Mindsuckers: Meet Nature's Nightmare

The world is full of parasites: mindsuckers that spread their genes by hijacking a host and turning it into a real-life zombie. The November issue of National Geographic magazine investigates the secret lives of these creatures and the lessons they hold about evolution and behavior in the natural world. Images by photographer Anand Varma show the fate of some of the parasites' unfortunate hosts.
