Parasites Can Mind-Control Animals Without Infecting Them

A tapeworm is essentially a very long, parasitic towel with a grappling hook for a head. It attaches itself to the internal organs of its host with its fiendish head spines, and it absorbs nutrients through its tagliatelle-shaped body. Once fastened, it does very little. It has no mouth or gut, no circulatory or respiratory systems. Its sparse nerves culminate in a cluster that could barely be called a brain. And yet, this very simple creature can manipulate the minds of more complex animals—even without infecting them.
