Over the next six years, Ramu matured into a bull Orca and began to outgrow the relatively small tank at the safari park.
In October 1976, Ramu was sold to SeaWorld San Diego in a swap that saw two female Orcas (named Winnie and Hoi Wai) move in the other direction.
As a fully grown male, Winston dwarfed even his pool mates, his size distinguishing him almost as much as his dorsal fin, which flopped over to his left hand side and made him instantly recognizable to visitors to the park.
Katina was the first to give birth, on September 26, 1985, to a healthy young female Orca named Kalina (the first of the 'Baby Shamu' generation of whale calves).
In 2004, Keet had his first offspring, a female called Kalia, the first great grandbaby Shamu, making Winston a great-grandfather.
