| Abstract: | The eight species of nematode larvae from marine fish in Taiwan Strait were studied with the clustering analysis of Euclidean taxonomic distance and principal components analysis (PCA), based on about fifteen structural characters of nematodes commonly used in traditional classification show similar results. Multivariate analysis indicated that environmental factors, notably host species, have effect on the morphology of marine-fish parasitic nematodes. Among characters, the PCA shows that, the characteristics describing the relative morphometric of , the alimentary canal and its appendix and some organs' relative position may play important roles in the taxonomy of nematodes. The ordination of the structural characters of nematodes obtained by PCA could further explain the relationship between species and then determine whether exist morphological and species difference. |
