DARWIN’S BARK SPIDER
Darwin’s bark spider, is a 3/4” (19mm) a type of orb spider, weaves webs that span rivers and lakes — one web reached 82 feet (25 meters) in length, giving the species the title of the world’s largest web spinner. The length of the webs allow the Darwin’s bark spider to capture insects (30 mayflies and dragonflies noted in one web) in a niche otherwise unexploited by spiders.
The silk of the species is also the strongest biomaterial ever encountered. The web is twice as resilient as the next strongest silk and 10 times tougher than Kevlar, the material used in bulletproof vests.
Scientists will continue to study the Darwin bark spider. Some researchers believe the spiders could one day benefit humans. They think the silk could be used to create artificial muscle tissue. Source
