Biosystematics is the science through which life forms are discovered, identified, described, named, classified and catalogued, with their diversity, life histories, living habits, roles in an ecosystem, and spatial and geographical distributions recorded. In essence, it is biosystematics, the science that provides indispensable information to support many fields of research and beneficial applied programs.

We love and appreciate nature one way or another. Peculiar shapes, attractive colors, and curious daily activities of many life forms occurring around us, plants and animals alike, greatly stir our curiosity. We have learned to know many of these life forms through observation and experience. In order to be able to recognize these living organisms again and again, we have to apprehend and record characteristics of their appearance, habits and various other aspects, and give each a unique name. In fact, everyone of us, in this context, is a "biosystematist".
