African elephant

非洲象是地球上体型最大的陆地动物，体重可达7,000千克，栖息于撒哈拉以南非洲的草原、稀树草原和森林中。作为关键种，它们通过挖掘水源、传播种子和改变植被结构，深刻塑造了其栖息地的生态系统。受栖息地丧失和象牙盗猎威胁，非洲象的保护至关重要。

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.
