Parasitic worms are well-known for causing deadly diseases and infections, especially in animals. What’s not common knowledge, however, is how clever they are in manipulating their hosts to do their bidding.
One particular type of parasite, called the green-banded broodsac, is a flatworm that relies on snails for its life cycle. Unlike other parasites, however, this worm doesn’t actually feed off its host. Instead, it turns the snail into a “zombie” of sorts, controlling it in order to be at the right place and the right time… so it can be eaten by birds.
Why in the world would a parasite want its host to commit suicide, you ask? The answer isn’t as counterproductive as you think.
This snail looks kind of funny, doesn’t it? That’s because it’s been infected with a parasitic worm, called the green-banded broodsac, which takes up residence inside its tentacles. The parasite now has complete control of the snail’s brain—and it’s instructing the doomed gastropod, nicknamed a “zombie snail,” to climb to the tops of plant stalks in broad daylight.
