Piranha vs. Arapaima: Engineers Find Inspiration for New Materials in Piranha-proof Armor
February 8, 2012
It's a matchup worthy of a late-night cable movie: Put a school of starving piranha and a 300-pound fish together, and who comes out the winner? The surprising answer--given the notorious guillotine-like bite of the piranha--is Brazil's massive Arapaima fish. The secret to Arapaima's success lie in its intricately designed scales, which could provide "bioinspiration" for engineers looking to develop flexible ceramics.
