Muellers gbbon

At the Cincinnati Zoo.

Mueller’s gibbons (Hylobates muelleri) feast on scattered patches of ripe fruit. Traveling over half a mile a day, they help regenerate the forest as they disperse seeds they have eaten. Unfortunately, this natural process of growth cannot keep up with the rate at which the gibbon’s forests are being destroyed.
