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 mantoniae is a marine haptophyte alga named in honor of the pioneering British phycologist Irene Manton, whose electron microscopic studies of algal flagella and scales transformed the taxonomy of nanoplankton in the mid-twentieth century. The species belongs to the family Prymnesiaceae and displays the characteristic Chrysochromulina body plan: two heterodynamic flagella, a haptonema of variable length, and a cell surface coated with organic scales. C. mantoniae inhabits coastal marine waters of the North Atlantic, consistent with the geographic range of most formally described Chrysochromulina species. As a planktonic photosynthesizer and potential mixotroph, it contributes to the cycling of carbon and nutrients in the marine microbial food web. The haptonema's role in cell adhesion and prey capture has been studied extensively in closely related species, revealing complex behaviors including coiling and extension dynamics. The IUCN has not evaluated the conservation status of C. mantoniae, classifying it as Not Evaluated. This reflects the general absence of threat assessment methodology for free-living marine microorganisms whose populations are shaped largely by oceanographic rather than anthropogenic drivers.
