Chrysococcus biporus is a unicellular chrysophyte alga in the genus Chrysococcus, family Chromulinaceae. Like all members of the genus, the cell is enclosed within a loricate cell covering — a firm, often flask-shaped structure known as a lorica that surrounds the protoplast. The epithet biporus (Latin: two-pored) describes the two openings or pores present in the lorica, through which the flagella emerge. Chrysococcus cells are typically uniflagellate (or with a short, hair-like second flagellum), heterotrophic or mixotrophic, and capable of both photosynthesis and phagotrophic ingestion of bacteria and small organic particles. The genus inhabits freshwater and brackish environments, including oligotrophic and eutrophic lakes, ponds, and wetlands. C. biporus has been recorded from Scandinavian waters, consistent with extensive chrysophyte survey effort in northern Europe. Chrysophytes as a group are important components of freshwater protist communities, playing roles as grazers of bacteria and as prey for larger zooplankton. The species has not been evaluated for conservation status and is listed as Not Evaluated by the IUCN. Molecular surveys are continuing to reveal undescribed diversity within the loricate chrysophyte lineages.

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.
