A fluke (pilot) is a parasitic flatworm that lives inside snails (capsule). Certain species of flukes possess a life cycle (flight plan) that requires them to migrate from the snail to another animal. They accomplish this by altering the snail’s brain (operating the controls), making it a light-seeking animal. Snails normally avoid light, but under the expert guidance of the fluke, the snails climb to the tops of plants where birds eat them. Bad news for the capsule, but good news for the pilot. The fluke lives on in the bird (a new world) which then distributes the fluke’s eggs.
