外表特徵


中美貘的臉部、喉部有一塊乳白色印記,面頰上則各有一個暗點。身體的其他部分則為深褐色或灰褐色。是三種美洲貘中體型最大的,也是墨西哥到南美地區所見的最大陸生哺乳動物。


中美貘的體長通常為2米,身高1.1米,成年中美貘的體重在220-300公斤。與其他的貘一樣,它們的鼻子較長,可以靈活伸縮。前肢為四趾,後肢為三趾。



繁殖與壽命


中美貘的孕期大約為400天,每胎一般為一仔。幼仔的毛髮為紅褐色,帶有白色的斑點和條紋。這些印記在成長過程中逐漸褪去。


斷奶期一般為一年,過六到十二個月即達到性成熟。中美貘的壽命可達三十年以上。



行爲


中美貘每一時段都可能比較活躍。主要以樹葉和落下的果實為食,行走時的軌跡呈鋸齒狀。


一般居住在水的附近,尤其喜歡游泳和涉水。


中美貘是獨居動物,在繁殖季節也會聚集在一起。



棲息地


中美貘生活在中美墨西哥東南部、伯利兹、危地馬拉、洪都拉斯、哥斯達黎加、尼加拉瓜和巴拿馬等國的茂密叢林中。甚至可能呆在海拔3,350米的高地。



保育情況




中美貘


根據世界自然保护联盟提供的資料,中美貘被列爲瀕危動物,其主要面臨的威脅是棲息林地的減少和偷獵。
