Chroomonas baltica is a species of cryptophyte alga in the family Chroomonadaceae, as indicated by its specific epithet, associated with the Baltic Sea region and likely occurring in brackish and coastal waters of that area. Cryptophytes are an ancient and distinctive group of eukaryotic algae whose cells contain the evolutionary remnant of a red algal endosymbiont in the form of a nucleomorph — a reduced nucleus retained from the secondary endosymbiotic event that established their plastid lineage. Members of the genus Chroomonas are small, biflagellate cells typically olive-green to brown or blue-green in color, reflecting the mixture of chlorophylls, carotenoids, and phycobiliproteins present in their distinctive cryptophyte plastids. Chroomonas baltica is likely adapted to the low-salinity brackish conditions of the Baltic Sea, one of the world's largest brackish water bodies, where salinity gradients create unique ecological conditions and specialized communities of micro- and macroalgae. Cryptophytes are important components of Baltic phytoplankton communities, contributing to primary production and serving as food for microzooplankton. The species has not been assessed by the IUCN, consistent with the treatment of most microalgal taxa.

帝企鹅

帝企鹅是世界上体型最大的企鹅，身高可达1.2米，体重达45千克，栖息于南极大陆极端恶劣的环境中。它们在隆冬的黑暗中、零下60°C以下的严寒里繁殖，雄鸟将唯一的蛋置于脚背上，藏于育卵囊下孵化长达65天，而雌鸟则在此期间出海觅食。数千只帝企鹅组成的群体通过循环交换位置、使个体轮流经过温暖的核心区域这一抱团取暖行为，堪称合作生存的典范。
