Asettamia

Asettamia is a fictional genus of microscopic, photosynthetic protists used in educational material to illustrate taxonomy and evolutionary relationships. In the imagined classification, Asettamia is placed within the eukaryotic domain and the kingdom Protista (or Protoctista in some systems). The provisional family Asettamiaceae contains the genus Asettamia and several species that are described only in didactic contexts.

Origin and etymology: The genus name derives from a fictional researcher, L. Asett, and is intended to show how new genera might be named in line with binomial nomenclature used in biology classrooms.

Description: Members are typically 3–12 micrometres in diameter and can be found as solitary cells or simple colonies. They are photosynthetic with chlorophylls a and c and often display a pigmented appearance described as green to blue-green. Morphology ranges from spherical to disc-shaped, and most strains are motile by a single anterior flagellum, though some are nonmotile in certain life stages.

Life cycle and reproduction: Reproduce mainly by binary fission; cyst-like dormant stages can form under adverse conditions, illustrating basic concepts of asexual reproduction and survival strategies.

Habitat and ecology: In the fictional scenario, Asettamia species inhabit freshwater ponds and slow streams in temperate regions, contributing to primary production and forming ephemeral biofilms on submerged surfaces.

Species example: Asettamia cerulea and Asettamia rubra are used in teaching to illustrate color-based species concepts, not real taxa.
