Chroococcus turgidus is a relatively large-celled species of cyanobacteria in the family Chroococcaceae, one of the more frequently cited and widely distributed members of the genus. Its specific epithet turgidus refers to the swollen or turgid appearance of its cells, which are notably rounded and plump. Chroococcus turgidus has been documented from freshwater habitats across a wide geographic range including Europe, North America, Asia, and other regions, reflecting its cosmopolitan distribution. The cells occur in pairs or groups of two to four within a stratified, often amber-brown gelatinous sheath. It is found in the plankton and periphyton of standing and slowly flowing freshwater bodies, on damp soils, and on submerged rocks and other surfaces. Chroococcus turgidus is one of the type or reference species frequently illustrated in classical treatises on freshwater algae and cyanobacteria. Its relatively large cell size compared to other Chroococcus species facilitates identification in microscopic preparations. The species contributes to primary production in freshwater ecosystems and is part of the diverse community of cyanobacteria that inhabit lentic and lotic freshwater environments. It has not been assessed by the IUCN.

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.
