The study was focused on the colour polymorphism, behaviour & abundance of ecologically & economically important species Umbonium vestiarium. Different polymorphism pattern showing in Umbonium vestiarium during study with various aspects like band design & whorl design. Study reveals that, this ecologically important species can be conserved through reducing anthropogenic activity. Polymorphism and behaviour study can give new aspect at genetic diversity in Button Shells.
