IBEX
An ibex is any of several species of wild mountain 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 27 to 43 inches and weighing 200 to 270 pounds, ibex can live 20 years. Two closely related varieties of goats found in the wild are not usually called ibex: the markhor and the feral goat. Male ibex are commonly larger and heavier than females, and their most noticeable difference is the large size of their horns. Females grow a pair of smaller, thinner horns which develop considerably more slowly than the males'. The ibex's horns appear at birth and continue to grow through the rest of its life.
