二名法 Oryx dammahCretzschmar, 1827 彎角劍羚（Oryx dammah），又名白長角羚及白劍羚，是長角羚屬的一種，生活於整個北非地區。一般認為彎角劍羚已經在野外滅絕，但有報道稱小部份仍在尼日爾中部及乍德生存。[1] 目录 1 外觀 2 生態 3 保育 4 參考 5 外部連結外觀彎角劍羚。彎角劍羚肩高僅多於1米，重約200公斤。毛皮呈白色，胸部呈紅褐色，前額延至鼻端都有黑紋。牠的角幼長，像彎刀般向後彎曲，雄性及雌性的角都可長達1-1.25米。生態彎角劍羚棲息於草原及沙漠，專吃樹葉、草及水果。牠們的群族可達70頭，遷徙時會聚集幾千頭。牠們可以幾個星期不喝水也能生存，原因是牠們的腎臟可以阻止流失水份及控制體溫來避免流汗。保育彎角劍羚因其角而被獵殺至接近滅絕。牠們曾一度分佈在整個撒哈拉沙漠，但現時已被認為是野外滅絕，不過仍有未經證實的報道稱在乍德及尼日爾發現牠們的蹤跡。 1960年代曾有哺養彎曲劍羚的計劃。1996年統計有2145頭彎角劍羚在德克薩斯州及最少有1250頭在其他地方的動物園及公園生存。在突尼西亞有一個群族被保存了下來，並正計劃擴展至野外。[3] 參考 ^ 1.0 1.1 Oryx dammah.

in Bou-Hedma National Park, Tunisia Osteological specimen of a scimitar oryx in the Natural Science Research Laboratory's (NSRL) collection at the Museum of Texas Tech University. The scimitar oryx (Oryx dammah), also known as the scimitar-horned oryx and the Sahara oryx, is an Oryx species that was once widespread across North Africa and parts of West and Central Africa. In 2000, it was declared extinct in the wild on the IUCN Red List, but in 2023, it was downlisted to endangered, with a reintroduced population in Chad. This particular oryx is adapted to harsh desert conditions and can survive for months or even years without drinking water. A grazing animal, it derives most of its daily moisture intake from plants.

The decline of the scimitar oryx population began as a result of climate change during the Neolithic period, and later it was hunted extensively for its horns. Today, it is bred in captivity in special reserves in Tunisia, Morocco, and Senegal, and on private exotic animal ranches in the Texas Hill Country, United States. In 2016, a reintroduction program was launched, and currently a small herd has been successfully reintroduced in Chad.
