World’s Biggest, Strongest Spider Webs Found

A river-spanning spider web dwarfs a park ranger in Madagascar in 2008. Made of the world’s strongest known biological material, the web is the product of a new species, the Darwin’s bark spider, which makes the world’s largest webs of any single spider, new studies say.

Zoologist Ingi Agnarsson and colleagues have found Darwin’s bark spider webs as wide as 82 feet (25 meters)—about as long as two city buses.

In Andasibe-Mantadia National Park (pictured), “the park rangers knew about them, and I think they’ve shown them to tourists for a while,” said Agnarsson, of the University of Puerto Rico.
