The pileated gibbon[1] (Hylobates pileatus) is a primate in the gibbon family, Hylobatidae.
- Pileated gibbons are small apes with rounded heads, shaggy fur, long torsos and forearms, and no tails.
- Although the two sexes are similar in size and weight, sexual dimorphism is visible in their coloration: males have short black fur with white hands, feet, and headbands, while females range in color from pale yellow to silvery gray with black head and belly.
- This color difference is called sexual dichromatism. Both sexes typically have a white circular band around the crown and sides of the head, hence the name “pileated“, meaning “capped“.
- Their faces are bare and have dark pigmentation. They have an opposable thumb and an opposable big toe that allows them to grasp and carry objects with their hands and feet.
