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 cattle grub

<em>Hypoderma lineatum</em>, commonly known as the common cattle grub, is a parasitic fly species with documented occurrences in Japan, Norway, Sweden, and the United States. It typically inhabited terrestrial and freshwater environments, often associated with cattle and other large ungulates on which its larvae develop as subcutaneous parasites. The species is classified as Extinct on the IUCN Red List, indicating that it is no longer known to exist in the wild. Common cattle grub belongs to the genus <em>Hypoderma</em> within the family Oestridae. Adult flies do not feed and are short-lived, while larvae burrow under the skin of host animals, causing a condition known as hypodermosis or warble fly infestation. The decline and extinction of this species has been linked to widespread and highly effective veterinary treatment programs targeting warble fly larvae in cattle, which drastically reduced host populations and ultimately eliminated the species. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature.
