Four African lion cubs born to Shera on March 2 had their swim reliability test Tuesday morning.
All lion cubs at the Smithsonian's National Zoo must take a swim test, carefully monitored by the animal care team, before going on exhibit.
As part of the test they must prove that they can swim to land and pull themselves out of the water. All of the cubs passed. They are now one step closer to going on exhibit in a few weeks with their aunts and half siblings.
Two other lion cubs, born in January, recently passed their swim test and will make their public debut Friday at the zoo.
