The newest contender for the strongest material is found in the sea. Science has discovered recently that teeth belonging to tiny marine creatures called limpets are so incredibly tough they could be used to construct boats.
The chompers are 100 times thinner than the diameter of a human hair. Scientists have determined that if we built huge structures from material fashioned from limpet teeth, they would be as strong and unbreakable as the smallest piece of the material – a massive advantage for engineering.
Limpets are snail-type creatures crawling along the sea bed, carrying their portable, cone-shaped homes with them. Scientists decided to use a process known as atomic force microscopy on a set of limpet teeth to test how the material behaves at a microscopic level, and how strongly it bonds together.
