  The okapi looks like a small-sized giraffe and has stry eh n, 7iieouc js33/t 1yuh9ek04d1fipes that resemble the zebra. It lives in the Ituri Forest in the Democratic Republic of the Congo. Okhneyedkfic9 jtys4/uu7 , e1i 130oh 3apis eat the leaves and buds of trees they can reach. They also graze on grass and ferns and eat fruit. Okapis tend to be solitary animals and the mother gives birth to one offspring which continues to be dependent on the mother’s milk for six months. When they are four to five years old, they are mature and can breed, but only with other okapis.

I. Okapi is a hybrid of a giraffe and a zebra
II. Okapi is an herbivore
III. Okapi is its own species
