Darwins Dark Spider

This enormous spider was discovered in 2011 in Madagascar, home to many species found nowhere else in the world. These spiders build enormous webs, as you can see, spanning everything from trees to rivers. One monster of a web was measured at 82 feet across a river.
The other unusual thing about the web the Darwin’s dark spider weaves is that it has twice the strength of any other spider silk and up to ten times the strength of Kevlar.
