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。

川秋沙〔普通秋沙〕

<em>Mergus merganser</em>, the common merganser or goosander, is a large diving duck in the family Anatidae, broadly distributed across Europe and North America. It is classified as Least Concern on the IUCN Red List. This species is capable of aerial, terrestrial, and aquatic locomotion, but is most specialized for underwater pursuit of prey. The common merganser is typically piscivorous, diving in clear, fast-flowing rivers and lakes to catch fish using its serrated bill, which provides a firm grip on slippery prey. Males display striking breeding plumage with a dark green head, white body, and red bill, while females are grey with a rusty-brown head and crested nape. The species nests in tree cavities, cliff ledges, and artificial nest boxes near freshwater habitats. It requires clean, well-oxygenated rivers and lakes for foraging, making it sensitive to water quality degradation and overfishing of prey species. Common mergansers are migratory in northern parts of their range, moving to coastal and ice-free inland waters during winter months.
