大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

common blow flie

The common blow fly (<em>Calliphora vicina</em>) is a large, metallic-blue fly belonging to the family Calliphoridae. It is classified as Least Concern on the IUCN Red List and has been recorded across terrestrial and freshwater habitats in Africa, including South Africa, as well as across five European countries and the United States. <em>Calliphora vicina</em> is one of the most familiar blow fly species in temperate regions, often found around human settlements, carrion, and organic waste. It plays an important ecological role as an early colonizer of decomposing animal matter, and its predictable developmental stages make it a key species in forensic entomology for estimating post-mortem intervals. Adults typically feed on nectar, pollen, and decaying matter, while larvae develop in carrion or, occasionally, in wounds. The species is cold-tolerant and often active during cool weather when other blow flies are less abundant. Biological traits of this species remain poorly documented in the scientific literature.
