Sivuqaq, also known as Jocko, was a Pacific walrus at the Six Flags Discovery Kingdom in Vallejo, California. [3] He was the subject of several television and radio programmes,. [4] [5] Some of which focussed on the steps his keepers took to encourage him to mate successfully. 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,. [6] Gambell's name in Yupik, "Sivuqaq", inspired his name. He died in 2015. [7]
Sivuqaq was the subject of research on the vocalisation, [8] reproductive habits, [1] and cognition [9] of walruses.
Sivuqaq appeared as Jocko in the 2004 film 50 First Dates . [10]
