Net-casting spider: “She’s a superb creature.”

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…)

    I’ll bet it’s just pure coincidence that the ad that ran before that video was an Oregon tourism spot. 😉

    Fantastic! Surely I’m not the only one who has watched umpteen times those exciting seconds in the middle of the video. Fantastic!!!
