Chroococcus giganteus is a species of cyanobacteria in the family Chroococcaceae, notable for being among the largest-celled representatives of its genus, as indicated by the specific epithet. While cyanobacterial cells are generally microscopic, there is considerable variation in cell size within the genus Chroococcus, and giganteus refers to its relatively large cell diameter compared to other species in the group. Chroococcus cells are spherical to hemispherical, typically dividing by binary fission to form pairs or groups of two to four cells enclosed within layered mucilaginous sheaths. The photosynthetic pigments in the cells give them a blue-green to olive coloration. Chroococcus giganteus has been documented from freshwater and moist terrestrial habitats in various geographic regions. As a cyanobacterium, it contributes to primary production in its habitat and potentially to nitrogen cycling if it possesses nitrogen-fixing capacity. Taxonomic resolution within the genus Chroococcus remains challenging due to the limited morphological complexity of these organisms and the significant influence of environmental conditions on cell size and sheath development. The species has not been assessed by the IUCN.

Gemeine Kugelschnecke

The common bubble snail (<em>Akera bullata</em>) is a marine gastropod mollusc found in the coastal waters of Denmark, Norway, Portugal, and Sweden. This species typically inhabits terrestrial and aquatic environments including forests and freshwater-adjacent marine areas, often occurring in shallow subtidal and intertidal zones of temperate European seas. It is classified as Least Concern on the IUCN Red List. As a member of the family Akeridae, the common bubble snail is characterized by its thin, fragile shell and its ability to swim briefly by flapping its large, wing-like parapodia. The species often forages on algae and detritus in sandy and muddy seafloor habitats, particularly in sheltered bays and estuaries. The common bubble snail typically aggregates in large numbers during the spawning season, producing gelatinous egg masses. Biological traits of this species remain poorly documented in the scientific literature.
