GIBBONS ARE APES, NOT MONKEYS. THEY ARE ONE OF THE FEW PRIMATES THAT SING, AND THEIR DUETS CAN LAST UP TO HALF AN HOUR AT A TIME!

They use their strong hook-shaped hands and long arms to move by swinging, hand over hand, from branch to branch. Their coats range from pale cream to black; they have white markings on their faces, hands, and feet. Gibbons primarily monogamous and use their singing to establish territory.
