Seoksella

Seoksella is a fictional genus of photosynthetic microorganisms that appears in speculative biology and science fiction. The term is not recognized by official taxonomic authorities, and its characteristics vary across sources.

In the most common fictional portrayal, seoksella comprises small unicellular or colonial forms that inhabit freshwater and brackish environments. Descriptions typically place them near biofilms on submerged surfaces, where they form ribbon-like mats. They are described as oxygenic phototrophs with pigment composition akin to green algae, possessing light-harvesting complexes and simple cell walls.

Taxonomic placement is deliberately unstable in fiction, with authors placing seoksella in different hypothetical families such as Seoksellaceae or related lineages to emphasize its ambiguous status. Some stories attribute symbiotic or parasitic relationships with bacteria or fungi to seoksella species, highlighting ecological interactions.

In literature and game design, seoksella is used to explore themes of microbial diversity, niche adaptation, and the limits of taxonomic classification. It serves as a case study for how new lineages might be described in the absence of comprehensive data.
