Notes

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.

"Lucky" is believed to be a stage name used for all of the facility's walruses.
