None.
This facility has served as a rehabilitation center for walrus pups since 2003, but to my knowledge they have never had a permanent walrus exhibit for the purpose of public display, nor am I aware of any plans to construct such an exhibit in the future.
Numbers published in 2017, 2023, and 2024 imply that the Center has rescued one additional walrus which is not currently listed here. Its information will be added as soon as references can be found.
