BBC - Earth News - Gigantic spider's web discovered in Madagascar: "A newly discovered species of spider living in Madagascar makes the world's longest known web, spanning 25 meters. The spider also makes the largest orb web yet found for any spider, and constructs it out of the most tough biomaterial yet known, say scientists. Darwin's bark spider, a species new to science, weaves its huge web over flowing rivers, stretching from bank to bank. It is so big that it can catch 30 or more prey insects at any one time."
