An ibex is any of several species of wild goat , distinguished by the male's large recurved horns, which are transversely ridged in front. Ibex are found in Eurasia, North Africa and East Africa. The name ibex comes from Latin, borrowed from Iberian or Aquitanian, akin to Old Spanish bezerro, 'bull', modern Spanish becerro, 'yearling'. Ranging in height from 70 to 110 centimetres (27–43 in) and weighing 90 to 120 kilograms (200–270 lb) for males, ibex can live up to 20 years. Three closely related varieties of goats found in the wild are not usually called ibex: the markhor, western tur, and eastern tur.

Capra is a genus of mammals, the goats, comprising ten species, including the markhor and several species known as ibexes. The domestic goat is a domesticated species derived from the bezoar ibex. Evidence of goat domestication dates back more than 8,500 years.
