Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 9 distinct biome types spanning the Australasia and Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across India, Indonesia, Myanmar, Sri Lanka, and Thailand. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Bithynia

Habitat

Typically found in terrestrial and aquatic habitats including forests and freshwater.

Range

Distributed across Belgium, Denmark, Norway, Sweden, and United States.

Asiatic elephant

アジアゾウ（Elephas maximus）はアフリカゾウに比べて小型で、インドから東南アジア・インドネシアに至る森林・草原に生息する。アフリカゾウより小さな耳・丸みのある背・鼻先の1本の指状突起などの形態的特徴を持ち、アジアの文化・宗教と深く結びついており、古来より使役動物・神事に用いられてきた。IUCNレッドリストでは絶滅危惧（EN）に分類されており、野生の個体数は5万頭を下回る。

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.
