Notes and Information

This pup was rescued off the coast of Nome, Alaska after being discovered on a barge on June 14th. He was estimated to be two weeks old at the time.

His right eye was injured at the Alaska SeaLife Center, causing immediate blindness -- at some point while housed at SeaWorld Orlando, the eye was removed entirely.

Aku was transferred to SeaWorld Orlando two weeks prior to October 31st, 2017. His last day on public display at the SeaLife Center was on October 15th, though I'm not certain of the exact date that he was transferred.
