the female killer whale at Marine World Africa in Vallejo, California died on October 29, 1997.
Yaka was probably close to 30 years old, some 20 years below the average lifespan of her female relatives in the wild. The cause of her death is probably pneumonia. Pneumonia is one of the most common causes of death among cetaceans in captivity.
Yaka, a Pacific Northwest killer whale, came to Marine World Africa in
December 1969 together with male Nepo. Nepo died in July 1980. Since November 1980 she was accompanied by Icelandic female killer whale Vigga, who will now be the only orca at Marine World Africa.
Yaka was a member of the A5 pod, as is Corky at SeaWorld California.
Corky and Lolita at the Miami Seaquarium are now the last surviving orcas captured in the Pacific Northwest. For both whales there are campaigns running for a rehabilitation in their natural waters and a possible release. So far the captive industry has refused to talk about it.
