Research Abstract	Anisakis simplex, a cetacean parasitic nematode is differentiated into three sibling species by molecular based analyses, i. e. A. simplex sensu stricto, A. pegreffii, A. simplex C. Morphological differences between A. simplex sensu stricto and A. pegreffii are also reported in adult male worms cultured from third-stage larvae in an artificial medium. However in the present study, morphological differentiation in adult worms collected from the cetacean stomach is failed and the morphology of worms is diverse irrespective of sibling species.
