Notes

The CITES Trade Database shows a single import of 19 or 22 walruses into China in 2014 — it is likely that this was the initial herd purchased by Chimelong.

Chimelong stated in April of 2015 that their walruses were between "1 and 3 years old", while a scientific article published in 2023 stated that the park's walruses were between 3 and 6 years old, assumed be to from the beginning of the study period in 2016. This places the herd's years of birth around 2010 to 2014. Additionally, the park stated in 2023 that the herd averaged 10 years of age — with the exception of the two individuals with known ages, Walrus Network generally considers Chimelong's wild-caught walruses to have been born around 2013.

 Chimelong is known to have housed 16 walruses — eight males and eight females — from 2016 to 2019. As of this writing on March 29th, 2025, thirteen walruses of Chimelong's initial herd of wild-caught pups are believed to still be alive; two individuals are believed to have passed in 2021 and 2022, while the identity of the third individual assumed to be no longer be present in the population is unknown at this time.

This park currently houses the largest herd of walruses in the world.
