Notes

Marineland's walrus herd began in 1961 with a group of four animals (Farouk, Petula, Priscilla, and Woofy). Though the park held a public naming contest for the animals in February of 1962 (which was won by 7-year-old Susan Riley, who submitted the names "Willy, Wally, Winnie, and Winkie"), the animals had already been named by their care team at that point, and their original names continued to be used. 

Although most accounts claim that these four individuals survived to maturity and remained at the park, it is known that Priscilla died in 1968. Additionally, one scientific article states that Marineland housed two breeding pairs -- Farouk and Petula collected in 1961, and Woofy and Priscilla collected in 1967 -- implying that Woofy from the original group either no longer existed in the park, or simply never produced offspring there. I do not know whether Woofy died at Marineland or was transferred away, nor do I know at what point either of those events may have taken place. To the best of my knowledge all four original animals were alive into early 1968 (a news article on Priscilla's death published in May of that year claims that she was the first to pass away), and I do know that the original Woofy was present at the park at least until 1966 -- a year before his namesake was captured, and two years before he arrived at Marineland.

It was mistakenly reported that in 1969 that Marineland of the Pacific had donated two "walruses" named Dicki and Ticki to the Chapultepec Zoo, which arrived in Mexico on March 27th. These individuals were instead Northern elephant seals, captured by Marineland two months prior off the coast of Mexico.
