Two incredibly rare Sumatran tiger cubs were born at a UK zoo, captured on covert cameras installed in the tiger enclosure. The births are a major boost for the conservation of the Critically-Endangered species, of which there are only 350 left in the wild. The newborns' gender is unknown, as zookeepers don't want to disturb the mother. The cubs' parents were paired up based on genetic make-up, age, and character, and their successful breeding is cause for celebration in the global conservation community.
