A beluga swims with her baby at Changsha Sea World in Changsha, capital of central China's Hunan Province, Nov. 20, 2016. A female beluga, imported from Russia with her "mate" in 2010 and housed at the Changsha Sea World for display, successfully gave birth to a baby on Sept. 22. It is rare that a beluga baby is born and survives in artificial breeding. The 2-month-old baby now is roughly 100kg in weight and 1.7 meters in length. (Xinhua/Li Ga)
