Nature’s Strongest Fibre Comes with Conditions
The Darwin’s bark spider (Caerostris darwini), native to the forests of Madagascar, produces what scientists recognise as the toughest biological material ever measured. Its dragline silk, with a tensile strength of around 1.6 gigapascals, outperforms steel and most synthetic fibres in both strength and toughness. However, new research shows that this extraordinary property is not uniform across the species and depends strongly on body size, sex, and ecological role.
