♀ Maili (death 2017-Apr)
? Doudou (unknown ≥ 2011)
On September 25, 2010 Tianjin received at least one walrus from Dalian Laohutan Ocean Park. In an article published on August 4th, 2011, Tianjin is said to have two walruses; Doudou and Maili. I presume that these animals arrived together from the September 2010 shipment.
This facility currently houses a minimum of four walruses; a male and female pair housed on exhibit with South American sea lions, as well as two performing bulls.
Lucky, formerly listed as the name of one of the two performing bulls (specifically the individual with a single visible tusk), is now believed to be a stage name used for all of the facility's walruses.
