Common Bithynia

The common bithynia (<em>Bithynia tentaculata</em>) is a freshwater gastropod snail belonging to the family Bithyniidae. It is classified as Least Concern on the IUCN Red List and has been recorded across terrestrial and aquatic habitats in Belgium, Denmark, Norway, Sweden, and the United States. <em>Bithynia tentaculata</em> typically inhabits slow-moving or still freshwater environments such as lakes, ponds, canals, and rivers, often on muddy or sandy substrates where organic material is abundant. The species has a distinctive operculum that seals the shell opening, providing protection against desiccation and predators. It typically feeds by grazing on algae, detritus, and biofilms on submerged surfaces. The common bithynia serves as an intermediate host for several trematode parasites, making it ecologically significant in freshwater food webs and parasite life cycles. Biological traits of this species remain poorly documented in the scientific literature.

キエリボタンインコ

キエリコザクラインコ（Agapornis personatus）はタンザニア北部の内陸乾燥地域に分布が限られる小型のオウムで、鮮やかな黄色の首輪と紫がかった青色の額が特徴です。群れを成してサバンナの低木林に生息し、ペットとして世界的に人気があるため、逃げ出した個体が各地に定着しています。IUCNレッドリストで軽度懸念（LC）に分類されています。
