Darwin's bark spider (Caerostris darwini) is an orb-weaver spider that produces the largest known orb webs, ranging from 900 to 28,000 square centimetres (140 to 4,340 sq in),[2][3] with bridge lines spanning up to 25 metres (82 ft). The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009.[4] Its silk is the toughest biological material ever studied. Its tensile strength is 1.6 GPa.[5] The species was named in honour of the naturalist Charles Darwin on November 24, 2009—precisely 150 years after the publication of The Origin of Species.[2]
