The little orangutan was frighteningly thin from malnourishment. He also had a bullet lodged in his shoulder - both indications that he'd been stolen from his mother in the wild under a hail of gunfire.
When Didik was finally brought to safety by the group International Animal Rescue (IAR), his heartbreak was unmistakable.
"For an animal like an orangutan, witnessing the death of its mother is a profoundly shocking experience," said IAR director Karmele Llano Sanchez in a release. "That is undoubtedly why Didik looks so sad and depressed."
