Two scientists geek out over witnessing — and filming on high-speed video — the deadly strike of a net-casting spider as it captures a cricket. The delighted reaction of the scientists, who waited five hours for this to happen, is as much fun to watch as the spider’s technique. (Hint: there’s a tripwire involved.)
It’s the BBC, which means I can’t embed the video, but you can check it out here. The article is well worth reading; I hadn’t known about the actual construction of the spider’s net. That is some cool engineering! And it radically alters one’s conception of how web-spinning spiders capture prey. They don’t all sit and wait while the prey blunders into their web.
(Now thinking: I can totally see a Hollywood shriek-fest film being made with giant versions of these spiders stalking some small midwest town…)
