There are thirty-three species listed as extinct in the wild (EW) by the IUCN, meaning that they are only surviving through captive individuals, and they are extinct in the wild or their original range. Of these, many are kept in zoos. This classification is one of the main justifications for zoos, in fact, because without zoos, many of these species may have became fully extinct.
