Chroomonas acuta is a species of cryptophyte alga in the family Chroomonadaceae, found in freshwater and brackish aquatic environments. Cryptophytes are biflagellate, unicellular algae characterized by the presence of a unique organelle called the nucleomorph — a remnant nucleus from a secondary endosymbiotic event in which an ancestral flagellate engulfed a red alga. This evolutionary heritage is reflected in the distinctive combination of pigments in the plastid, including chlorophyll a, chlorophyll c, and phycobiliproteins such as phycoerythrin and phycocyanin, which give cryptophytes their often blue-green to red-brown color. Chroomonas species are small flagellates that swim using two unequal flagella arising from a ventral groove. They are important members of freshwater phytoplankton communities, particularly in the cold-water picoplankton. Chroomonas acuta has a more pointed or acute cell shape compared to some related species, as indicated by its epithet. The species has been documented from European freshwater habitats. Cryptophytes contribute to primary production in freshwater and marine ecosystems and are a significant food source for heterotrophic protists and filter-feeding zooplankton. The species has not been assessed by the IUCN.

Chroomonas dispersa is a species of cryptophyte alga in the family Chroomonadaceae, found in freshwater and brackish aquatic environments. The specific epithet dispersa suggests a widely scattered or diffuse distribution or cellular arrangement. Cryptophytes in the genus Chroomonas are small, motile, unicellular flagellates widely distributed across freshwater, brackish, and marine environments globally. They are particularly important constituents of the nanoplankton and picoplankton size fractions in many aquatic systems. The combination of photosynthesis and occasional mixotrophy — the ability to ingest bacteria or dissolved organic matter — in some cryptophyte lineages gives these organisms metabolic flexibility that contributes to their ecological success across a range of trophic conditions. Chroomonas dispersa has been documented from European freshwater habitats and contributes to the baseline biodiversity of these systems. Cryptophytes as a group have been studied for their potential in biotechnology, including as sources of polyunsaturated fatty acids and natural pigments. The species has not been assessed by the IUCN.
