Three-week-old White-Cheeked Gibbon baby 'Walli' drinks bottled milk in the arms of surrogate mother Christina Schneider at the Schwerin Zoo in Germany yesterday, November 25th. The baby was not accepted by its mother and therefore has to be raised by hand. 'Walli' has to be fed every two hours. The hand raising will take about six months.
