Kim Rogers walks through images of what parasites can actually look like under a microscope, starting with a tapeworm. It latches into the stomach using fang-like structures, then winds through the intestines, absorbing nutrients directly through its body rather than eating in any conventional sense.

Each segment, roughly the size of a grain of rice, can contain 46 uteruses and produce up to a million eggs a day. Because it's latched on, removing a tapeworm requires getting the head out specifically, not just the visible segments.
