The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
The southern giraffe (Giraffa giraffa), also known as two-horned giraffe, [1] is a species of giraffe native to Southern Africa. [2] However, the IUCN currently recognizes only one species of giraffe with nine subspecies. [3][4] Southern giraffes have rounded or blotched spots, some with star-like extensions on a light tan background, running ...
A newborn giraffe is 1.7–2 m (5 ft 7 in – 6 ft 7 in) tall. [47] Within a few hours of birth, the calf can run around and is almost indistinguishable from a one-week-old. However, for the first one to three weeks, it spends most of its time hiding, [109] its coat pattern providing camouflage. The ossicones, which have lain flat in the womb ...
Male okapi displaying his striking horizontal stripes. The okapi is a medium-sized giraffid, standing 1.5 m (4 ft 11 in) tall at the shoulder. Its average body length is about 2.5 m (8 ft 2 in) and its weight ranges from 200 to 350 kg (440 to 770 lb). [ 23 ] It has a long neck, and large and flexible ears.
Giraffidae. Giraffoidea is a superfamily that includes the families Climacoceratidae, Prolibytheriidae, and Giraffidae. The only extant members in the superfamily are the giraffes and okapi. The Climacoceratidae are also placed in the superfamily, but were originally placed within the family Palaeomerycidae.
The Reticulated giraffe is a herbivore feeding on leaves, shoots, and shrubs. Their up to 30 centimeter long blue tongue is used to strip the branches of acacia trees, their primary food source. [4] They spend most of their day feeding, roughly 13 hours/day, eating up to 34 kilograms of food per day. [12]
Ossicone. Ossicones are columnar or conical skin-covered bone structures on the heads of giraffes, male okapi, and some of their extinct relatives. Ossicones are distinguished from the superficially similar structures of horns and antlers by their unique development and a permanent covering of skin and fur.
Lyra (meaning "harp") is an extinct genus of giraffid artiodactyl ungulates from the Miocene Chinji Formation of Pakistan. The genus contains a single species, L. sherkana, known from a partial skull and fragmentary ossicones. Lyra may be a member of the subfamily Sivatheriinae. If this classification is correct, it would represent the oldest ...
