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 horse fly

<em>Haematopota pluvialis</em>, commonly known as the common horse fly, is a blood-feeding dipteran insect in the family Tabanidae. It is classified as Least Concern on the IUCN Red List. The species is recorded from Belgium, Denmark, Norway, and Sweden, with a distribution centered in northwestern Europe, where it typically inhabits moist, vegetated areas near water bodies, woodland margins, and pastures. Female horse flies are well known as ectoparasites of large mammals, while males are primarily nectar feeders. Diet information beyond this general feeding ecology is not available in current species records. Biological traits of this species remain poorly documented in the scientific literature.
