Darwin’s bark spider produces silk with a tensile strength of 350 to 520 megajoules per cubic meter, earning it recognition from Guinness World Records as the world’s strongest spider web. This remarkable durability enables the spider to construct vast orb webs🕸️sometimes spanning up to 2.8 square meters🕸️across rivers and streams without the web tearing under the strain of wind or large prey. Recent research shows that only female bark spiders spin this extraordinary silk. Since females are considerably larger and up to three times heavier than males, they need especially robust webs to absorb the force of bigger insects, such as dragonflies, when they collide with the web.
