Now that she's grown larger, the Cincinnati Zoo says she's spending more time in the adult pools and getting comfortable with deeper water:
"She porpoises, pushing off the bottom like a torpedo, up and down across the length of both pools and attempts water acrobatics. She has also figured out that she can keep her nostrils above water if she stands on her back legs, so you can see her walking upright at times."
Right now, she's in a pool about 3 feet deep; by the end of the week, it'll be at 4 feet. Her caretakers will keep raising the water until they think she's ready to take a tip in the big outdoor pool, which is 8 to 9 feet deep.
