二名法 Equus grevyiOustalet, 1882 分布圖 細紋斑馬（學名：Equus grevyi）又名格氏斑馬、狹紋斑馬，是三种斑马中体型最大的一种。分布于非洲的肯尼亚和埃塞俄比亚[2]。与其他斑马相比，细纹斑马的个子较高，耳较大，斑纹则更加狭窄，差别较为明显，相对而言，细纹斑马与驴的亲缘关系较接近。细纹斑马与平原斑馬（普通斑馬）的分布范围有所重叠。 目录 1 特征 2 食性 3 行为与繁殖 4 保護及現況 5 参考文獻 5.1 延伸閱讀 6 外部链接 特征 动物园里的细纹斑马 细纹斑马是所有马科动物中最大的一种，体长为2.5-3米，尾长38-75厘米，肩高1.25-1.6米。体重为350-450千克。斑纹及间距都十分窄小，一直到蹄部都有，颈部较宽，下腹部和尾根部没有斑纹。耳很大，呈圆锥形。头部长而窄，形状十分接近骡。鬃毛较长并竖立。 食性 主要以草为食，同时也吃水果、灌木和树皮。每天60%以上的时间都被用于进食。 行为与繁殖 细纹斑马在行为上与驴有很多相似之处。比如，成年细纹斑马会在短期内组成小规模的种群。成年公斑马以独居为主，其领地范围为2-12 km²，比野驴的范围小些。 肯尼亚的母细纹斑马 领地主要由粪便来划定，母细纹斑马只与本领地内的公斑马交配。这种社会结构适应于细纹斑马生活的干燥的灌木林和平原地区。细纹斑马通过打斗来决定领地和交配权。 细纹斑马的孕期为350-400天，每胎产一仔。 保護及現況 目前的状况为濒危，面临的主要威胁来自偷猎。细纹斑马的皮毛可以在市场上卖到极高的价格。同时栖息地的破坏、人类的干扰以及其他动物的竞争，也是细纹斑马数量减少的重要因素。目前全世界野外生存的细纹斑马大约还有2500头左右。[1][3]不过，全世界动物园中的斑马很多都是细纹斑马。 参考文獻 ^ 1.0 1.1 Equus grevyi.

Grévy's zebra (Equus grevyi), also known commonly as the imperial zebra, is the largest living species of wild equid and the most threatened of the three species of zebras, the other two being the plains zebra and the mountain zebra. Named after French president Jules Grévy, it is found in parts of Kenya and Ethiopia. Superficially, Grévy's zebra's physical features can help to identify it from the other zebra species; its overall appearance is slightly closer to that of a mule and donkey, compared to the more "equine" (horse) appearance of the plains and mountain zebras. Compared to other zebra species, Grévy's zebra is the tallest; it has mule-like, larger ears, and has the tightest stripes of all zebras. It has a distinctively erect mane, and a more slender snout.
Grévy's zebra lives in semi-arid savanna, where it feeds on grasses, legumes, and browse, such as acacia; it can survive up to five days without water. It differs from the other zebra species in that it does not live in a harem, and it maintains few long-lasting social bonds. Stallion territoriality and mother–foal relationships form the basis of the social system of the Grévy's zebra. Despite a handful of zoos and animal parks around the world having had successful captive-breeding programs, in its native home this zebra is listed by the IUCN as endangered. Its population has declined from 15,000 to 2,000 since the 1970s. In 2016, the population was reported to be "stable"; however, as of 2020, the wild numbers are still estimated at only around 2,250 animals, in part due to anthrax outbreaks in eastern Africa.
