 Adults of the flatworm //[[http://en.wikipedia.org/wiki/Ribeiroia_ondatrae|Ribeiroia ondatrae]]// are gut parasites of aquatic birds. The eggs of the worms are released to the water through bird's feces and then hatch in a free living form that infects water snails. After a series of stages inside the snail, another swiming form --the cercaria-- is shed and infects tadpoles. The tadpoles eventually develop in adult frogs which usually have malformed limbs that make them more vulnerable to predators. Aquatic birds eat such frogs with encysted parasites and then the cycle proceeds. Adults of the flatworm //[[http://en.wikipedia.org/wiki/Ribeiroia_ondatrae|Ribeiroia ondatrae]]// are gut parasites of aquatic birds.
