Zoology: Bones

Femur from the Bone Clones® Siamang skeleton. Siamangs and other gibbons have the longest arms proportional to their body size of all the primates and have many skeletal adaptations to better enable their canopy lifestyle. Their thumb articulates uniquely among higher apes, extending from the wrist rather than the palm, which allows a much wider range of motion. They have the forward facing, wide-set eyes, short rostrum, and globular, larger brain case typical of most hominoids.

If you have a preference of right or left side, let us know. Otherwise, we will choose.
