Trematodes Live Inside Snails In Moist Environments. They Glide

By Aase Berg

Trematodes live inside snails in moist environments. They glide
up the snails’ antennae and start to blink. That is how they cause
the host animal to climb up a reed where a little light show takes place.
A bird is drawn to the light and it swallows the snail.
The trematode has now found its home inside the bird,
where it wanted to end up!
