Imposex Study on Thais tuberosa from Port and Non-Port Areas along the West Coast of Peninsular Malaysia

Imposex was found to occur among Thais tuberosa snails collected from eight locations, consisting of port and non-port areas, along the west coast of Peninsular Malaysia. All (100%) female individuals of this species were found to have male sexual characteristics (imposex) at various stages. The hig...
