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.

Olivbrauner Rötling

Entoloma versatile is a small to medium-sized Entoloma mushroom with variable coloration in shades of grey, brown, or olive, and the characteristic pink spore print of the genus. It grows in grasslands, woodland edges, and scrubby habitats across temperate Europe. Near Threatened, its rarity is linked to the decline of ancient, unimproved grasslands under agricultural intensification.
