bolas spiderInstead of spinning a traditional web, the aptly named Bolas Spider uses its spinnerets to spin something a little more badass: A line of silk with a sticky 'capture blob' on the end called a bolas. It's the thing that gauchos use to hunt, only tiny and made by a spider.

When the time is right (i.e., a moth is passing by), spidey hurls its bolas at its prey, and if all goes well, it climbs down for dinner. And they used to say animals don't use tools!
