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.

Colonial tunicate

<em>Symplegma reptans</em> is a colonial tunicate in the family Styelidae with known occurrences in Mexico, Norway, Sweden, and the United States. This species has not been evaluated by the IUCN. Colonial tunicates in the genus <em>Symplegma</em> form encrusting sheet-like colonies on hard marine substrates, including rocks, shells, and artificial structures, in shallow coastal environments. Each colony is composed of multiple filter-feeding zooids embedded in a common tunic, through which nutrients and metabolites are distributed. The presence of <em>Symplegma reptans</em> across both the North Atlantic and Pacific coastal regions suggests either a wide native distribution or a history of introduction through maritime vectors such as ballast water and hull fouling. As a sessile filter feeder, this species contributes to water column filtration and nutrient cycling within benthic communities. The reproductive biology of <em>Symplegma reptans</em> likely involves both sexual reproduction via larval dispersal and asexual proliferation through budding within established colonies. Biological traits of this species remain poorly documented in the scientific literature.
