I want to say until 1992 or so - I remember being on a field trip in elementary school and being so sad when I realized that they didn’t have them anymore
Yeah, January 1992 is when three belugas were transfered to Sea World Texas for long term breeding loan. I believe there may be one of those whales still alive, but I'd have to check.
Belugas were originally housed as an alternative to dolphins in the Central Tray (now Blacktip Reef) off and on starting in 1983. All four whales then moved to the newly opened Marine Mammal Pavilion in 1990 and did quite well. After a dolphin rammed one of the whales during a show and killed it in December 1991, the decision was made to separate the two species and focus only on dolphins.
