Chroomonas reflexa is a species of cryptophyte alga in the family Chroomonadaceae, documented from freshwater environments in Europe. The specific epithet reflexa, meaning bent back or reflexed, likely refers to a characteristic curvature or reflex in the cell shape, flagella, or their attachment relative to the cell body. Cell shape and the arrangement of the ventral groove and flagellar insertion point are important taxonomic characters within the genus Chroomonas, and subtle morphological differences distinguish species that are otherwise similar in size and pigmentation. Chroomonas species are biflagellate, olive-green to brown or blue-green in color, and occur singly in the plankton and periphyton of freshwater systems. They are important components of microbial food webs, converting solar energy into organic biomass that is transferred to heterotrophic consumers. Cryptophytes are among the most nutritionally rich microalgae, containing elevated levels of long-chain polyunsaturated fatty acids (PUFAs) including EPA and DHA, making them highly valuable as food for zooplankton. Chroomonas reflexa has been recorded from European freshwater habitats. It 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.
