Siamang Gibbon Articulated Hand Replica

Description

Siamang gibbon articulated hand replica measures 3.0 x 3.0 x 1.5 inches. Symphalangus syndactylus hand is museum-quality polyurethane resin cast from the California Academy of Sciences specimen. 1:1 scale. Made in USA.

This specimen demonstrates a significant elongation of the metacarpals and proximal phalanges. Accordingly, these bones increase the overall surface for gripping large branches.

The siamang hand possesses a specialized arrangement of the carpal bones. Specifically, this structure permits the hand to act as a pivot point during high-speed swings.

This skeletal adaptation reduces the mechanical strain on the forearm while maintaining a secure hold. Additionally, the distal phalanges also exhibit broadened tips. These tips support the fleshy pads used for tactile feedback while navigating the highest canopy reaches. Thus, these intricate bone details confirm the species’ status as a master of aerial movement.

To create a compelling display, collectors and curators often pair this specimen with the siamang gibbon male skull replica, the western hoolock gibbon skull replica. This specific grouping allows educational examinations for students and collectors alike. Introducing the white-handed gibbon skull replica completes the set, illustrating the refined skeletal shifts these primates developed for survival in diverse Asian rainforest environments.
