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 Yellow Rattle

<em>Rhinanthus minor</em>, the common yellow rattle or little yellow rattle, is a hemiparasitic annual plant in the family Orobanchaceae. It is native to Europe and parts of western Asia, occurring in traditional hay meadows, calcareous grasslands, moorlands, and other nutrient-poor grassland habitats. The species attaches its roots to those of neighboring grasses and extracts water and nutrients from them, thereby weakening grass competition and promoting the establishment of a more diverse wildflower community. This ecological role has led to the deliberate introduction of <em>Rhinanthus minor</em> in grassland restoration projects across Britain and Europe. Plants typically reach 10–50 cm in height and bear inflated calices enclosing yellow tubular flowers, which rattle when the ripe seeds are shaken — the origin of its common name. Biological traits such as precise average lifespan measurements and body weight data remain poorly documented in consolidated scientific literature. Seeds germinate only in the presence of host grass roots. The species is assessed as Vulnerable, reflecting significant declines caused by the widespread loss of traditional hay meadow management and the conversion of grasslands to intensive agriculture across much of its European range.
