Parasitic Disco Worms: Snail Mind Control
Eplains the extraordinary parasitic behavior of the Green Banded Brood Sac, a flatworm that invades the bodies of amber snails and manipulates them into becoming hosts for its next life stage. Once inside, the parasite fills the snail’s eyestalks, causing them to swell, pulse, and flash with bright colors that resemble a caterpillar, luring birds to eat the snail. After being consumed, the flatworm reproduces inside the bird’s digestive system, and its eggs exit through droppings, which are later eaten by other snails—continuing the cycle. The parasite’s control is so complete that it forces the nocturnal snail to move into daylight, maximizing the chances of predation. The text also mentions other similar flatworms but clarifies that this species poses no risk to humans.
