When people think of spiders, it's the webs or the bites that get most of the attention. But what always blew me away was the careful perception a spider requires. From picking a suitable area to web, to dancing carefully across the strands, to sensing a snared prey and knowing whether to feast or flee, the spider is always aware. Their eyes may not be all that great, but they perceive a much larger cognitive space than a lot of their buzzing cousins. How does such a clever mind get encoded to such a small physical form?
