Chrysochromulina planisquama is a marine haptophyte microalga within the genus Chrysochromulina, class Prymnesiophyceae. The species epithet planisquama, from Latin meaning flat-scaled, refers to the distinctive flat or planar scale morphology of this species, contrasting with the more three-dimensional or cylindrical scales found in many congeners. Scale ultrastructure, examined through scanning and transmission electron microscopy, provides the principal diagnostic characters for separating species within this genus, where most taxa share similar overall cell dimensions and flagellar arrangements. C. planisquama has been documented from Norwegian coastal marine environments, placing it within the well-characterized northern European haptophyte fauna. Norwegian coastal and fjordic waters are cold and productive, supporting diverse phytoplankton communities in which nanoflagellates including Chrysochromulina species regularly constitute a substantial biomass fraction. The species participates in marine primary production and carbon cycling, fixing inorganic carbon through photosynthesis using chlorophylls a and c and fucoxanthin-class carotenoids. Its haptonema — the distinguishing organelle of haptophytes — may function in prey capture or attachment, potentially enabling mixotrophic feeding on bacteria. C. planisquama has not been formally assessed under IUCN criteria and retains a conservation status of Not Evaluated. The description of flat-scaled Chrysochromulina species such as this one contributes to understanding the evolutionary diversity of scale architecture within haptophytes and the relationship between scale form and function in aquatic microenvironments.

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。
