Giraffidae (Sub-family of Artiodactyla)
Giraffidae, from Arabic زَرَافَة (zarāfa, “giraffe”), in reference to the fact that all the members of this family are giraffe-related.
Common names of members
Girraffe, okapi.
Distribution
Sub-Saharan Africa.
Size
They are large animals, varying in size from 1.5 m tall and 200–350 kg in weight to 4.3–5.7m tall and 1,192 kg.
Morphology
They feature long necks and legs, a long, prehensile tongue that is black in color, lobed canine teeth, coats with patterns that serve as camouflage, and a back that slopes in the direction of the back. Some have ossicones, a pair of horns covered with skin.
Ecology & Habitat
Savannas and rainforests.
Diet
Strictly herbivores, their eating patterns are correlated with body size; larger species graze on high-fiber flora in wide grasslands, whilst smaller animals forage in dense, enclosed environments. The main source of food is grasses and leaves.
Reproduction
They are polygamous: a few males mate with the fertile females. Due to the dispersion of oestrous females throughout the landscape, reproductive adult males devise a strategy of roving among female groups in search of opportunities for mating, engaging in hormone-induced rutting behavior roughly every two weeks.
