Ancient sea worm had jaws made of mysterious bio-metal, scientists find

Marine worms possess jaws built from proteins and metal ions, creating bio-metals. These bio-metals exhibit high hardness and a specific response to strain. Researchers discovered a size-dependent elasticity in these worm jaws. This phenomenon is similar to traditional metals like copper and silver. Studying these natural bio-metals could inspire new human-made materials.
