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 saltmarsh grass

<em>Puccinellia maritima</em>, common saltmarsh grass, is a perennial grass in the family Poaceae, characteristic of intertidal saltmarshes along the Atlantic coasts of Europe and eastern North America, with records from multiple European nations and Canada. It is a foundational species of low and mid-saltmarsh zones, typically forming dense swards on muddy, saline substrates regularly inundated by tidal waters. The plant is highly tolerant of salinity, waterlogging, and tidal disturbance, and it plays a critical role in stabilizing saltmarsh sediments and facilitating marsh accretion. Its dense growth provides important feeding grounds for wading birds and overwintering wildfowl, and its roots and rhizomes support a diverse community of saltmarsh invertebrates. <em>Puccinellia maritima</em> is assessed as Near Threatened on the IUCN Red List, reflecting concerns about the decline and fragmentation of saltmarsh habitats due to coastal development, land reclamation, erosion, and climate-driven sea level rise. The species has declined significantly in parts of its European range over recent decades. Saltmarshes dominated by this grass also provide important ecosystem services including coastal flood buffering and blue carbon sequestration. Biological traits such as average lifespan, body measurements, and diet data remain poorly documented in standardized ecological databases.
