Zoo Basel was the scene of high drama in late December when Spider Monkey mom, Quilimari, suffered complications during child birth. Too weak to care for her newborn, she was taken into the zoo veterinarians' care but the prospects for her tiny baby were tenuous, as baby monkeys without natural mothers have high mortality rates.
Luckily for all, the baby's young-adult older sister, Dicha, immediately jumped in, scooping up the baby and, surprisingly, nursing it like her own. How Dicha was able to nurse a baby immediately upon birth, while not pregnant or a recent mother herself, is a mystery.
When the mother was returned a few days later, the daughter dutifully returned her little brother to her mother's care. Now a month later, all is well. - Heroic older sis looking concerned below -
