Baby Dolphin at Chicago’s Shedd Aquarium a Boy: The Pacific white-sided dolphin mother Piquet (pee-KEHT) probably knew already, but veterinarians at the Chicago’s Shedd Aquarium announced yesterday that her calf, born two weeks ago, is male. The pair made their debut swim for the paparazzi, but will remain off exhibit to the public for a few more weeks. The calf is nursing and has put on an extra five pounds since he was born on May 28; he now weighs about 30 lbs.
