Baeomyces placophyllus is a crustose lichen with a thick, squamulose thallus bearing distinctive, unbranched podetia topped with pale, flesh-colored apothecia. It inhabits bare, acidic mineral soils in open heathland, moorland, and alpine environments in temperate and boreal Europe. This lichen is considered endangered due to habitat loss from soil stabilization and grassland improvement.

common bubble snail

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.
