Photo of the Day #2: Female Okapi

Female Okapi

The photo I posted yesterday of a male Gerenuk (Litocranius walleri) has prompted some discussion about other long-necked artiodactyls, especially the living representatives of the family Giraffidae. Although the family once contained more members (like the oddly-ornamented Sivatherium), only the Giraffe (Giraffa camelopardalis) and the Okapi (Okapia johnstoni) are extant. Pictured above is a female Okapi at the Bronx Zoo, the distinction between the sexes being easily distinguished as the female lacks the skin-covered protrusions made of ossified cartilage known as “ossicones” that are prominent in the male.
