Bonobo o chimpazé pigmeu

Three weeks old Bonobo baby Luebo is ruffled by his mother Lisala in a zoo in Wuppertal, Germany, Friday, April 7, 2006. There are only 160 pygmy chimpanzees in zoos in Europe and North America. In their habitat in central Africa, Bonobos are threatened with extinction, being thought to be the rarest of all the great ape species. (AP Photo/Martin Meissner)
