Darwin's Bark Spider

Darwin's bark spider, named in honour of the naturalist who released 'The Origin of Species' 150 years prior, to the day, to its discovery on the 24th November 2009, it is an Orb weaver spider, and creates one of the largest orb webs known. It has the strongest spider silk of any spider (by almost double) and it's silk is one of the strongest biological materials of any animal alive.
