Like most members of the subgenus Amphidromus, it is chirally dimorphic: within the same populations, both dextral (clockwise-coiled) and sinistral (anticlockwise-coiled) individuals co-exist. This is one of the very few cases of genetic antisymmetry known in nature. Among the subgenus Amphidromus, A. inversus stands out because since c. 2004, it has been the focus of studies aimed at understanding the evolution of chiral dimorphism. Most of these studies have taken place on the Malaysian island of Kapas.
