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.

Common stork's bill

<em>Erodium ciconium</em>, the common stork's-bill, is an annual or biennial flowering plant in the family Geraniaceae, order Geraniales. It is native to the Mediterranean region and southern Europe and has been introduced to parts of North America. The species typically inhabits dry, disturbed habitats including roadsides, cultivated fields, rocky slopes, and coastal areas, favoring sandy or calcareous soils with good drainage. Its pink to purple flowers are relatively small, and the distinctive elongated fruit resembles a stork's bill, a characteristic shared across the genus <em>Erodium</em>. The beak-like fruits are adapted for wind and animal dispersal, with hygroscopic awns that drill the seed into the soil through coiling movements in response to moisture changes. Biological traits such as typical lifespan duration, average biomass, and detailed dietary associations remain poorly documented at the species level. <em>Erodium ciconium</em> has not been formally evaluated by the IUCN, though it is generally considered a common species without significant conservation concern across most of its range.
