vitamus

Vitamus is a fictional genus of aquatic photosynthetic organisms described in speculative biology. It is used in educational and fictional contexts to explore concepts such as ecosystem engineering, microbial-plant symbioses, and the potential impacts of synthetic biology on aquatic systems.

In the imagined taxonomy, Vitamus forms small, branching thalli up to 2–4 cm long, composed of filamentous cells with a green pigment mixture including chlorophylls a and b and accessory carotenoids. Colonies often create bright green to olive mats on submerged surfaces. Cells are motile with two flagella in the free-moving stage.

Vitamus is placed provisionally within Chlorophyta in speculative classifications, with a putative family Vitamaceae. The genus name derives from vita, Latin for life, and mus as a common suffix in the fictional taxonomy.

In the fictional setting, Vitamus is endemic to brackish tidal pools on the Archipelago of Axios, though it is depicted as capable of surviving a range of salinities and light levels in experimental environments.

Vitamus often forms mutualistic associations with nitrogen-fixing bacteria and microalgae. Reproduction occurs through autospores produced in specialized sacs and through fragmentation of the thallus; sexual reproduction is described as rare in the fiction.

The genus was first described by botanist L. R. Kestrel in 2142 in the Journal of Speculative Botany. It is commonly cited in discussions on modeling fictional ecosystems and the consequences of introducing novel aquatic taxa.
