...ite finds the developing limb bud where it forms a cyst and sits between the cells that will become the limbs of the frog that the tadpole will turn into. By interfering with the tadpoles limb development, the parasite causes the frog to become deformed, often by making extra or missing limbs. This defo...JCI table of contents, 15 March 2004

According to the researchers, the story of the parasitic trematode reveals just how complicated natural ecological processes can be, and how difficult it is to trace problems to their underlying cause. ...Deformed frogs form when parasites and pesticides combine
