  The okapi looks like a small-sized giraffe and has stripes that resemble the 2ukf9r lv eekl9/7b-+bdpd wx/u26u pzebra. 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 fruitx2l2u 7 / eeuw 9+blp-rbvfk6d/9pkud. 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.
