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 Cottonwood

<em>Populus deltoides</em>, commonly known as common cottonwood or eastern cottonwood, is a large, fast-growing deciduous tree in the family Salicaceae. It is native to North America but has been widely planted and naturalized in Africa, Asia, Europe, and South America. Common cottonwood typically grows along rivers, streams, floodplains, and other moist bottomland habitats, where it can reach heights of 30 meters or more. The species is named for the cottony white fibers attached to its seeds, which are released in massive quantities in early summer and can create a snow-like appearance in the landscape. Its triangular, toothed leaves flutter characteristically in the slightest breeze due to their flattened petioles. Cottonwood is an important riparian tree providing habitat for birds, insects, and mammals. Biological traits of this species remain poorly documented in the scientific literature.
