Two black monkeys are observed in an indoor enclosure through a reflective glass barrier. A monkey on the left is seated on a patterned tiled floor, facing right, and is actively grooming the back and rump area of a second, partially visible monkey standing to its right. The grooming monkey uses its hands to pick at the fur of the other. The background features a solid green wall with a light-colored leaf stencil and a large, dark tree branch on the left. The monkeys have dark fur, some white facial markings, and a distinct crest of hair on their heads.
