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。

Club Grain-Spored Lichen

Sarcogyne clavus is a crustose lichen in the family Acarosporaceae, forming closely appressed, granular to warty grey-white thalli on calcareous rocks, concrete, mortar, and exposed mineral substrates. The species is characterized by its distinctive club-shaped or clavate ascospores, from which its specific name derives. Like other Sarcogyne species, it produces apothecia that are typically lecideine (lacking a thalline margin), dark-colored, and often somewhat convex. This lichen favors exposed, sunny rock faces with high calcium content, including limestone outcrops, old walls, and stone monuments. S. clavus is distributed across Europe and North America, occurring primarily in calcareous rock habitats. As a pioneer colonizer of bare rock, it contributes to the initial stages of ecological succession by weathering the substrate and accumulating organic matter. The IUCN lists this species as Data Deficient, reflecting insufficient data on its population size, distribution, and ecology to assess its conservation status with confidence. Lichens as a group are sensitive to air pollution, but calcicolous crustose lichens on exposed rock may be less vulnerable than foliose or fruticose species.
