The okapi exhibits sexual dimorphism, with females 4.2 cm (1.7 in) taller on average, slightly redder, and lacking prominent ossicones, instead possessing hair whorls. [29] [30] The okapi shows several adaptations to its tropical habitat. The large number of rod cells in the retina facilitate night vision, and an efficient olfactory system is ...
The Okapi Wildlife Reserve – an area 13,700 square kilometers, about one-fifth of the Ituri Forest – was created with the help of the Okapi Wildlife Project in 1992. The project continues to support the reserve by training and equipping wildlife guards and by providing assistance to improve the lives of neighboring communities. [1]
The Okapi Wildlife Reserve (French: Réserve de faune à okapis) is a wildlife reserve in the Ituri Forest in the north-east of the Democratic Republic of the Congo, near the borders with South Sudan and Uganda. [3] At approximately 14,000 km 2, it covers approximately one-fifth of the area of the forest.
Palaeotragus ("ancient goat") is a genus of very large, primitive, okapi-like giraffids from the Miocene to Early Pleistocene of Africa and Eurasia.. Palaeotragus primaevus is the older species, being found in early to mid-Miocene strata, while P. germaini is found in Late Miocene strata.
In okapi, the male's ossicones are smaller in proportion to the head, and taper towards their tips, forming a sharper point than the comparatively blunt giraffe ossicone. Whereas female giraffes have reduced ossicones, female okapi lack ossicones entirely. The morphology of ossicones in the extinct relatives of giraffes and okapi varies widely.
Of the proteins in giraffe and okapi genes, 19.4% are identical. The divergence of giraffe and okapi lineages dates to around 11.5 mya. A small group of regulatory genes in the giraffe appears responsible for the animal's height and associated circulatory adaptations. [14] [15]
The scientific name of the blackbuck Antilope cervicapra stems from the Latin word antalopus ("horned animal"). [2] [3] The specific name cervicapra is composed of the Latin words cervus ("deer") and capra ("she-goat").
There is little advantage in adaptations that permit successful competition with other organisms, because the environment is likely to change again. Among the traits that are thought to characterize r -selection are high fecundity , small body size , early maturity onset, short generation time , and the ability to disperse offspring widely.
