A zoo official says Friday, Dec. 19, 2014, efforts will continue to save the critically endangered northern white rhinos from extinction. After a recent death of two, there are only five of northern white rhinos left: one at the San Diego Zoo Safari Park, one at the Dvur Kralove Zoo in the Czech Republic and three in a preserve in Kenya.
