Darwin’s Bark Spider
[dx_custom_adunit desktop_id=”RTK_K67O” mobile_id=”RTK_5yk0″]
In addition to being named after the noise I make when I see one, Darwin’s bark spider produces a web that is ten times stronger than Kevlar. The spiders cast these webs over bodies of water to catch unlucky flying insects. They don’t need larger prey, though. According to evolutionary biologist Todd Blackledge, “a bird or bat would be such a tremendously large meal that a spider might only need to capture them once or twice over its lifetime.”
