Except for its larger mature size, this species is closely similar in overall shell morphology and radular and jaw structure to the wide spread species N. pompilius Linnaeus in the Southwest Pacific. This fact and available genetic data suggest a possibility that N. belauensis merely represent s a geographic variant on N. pompilius with high levels of morphological and genetic differentiation.}, pages = {41--55}, title = {Morphological Analysis of Living Nautilus from Palau}, volume = {27}, year = {} }
