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.

common grey sea slug

<em>Aeolidia papillosa</em>, commonly known as the common grey sea slug, is a nudibranch mollusc belonging to the genus Aeolidia within the family Aeolidiidae. Despite the species name referencing terrestrial and aquatic habitats including forests and freshwater, <em>Aeolidia papillosa</em> is primarily a marine organism. Its range includes Belgium, Chile, Denmark, Norway, and Sweden, indicating a distribution across the North Atlantic and into South American waters. Common grey sea slug is assessed as Least Concern on the IUCN Red List. The species is typically found in intertidal and subtidal zones, where it preys on sea anemones and stores stinging cells from its prey in its dorsal cerata for defense. Biological traits of this species remain poorly documented in the scientific literature.
