It was a big day at the L.A. Zoo yesterday, when the endangered Sumatran Tiger Cubs made their debut. Mom tiger, named Joanne, kept a close watch on her three 3-month-old cubs—Nelson, Cathy and Debbie—who were curious about everything.
There are fewer than 350 Sumatran tigers in the wild, and that number continues to drop. Scientists estimate that this species could be extinct in its native Sumatra by 2020, unless measures are taken to protect and preserve it.
