Gliding Spiders

Other wingless insects, including some ants, can glide too. But Dr Yanoviak found himself wondering if any invertebrate that was not an insect could manage the trick. In particular, he knew of no arachnid that could. He and his colleagues therefore started throwing arachnids out of trees in their research sites to see what happened.

That last sentence is what I love about academic research – so much of it is just “why the hell not?”
