Habitat & Geographic Range

Anchovy-Eater

Habitat

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

Range

Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable 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.

Anchovy-Eater

大白鲨是地球上最大的掠食性鱼类，栖息于全球主要大洋的凉爽近岸和近海水域，体长可达6米，体重可达2,000千克。它是顶级捕食者，以海洋哺乳动物、大型鱼类和海鸟为主要猎物，从下方发动伏击。尽管声名狼藉，对人类的非激怒性攻击极为罕见。由于鱼翅贸易、兼捕和针对性捕捞，种群数量下降，尽管在许多地区受到法律保护，仍被列为易危（VU）。

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.
