Is a Spider's Web a Part of Its Mind?
Season 7
Episode 16
Orb weaver spiders build exquisite spiral webs not only to catch insects, but to extend their senses. Once they shrink-wrap their prey with silk, the nearly blind spiders can store them for later, and read their web's strands as a kind of memory map to guide them back.
