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.

Red Fox

アカギツネ（Vulpes vulpes）は地球上で最も広く分布する野生肉食動物であり、北半球全域とオーストラリアの移入地域において北極ツンドラから都市環境まで多様な生息地に適応している。赤みがかった茶色の毛皮、白い腹部、ふさふさした尾で識別できる。高度に適応した雑食性で、ウサギやハタネズミから果物、生ゴミまであらゆるものを食べる。40種類以上の独特な発声でコミュニケーションをとる。
