  We exhibit a wide variety of the nuclear shape phases over the nuclear chart
along with a shell model scheme. Various nuclear shapes are demonstrated within
the framework of proton-neutron spin-orbital interactions; ferro-deformed,
sub-ferro-deformed, and spherical shapes. The spherical shape is classified
into the three magic-number categories in view of a large shell gap mechanism;
double-magic nuclei I, double magic nuclei II, and double magic nuclei III. We
discuss nuclear shape coexistence in the space Z = 76 to 84 as providing a new
way to understanding the dynamical shape phases.
