關於与「猎豹」名称相近或相同的条目,請見「猎豹 (消歧义)」。 獵豹(学名:Acinonyx jubatus),又稱印度豹,是貓科動物的一種,也是獵豹屬下唯一的存活物種,現在主要分布在非洲與西亞。與其它猫科动物不同,猎豹依靠速度来捕猎,而非偷袭或群体攻击。獵豹是陆上奔跑最快的动物,全速奔馳的獵豹,時速可以達100km以上。[2] 目录 1 体态 2 速度 3 分类 3.1 捕食 3.2 栖息地 4 经济价值 5 威脅 6 保育现况 7 参考文献 8 擴展閱讀 体态 虽然獵豹在大猫中体型较小,但不失其大猫的基本特質,健壯、胸膛壯闊但腰部纖细。擁有看來較小的头脑,短嘴,也有对高视力的眼睛,宽鼻,小巧的圆耳。超大号的鼻孔确保了猎豹能在高速奔跑时获得足够的氧气。 野生成年雄性獵豹体重為29至65千克,雌性猎豹为21至63千克,体長為112至135公分,尾巴可長至84公分。野生猎豹平均壽命为8到10年,超过12年的极为罕见。[3] 獵豹的黄色毛皮上的黑色斑点是實心圆,而花豹的斑点则是如花朵状的空心圆,美洲豹则是空心圆内还有個小圆點。 獵豹胸腹部為白色,尾巴则越靠近尾部條纹越明顯,而尾端则為全白色。 此外,獵豹臉上的斑點没有其他豹密集,并在口鼻兩侧有明顯的黑色泪线。 獵豹也有少數发生毛皮突变,有着更大、更密集的斑点,被称为“帝王獵豹”。过去曾经有被列为亚种的打算,但它们只是獵豹的突变体而已。野生的“帝王獵豹”目前只发现6次。 獵豹常被誤認為花豹,但除了体型比花豹小很多以外,最明顯的區別是獵豹從眼角開始,長長淚滴型的線條通過鼻子兩側直到嘴部。獵豹皮毛的顏色是淺褐色與約為0.78到1.85英寸的黑斑所構成,腹部是白色的,沒有斑點。它尾部末端有斑點彼此連接,形成4-6個暗色的環,尾部的末端的毛通常顔色較白。雄獵豹的體型比雌豹略大,頭部也稍大,但僅從外觀,很難分辨其性別。 剛出生的獵豹皮毛顔色很深,因此很不容易分辨混雜在其中的斑點。幾週後,沿背上開始長出灰黃色的厚毛,稱爲鬃毛。深色的毛,有助於獵豹寶寶隱藏在陰影裏。一般動物學家認爲鬃毛有幾個目的,除了抵擋太陽和大雨外,也是保護色,讓它們看來像是乾枯的野草。此外,也是種防禦性的偽裝,幼豹看來像是蜜獾,是種兇悍的小型獵食動物,大多數獵食者不願意招惹。約從第3個月開始,鬃毛會逐漸消退,但消退時間可能持續很長,有些鬣豹在兩歲後仍有帶有鬃毛。獵豹幼崽的鬃毛(鬣毛)也是獵豹名字的由来。 獵豹的種種生理特徵使它能適應高速,強有力的心臟、超大的肝、大而有力的動脈。它有小尺寸的頭,面部平坦、較短的面部肌肉,使一雙大眼睛的位置能提供最好的視力,較大的鼻孔和鼻腔。它的身體瘦長、有著輕而細長的腳掌和腿、高度進化的肌肉能為了加速,彼此同時運作,讓四肢有較大的伸展幅度。奔跑時四肢交替地集中和展開,它的臀和肩部環繞著高低起伏,很有伸縮性的脊椎旋轉。獵豹長而充

The cheetah was first scientifically described in the late 18th century. Four subspecies are recognised today that are native to Africa and central Iran. An African subspecies was introduced to India in 2022. It is now distributed mainly in small, fragmented populations in northwestern, eastern and southern Africa and central Iran. It lives in a variety of habitats such as savannahs in the Serengeti, arid mountain ranges in the Sahara, and hilly desert terrain.
