This photo taken on June 3, 2017 shows a black lamb born to a white sheep at the Chiba Zoological Park in Chiba City outside Tokyo. The 42-centimetre-tall baby male was born on May 21. According to his keeper, the lamb is a Corriedale, a breed whose colour is basically white, but in rare cases a black sheep is born with a genetic mutation. (Photo/Agencies)
