Genetic studies have shown single species of nematode worm, newly discovered inside figs, can develop into five distinct forms.
Two that feed on microbes and three larger ones with bigger mouths equipped with rows of teeth, for catching other species of nematodes.
 It is a striking example of physical divergence without genetic divergence.
