Sivuqaq (walrus)

Sivuqaq, also known as Jocko, was a Pacific walrus at the Six Flags Discovery Kingdom in Vallejo, California. He was the subject of several television and radio programmes,.

He was one of a number of walrus calves brought to Vallejo in 1994; the three others were the females Qiluk, Uquq, and Siku. They were orphaned as the result of hunting near the city of Gambell, Alaska,. Gambell's name in Yupik "Sivuqaq" inspired his name. He died in 2015.
