The Brittlestar (Amphiura filiformis) is a species in the genus Amphiura. It is currently classified as Least Concern on the IUCN Red List. Native to Europe, inhabiting ecosystems characteristic of the region.

Chroococcus dispersus is a species of cyanobacteria in the family Chroococcaceae, occurring in freshwater habitats including lakes, ponds, and slowly flowing waters. It belongs to a genus characterized by small, spherical cells grouped in pairs or quartets within a diffuse, hyaline sheath. The specific epithet dispersus suggests a tendency for cells or colonies to be loosely organized or widely distributed. Cyanobacteria in the genus Chroococcus are typical components of the plankton and periphyton of oligotrophic to mesotrophic freshwater bodies in temperate and boreal regions. They are photosynthetic, using sunlight and dissolved carbon dioxide to produce organic matter, and contribute to primary productivity in aquatic ecosystems. Some Chroococcus species can also fix atmospheric nitrogen under nitrogen-limited conditions, though this trait is more pronounced in filamentous cyanobacterial genera. Chroococcus dispersus has been identified from European freshwater systems and is representative of the diverse microfloral communities found in clean to moderately enriched freshwaters. It is not assessed by the IUCN and has no known economic significance, representing one of many microscopic components of aquatic biodiversity.
