Rhino
The rhinoceros is a large, primitive-looking mammal that in fact dates from the Miocene era millions of years ago.
In recent decades rhinos have been relentlessly hunted to the point of near extinction.
Since 1970 the world rhino population has declined by 90 percent, with five species remaining in the world today, all of which are endangered.
The white or square-lipped rhino is one of two rhino species in Africa.
It in turn occurs as two subspecies, the southern and the northern.
The southern dwindled almost to extinction in the early 20th century, but was protected on farms and reserves, enabling it to increase enough to be reintroduced.
The northern white rhino has recovered in Democratic Republic of Congo from about 15 in 1984 to about 30 in the late 1990s.
This population, however, has recently been severely threatened by political conflict and instability.
The white rhino's name derives from the Dutch "weit," meaning wide, a reference to its wide, square muzzle adapted for grazing.
The white rhino, which is actually gray, has a pronounced hump on the neck and a long face.
The black, or hooked-lipped, rhino, along with all other rhino species, is an odd-toed ungulate (three toes on each foot).
It has a thick, hairless, gray hide.
Both the black and white rhino have two horns, the longer of which sits at the front of the nose.
