from non-rigid cells with intercellular junctions. Whereas the other complex,
multicellular forms of life on earth (i.e., plants and fungi) opted for rigid cell
walls, Class Animalia followed a different road. The fundamental biological
feature that characterizes animals and distinguishes animals from all other
organisms, can be traced to soft cells and specialized junctions.
