大齿蟾

The Common Lazy Toad (<em>Oreolalax major</em>) is an amphibian in the family Megophryidae, classified as Least Concern on the IUCN Red List. The species typically inhabits freshwater habitats, moist forests, and wetlands, favoring cool, humid environments associated with mountain streams and adjacent riparian vegetation. As a member of the family Megophryidae, it is adapted to fast-flowing, clear mountain streams where larvae typically develop among leaf litter and gravel on the stream bed. The Common Lazy Toad is generally associated with the highland and montane zones of its range, relying on intact forest cover and unpolluted water bodies for reproduction and larval development. Its Least Concern status reflects an assessment of stable population trends, though like many amphibians it may be sensitive to changes in water quality, habitat loss, and emerging infectious diseases such as chytridiomycosis. Biological traits of this species remain poorly documented in the scientific literature.

虎鯨

作为海豚科体型最大的成员，虎鲸（Orcinus orca）体长可达9米，体重6吨，分布于从北极到南极的所有海洋。以母系群体生活的顶级捕食者，不同种群具有独特的方言、狩猎策略和文化传统。一些种群专门捕食鱼类，另一些则捕食海洋哺乳动物。没有天敌，虎鲸位于其所栖居的每条海洋食物链的顶端。
