The Zoo hasn't said anything lately, but I believe Kalluk is spending most of his time on the other side; I don't know if this is the Zoo's idea or his. Right now, it is his sister, Tatqik, who is front and center of the camera, she is the great carrot lover, you can see how much pleasure she gets out of eating those carrots. Chinook has a bigger stomach and a bigger caboose, and her eyes are more slanted. I expect that she is on the other side, as well, unless they have placed her in separate quarters in case of pregnancy. Tatqik is not quite as entertaining as the big guy, but she is fun to watch in the water as she thinks of all kinds of games to play on her own.
