Spider Web... You Are The Weakest Link....

So the Golden Orb spider doesn't produce the worlds strongest biological material anymore. Sorry spider fans.

Scientists have recently discovered an even stronger material. The tiny teeth of the Patella Vulgata Limpet in Southampton U.K. The teeth are on something resembling a tongue which the gastropod uses to scrap the rocks for algae.

The tensile strength needed to break these teeth is 3-6.5 gigapascals (GPA). If you're having a hard time relating that to the everyday (as I did), it is in the order of a strand of spaghetti holding up 3,000 pounds.

The teeth get their strength from being made by a mineral called goethite which contains iron in a fiborous structure and are encased in a protein.
