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。

Coelosphaerium kuetzingianum is a colonial planktonic cyanobacterium in the family Merismopediaceae, named in honour of the nineteenth-century German phycologist Friedrich Traugott Kützing, who made foundational contributions to the study of algae and cyanobacteria. The species forms spherical to globular mucilaginous colonies with cells arranged near the periphery of a clear gelatinous matrix—the characteristic architecture of the genus. Individual cells are small, typically 2–5 micrometres in diameter, and possess gas vesicles that confer buoyancy regulation, enabling the organism to position itself advantageously in stratified water columns. Coelosphaerium kuetzingianum has been recorded from freshwater lakes, reservoirs, and ponds across temperate northern Europe, including Denmark, Norway, and Sweden, as well as from Taiwan, indicating a broad latitudinal tolerance. Its occurrence in both boreal and subtropical settings suggests morphological plasticity or the presence of distinct ecotypes within the species concept. As with other members of the genus, it participates in aquatic food webs as a primary producer and is consumed by filter-feeding zooplankton such as cladocerans and rotifers. Eutrophication resulting from agricultural nutrient loading can stimulate cyanobacterial growth in affected water bodies. No IUCN conservation assessment has been undertaken for this planktonic cyanobacterium.
