Chroomonas reflexa is a species of cryptophyte alga in the family Chroomonadaceae, documented from freshwater environments in Europe. The specific epithet reflexa, meaning bent back or reflexed, likely refers to a characteristic curvature or reflex in the cell shape, flagella, or their attachment relative to the cell body. Cell shape and the arrangement of the ventral groove and flagellar insertion point are important taxonomic characters within the genus Chroomonas, and subtle morphological differences distinguish species that are otherwise similar in size and pigmentation. Chroomonas species are biflagellate, olive-green to brown or blue-green in color, and occur singly in the plankton and periphyton of freshwater systems. They are important components of microbial food webs, converting solar energy into organic biomass that is transferred to heterotrophic consumers. Cryptophytes are among the most nutritionally rich microalgae, containing elevated levels of long-chain polyunsaturated fatty acids (PUFAs) including EPA and DHA, making them highly valuable as food for zooplankton. Chroomonas reflexa has been recorded from European freshwater habitats. It has not been assessed by the IUCN.

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.
