SAN ANTONIO (AP) - Officials at the San Antonio Zoo say the recent birth of two Sumatran tiger cubs is significant because the species is critically endangered and only about 400 survive in the wild.
Zoo staff is keeping a distance from the cubs so as not to disrupt interactions with their mother, Kemala (kee-MAH-la). Zoo Executive Director Steve McCusker says the cubs each weigh under a pound and are "absolutely helpless."
The cubs were born Sunday and won't be available for public viewing for several months. Their sex is not clear yet and they haven't been named. McCusker says the staff is relieved because Kemala, a first-time mom, is nursing the cubs rather than abandoning them.
Sumatrans are a smaller species of tiger whose native habitat is the island of Sumatra in Indonesia.
