Reply to comment by ZirePhiinix in TIL California killifish infected with a trematode flatworm are 10 - 30 times more likely to become meals for birds than uninfected fish by mankls3

Nice, ok, so I was assuming:

Infected fish swim closer to the water to be eaten by birds
The flatworms reproduce in the bird; flatworm eggs are shed in bird waste
Fish eat the bird waste and get infected

I remember that for toxoplasmosis, they could only reproduce inside cats
