The term 'Cousins of Giraffes' refers to the okapis, which are six-letter mammals that are closely related to giraffes. They are found in the tropical rainforests of the Democratic Republic of Congo and have a similar appearance to giraffes, with long necks and legs. However, okapis have a much shorter neck than giraffes and their fur is striped like a zebra's. They are also much smaller than giraffes, standing at about five feet tall.
