  The okapi looks like a small-s bo:p.znwlygz,4x5 /x8 uucb 5ized giraffe and has stripes that resemble the zebra. It lives in the Ituri Forest in the Democratic Republic of the Congo. Okapis 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 arenb8x:lzwcbp4u./ ouxg,5 y5 z mature and can breed, but only with other okapis.
