?  For several years, scientists thought the strongest biological material was spider web.  Now it turns out that it is a tooth!

A sea snail called a Limpet is the owner of these little miracles... and I *do* mean little.  The teeth are only roughly 1 millimeter in height.  Tiny but tough.

Why are these teeth so strong?  Well limpets attach themselves to rocks that are underwater & near the shore.  The feed on algae.   So when they eat, the scrape their teeth on the hard surface of the rock.  Therefore their teeth *have* to be strong.  Stronger than human teeth... stronger than any other teeth known to man.

Perhaps we can learn something from this.  Maybe there's a new really tough material on the  horizon.  I'll leave that to the researchers, however, this is a really cool & interesting discovery.
