果子貍是屬于靈貓科的小型哺乳動物。它遍及印度半島和東南亞。果子貍在所有種類的靈貓科動物中具有最廣泛的地理分布,并且能夠在各種類型的森林中生存。
果子貍具有細長的鼻子、小圓耳朵和細長的尾巴。長度在50到76厘米之間,而尾巴長度在50到64厘米之間,占整個身體長度的三分之二還多。它們的尾巴或身體都沒有條紋或斑點。果子貍的體重取決于性別和年齡,但成年果子貍的體重在3.6至5千克之間。
果子貍是夜間孤獨的捕食者,白天可能偶爾活動。它們部分是樹棲動物,通常躺在樹上和水源附近的“床”中睡覺。受到驚嚇時,果子貍會分泌物噴向捕食者,這些分泌物的功能與臭鼬的相似,可阻止其他捕食者。
果子貍是雜食動物,以老鼠和鳥類以及無花果、芒果、香蕉等水果和樹葉為食。他們還吃軟體動物、節(jié)肢動物、樹皮以及較小程度的蛇和青蛙。
果子貍在野外可以生存10年,在圈養(yǎng)中可以生存20年。
由于它在許多保護區(qū)出現(xiàn),在一定程度上可以改交棲息地,并且大量存在且分布廣泛它被世界自然保護聯(lián)盟列為“無?!蔽锓N。
