in both sexes. Males are much more robust than females. Their coats consist of a long, reddish-brown hair, with a dark stripe running down the back. Males possess the most impressive manes which extend right down the back and grow longer, based on the age. In the oldest males the muzzle darkens to black and the eye stripes also darken. As with most
mountain goats and sheep, they have rubber-like hooves to provide balance and traction on the steep, rocky slopes.

Taxonomy and etymology
The species was first described from specimens obtained by Dr. A.S.G. Jayakar from Jebel Taw and originally given the name ''Hemitragus jayakari''. It was separated into the newly created genus ''Arabitragus'' on the basis of a study on the molecular phylogeny of the group in 2005.
The genus name ''Arabitragus'' is derived from the

s becoming feral and foraging in places that were once strictly the tahr's home. Habitat degradation is also another major threat, due to construction of roads, buildings, and mineral extraction. Also, poaching often occurs when the animals descend down from the mountains for water.
Conservation
In 1973, efforts were planned to protect the Arabian tahr, and in 1975, it was granted in the Hajar Mountains. In 1980, a captive-breeding program was set up at the Omani Mammal Breeding Center to reintroduce captive-bred individuals back into the wild. Three institutions are now involved, one in Oman and two in the United Arab Emirates, but many people seem to be unaware about the tahr's grave situations, leading to other conservation initiatives to focus on the publicity and educational campaigns to raise the animals' profile. In April 2009, the
