Oryx (/ ˈ ɒr ɪ k s / ORR-iks) is a genus consisting of four large antelope species called oryxes.Their pelage is pale with contrasting dark markings in the face and on the legs, and their long horns are almost straight.
They have muscular necks and shoulders, and their legs have white 'socks' with a black patch on the front of both the front legs, and both sexes have long, straight horns. Comparably, the East African oryx lacks a dark patch at the base of the tail, has less black on the legs (none on the hindlegs), and less black on the lower flanks.
The Arabian oryx' coat is an almost luminous white, the undersides and legs are brown, and black stripes occur where the head meets the neck, on the forehead, on the nose, and going from the horn down across the eye to the mouth. Both sexes have long, straight or slightly curved, ringed horns which are 0.61–1.49 m (2–4.9 ft).
The scimitar oryx is a straight-horned antelope that stands just over 1 m (3.3 ft) at the shoulder. The males weigh 140–210 kg (310–460 lb) and the females 91–140 kg (201–309 lb). [10] The body measures 140–240 cm (55–94 in) from the head to the base of the tail. The tail is 45–60 cm (18–24 in) long and ends with a tuft.
There is a short mane of brownish hair, as well as tufts of black hair above the hooves, at the end of the tail, and on the ears. It is from the last feature, unique among the various kinds of oryx, that the subspecies gains its common name. [4] The horns are 76 to 81 cm (30 to 32 in) long, and almost straight, with only a slight backwards curve.
Other points of difference include a longer, broader, and rigid bridge to the nose and more muscular cheeks in springbok, and differences in the structure of the horns. [12] Both sexes have black horns, about 35–50 cm (14–20 in) long, that are straight at the base and then curve backward.
True horns are found mainly among: Ruminant artiodactyls. Antilocapridae ; Bovidae (cattle, goats, antelopes etc.). Giraffidae: Giraffids have a pair of skin covered bony bumps on their heads, called ossicones. Cervidae: Most deer have antlers, which are not true horns due to lacking a bone core and made of keratin.
[28] [29] [21] [27] These hybrid animals have a diploid number 2n = 33 and all known cases produced female animals, which had developed horns like female bongos while their stripping pattern was intermediate between bongos and sitatungas with an overall orange coloring.
