Nola Nola, a 41-year-old female northern white rhino, dies at the San Diego Zoo Safari Park. She was euthanized after her health took a turn for the worse. Nola was rescued from violent poaching in the southern savanna woodlands of Sudan and came to the park in 1989. Only three animals of this endangered species are known left in the world.
