Organismides

Organismides (singular organismide) is a rarely used term that appears in speculative biology and philosophy to denote a discrete life unit that sits between cells and whole organisms. It is not part of formal taxonomic classification and has no standard definition in recognized biological nomenclature.

Origin and usage: The word derives from organism + ide; usage is limited to science fiction or theoretical discussions about individuality, modularity, and emergent life. In these contexts, an organismide may be described as a self-sustaining, autonomous unit capable of reproduction and environmental response, or as a modular unit that can combine with others to form larger life systems or superorganisms.

Relation to other concepts: It is distinct from cells, organisms, and superorganisms in that it is used as a conceptual unit rather than a fixed biological category. Some discussions compare organismides to holons or to modular organisms, while others use it as a thought experiment about levels of biological organization.

Current status and examples: There are no widely accepted criteria or definitions, and the term appears sporadically in non-peer-reviewed contexts. It is mainly of interest to those exploring questions of individuality, emergent properties, or speculative life forms.
