Capra ibex Linnaeus, 1758, is a bovid commonly called the Alpine ibex that is sexually dimorphic. Body mass and scimitar-shaped horns are more than twice as large in males as in females. There are 8 extant species in the genus Capra. C. ibex is endemic to the Alpine Range of central Europe, was eliminated throughout its range except the Italian Alps, and has since been translocated to the Alps of Austria, France, Germany, Italy, Slovenia, and Switzerland at elevations of 1,600–3,200 m. Habitat selection by C. ibex is mainly influenced by the gradient and extension of mountain slopes. It is not a species of special conservation concern and has increased to <20,000 individuals.
