  The philosopher Jack A. Wilson examines some boundary cases to demonstrate that the concept of organism is not sharply defined. In his view, sponges, lichens, siphonophores, slime moulds, and eusocial colonies such as those of ants or naked molerats, all lie in the boundary zone between being definite colonies and definite organisms (or superorganisms).
