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 cyathophora is a unicellular marine haptophyte in the genus Chrysochromulina, order Prymnesiales, class Prymnesiophyceae. The specific epithet cyathophora derives from Greek meaning cup-bearing, describing a characteristic cup-shaped element — likely a scale morphology — visible under transmission electron microscopy. Such ultrastructural features are essential for species identification within Chrysochromulina, where species are otherwise morphologically similar at the light microscopy level. C. cyathophora is known from Norwegian coastal marine environments and has also been recorded from Brazilian waters, a distribution pattern shared by several Chrysochromulina species, suggesting either broad Atlantic dispersal or recurrent misidentification across these distant populations. The species occupies the nanoplankton size fraction and is adapted to life in the water column of coastal to open-ocean marine systems. Chrysochromulina species as a group are important contributors to marine primary production, particularly in oligotrophic environments where smaller phytoplankton dominate. They may also practice mixotrophy — ingesting bacteria and small prey alongside photosynthesis — providing metabolic flexibility in nutrient-limited conditions. The life cycle of Chrysochromulina typically involves asexual division, though sexual stages are poorly documented for most species. C. cyathophora has not been assessed under the IUCN Red List framework, carrying a conservation status of Not Evaluated, consistent with the broader treatment of marine microplankton taxa that present significant challenges for population-level assessment and threat evaluation.
