An approximately three-foot-wide (meter-wide) Darwin's bark spider web hangs above a river in Madagascar.Though the new species' webs are overall the world's largest, other spiders might exist that create larger orbs—the spiral at the center of the web—according to study co-author Todd Blackledge, a biologist at the University of Akron in Ohio.
Despite spinning webs of Spider-Man-like size and strength, the Darwin's bark spider uses them to feed mainly on small fry—insects such as mayflies and dragonflies, the team found.
