Female Bornean Orangutan Skull by Bone Clones

The orangutan, Asia's sole great ape, typically lives alone, except for the enduring bond between mothers and their offspring. Females reproduce every eight years, nurturing their young until they're six, then teaching them independence for a few more years. Females are half the size of males. This arboreal giant inhabits the forest canopy, rarely venturing to the ground, and moves with curled hands and feet, unlike African great apes that knuckle-walk.
