Male Sumatran tiger cub Bandar is carried by Smithsonian National Zoo curator of great cats and bears Craig Saffoe (R) and biologist Leigh Pitsko (L) to perform in a swim test in a moat for the animal in Washington November 6, 2013. Two Sumatran tiger cubs born August 5 were tested to have the ability to keep their heads above water, navigate the shallow end of the moat, and possess the strength and ability to climb onto dry land.
