Clastidium setigerum is a filamentous cyanobacterium in the family Clastidiaceae, characterized by producing tapering filaments anchored to substrates by a basal holdfast cell. It grows on coarser algae, invertebrates, and rocky substrates in freshwater or marine environments. Its single, hair-like trichome ending in a long colorless hair is a distinctive morphological feature of this genus.

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.
