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.

Collembola

<em>Folsomides angularis</em>, commonly referred to as Collembola in reference to its broader taxonomic order, is a springtail species belonging to the genus <em>Folsomides</em>. Springtails are among the most abundant hexapods in terrestrial ecosystems, playing important roles in soil decomposition and nutrient cycling. This species has been documented in Europe, with records from Denmark, Norway, and Sweden, as well as North America, where it is known from the United States. It typically inhabits soil, leaf litter, and decaying organic matter, and is capable of tolerating a range of environmental conditions. Springtails of this group are detritivores, feeding on decomposing plant material, fungal hyphae, and microorganisms, though specific dietary data for <em>Folsomides angularis</em> are not detailed in current records. The species has not been formally assessed for conservation status. Biological traits of this species remain poorly documented in the scientific literature. Its small body size and cryptic lifestyle make detailed ecological study challenging.
