Cheetah

猎豹是地球上奔跑最快的陆地动物，在非洲和伊朗草原上短距离冲刺速度可达112千米/小时。体型纤细，胸深腿长，具有标志性的黑色泪纹。与其他大型猫科动物不同，猎豹以吱鸣声和咕噜声交流。由于栖息地碎片化和与更大型捕食者的竞争，猎豹被列为易危，野外仅剩约7,000只。

Chrysochromulina pringsheimii is a haptophyte microalga in the family Prymnesiaceae, named for the German botanist Nathanael Pringsheim, who made foundational contributions to algal biology in the nineteenth century. The species follows the Chrysochromulina body plan: a biflagellate cell with a haptonema and a surface coat of organic scales arranged in overlapping layers. Scale morphology observed under electron microscopy provides the principal characters used to distinguish C. pringsheimii from related species. The species is found in marine and occasionally brackish coastal waters of northern Europe, consistent with the biogeographic concentration of described Chrysochromulina diversity in Scandinavian seas. As a nanoplankton primary producer, it participates in carbon fixation and the transfer of photosynthetically fixed carbon to higher trophic levels via grazing by heterotrophic nanoflagellates and microzooplankton. Some Chrysochromulina species produce dimethylsulfoniopropionate, contributing to the oceanic sulfur cycle. The conservation status of C. pringsheimii has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Global environmental sequencing suggests that the diversity of haptophyte nanoflagellates in the world's oceans greatly exceeds what has been formally described.
