Sivuqaq (walrus)

Sivuqaq, also known as Jocko, was a Pacific walrus at the Six Flags Discovery Kingdom in Vallejo California. He was 18 years old as of 2013.[3] He has been the subject of a number of television and radio programmes,[4][5] most recently focussing on the steps that his keepers have been taking to encourage him to father calves, which has in the past proved difficult for walruses in captivity. He was one of a number of walrus calves brought to Vallejo in 1994; the three other surviving walruses are the females Qiluk, Uquq, and Siku. They were orphaned as the result of hunting near the city of Gambell, Alaska,[6] from whose Yupik name Sivuqaq takes his name. He died in 2015.[7]
