Okapis

The okapi, a forest mammal of central Africa, has presented zoologists with a number of difficult questions since they first learned of its existence in 1900. The first was how to classify it. Because it was horse like in dimension, and bore patches of striped hide similar to a zebra’s (a relative family is confirmed by its skin-covered horns (in males), two-lobed canine teeth, and long prehensile tongue.

The next question was the size of the okapi population. Because okapis were infrequently captured by hunters, some zoologists believed that they were rare; however, others theorized that their habits simply kept them out of sight. It was not until 1985, when zoologists started tracking okapis by affixing collars equipped with radio is concentrated in an extremely limited chain of forestland in northeastern central Africa, surrounded by savanna.

One reason for their seeming scarcity is that their coloration allows okapis to camouflage themselves even at close range. Another is that okapis do not travel in groups or with other large forest mammals, and neither frequent open riverbanks nor forage at the borders of clearings, choosing instead to keep to the and because of the distribution of their food, okapis engage in individual rather than congregated foraging.

But other questions about okapi behavior arise. Why for example, do they prefer to remain within forested areas when many of their favorite plants are found in the open border between forest and savanna? One possibility is that this is a defense against predators; another is that the okapi was pushed into and that they continue to respect those borders even though available forestland has long since expanded.
