Notes and Information

This walrus was six months old at capture and spent a month housed at the Moscow Zoo before being transferred, alongside another individual, to Izu-Mito Sea Paradise. The pair were then transferred to Yokohama Hakkeijima Sea Paradise, where they were confirmed alive until at least April 28th, 1997.

There is a significant possibility that this walrus and its herdmate are in fact Seita and Uchi, although I cannot be certain at this time.
