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。

哥伦比亚鸊鷉

<em>Podiceps andinus</em>, commonly known as the Colombian Grebe, is a bird species belonging to the genus <em>Podiceps</em> within the family Podicipedidae. This species is classified as Extinct, with the last confirmed sightings recorded in the 1970s at Lake Tota in Colombia, its sole known location. The Colombian Grebe was endemic to Colombia and is believed to have been primarily restricted to that high-altitude lake. A record from Norway in available data likely reflects a historical or erroneous entry rather than a genuine occurrence. The species inhabited various aerial, terrestrial, and aquatic environments in the context of its lake ecosystem, diving for fish and other aquatic prey in the manner characteristic of grebes. Habitat drainage for agricultural purposes, hunting, and pesticide contamination of its lake habitat are considered the primary drivers of its extinction. Dietary information specific to this species has not been documented, though grebes typically consume fish and aquatic invertebrates. Biological traits of this species remain poorly documented in the scientific literature. The extinction of <em>Podiceps andinus</em> is considered one of the notable avian losses of the twentieth century in South America.
