Inuk, a 15-year-old beluga weighing 2,600 pounds, arrived late Sunday from an aquarium in Tacoma, Washington, for a breeding program designed to provide competition for Shedd's resident male, Naluark, an 11-year-old weighing 1,500 pounds. Naluark had sex numerous times with three females at the aquarium during last year's spring breeding season, but none became pregnant. The Shedd Aquarium kept two female whales and sent a younger female to Washington in exchange for Inuk and a female, Mauyak, which means "Soft Snow." For now, Inuk (which means "Old Man" in the Inuit language) and Mauyak were checking out their new companions through a gate between adjoining pools at the aquarium's Oceanarium exhibit. The whales should be swimming together within a few days. Marine mammal experts believe competition increases the sexual potency of male beluga whales, and may have resulted in the six beluga whale births in captivity.
