African elephant

非洲象是地球上体型最大的陆地动物，体重可达7,000千克，栖息于撒哈拉以南非洲的草原、稀树草原和森林中。作为关键种，它们通过挖掘水源、传播种子和改变植被结构，深刻塑造了其栖息地的生态系统。受栖息地丧失和象牙盗猎威胁，非洲象的保护至关重要。

common hydra

<em>Hydra vulgaris</em>, commonly known as the common hydra, is a small freshwater cnidarian in the family Hydridae. Its conservation status has not been formally evaluated by the IUCN. The species is recorded from Denmark, Norway, and Sweden, with its native range understood to encompass Europe broadly. It typically inhabits slow-moving or still freshwater bodies such as ponds, lakes, and streams, where it attaches to aquatic vegetation or submerged substrates. The common hydra is notable for its remarkable regenerative capabilities and has been the subject of substantial biological research. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
