The spiders, it was later realized, were not reacting to flooding, they were warning of the invasion coming on the subspace webs…Recently, in real life, it was discovered that, like bees, spiders in colonies can communicate in simple ways. So, they’ve been talking and talking and showing…but we don’t listen. “Oh certainly, we are sometimes adversaries, but we have no wish to see our planet fall to an invasive species. These invaders, as we well remember from 65 million years ago, can spread amongst us quite quickly. Only the willingness of the dinosaurs to sacrifice themselves to the fight kept the things in check. We had some of the surviving invaders wrapped in webs–for in those days we were each bigger than kangaroos–and they went dormant, deep underground. But now they stir, sensing their fellows arriving…Hey, Seven-Leg, dude, they’re not listening…perhaps we should just spread out and eat them, at least that way…oh, okay, private council…”
