Monterey Bay Aquarium
At least three exhibitions have been devoted entirely to displaying jellyfish. In 1989, the aquarium's second temporary exhibition, titled "Living Treasures of the Pacific", included three jellyfish tanks following the successful display of one tank of moon jellies four years earlier in 1985. In 1992, the first temporary exhibition for jellyfish opened, called "Planet of the Jellies", the success of which prompted a permanent jellyfish gallery within the Open Sea wing in 1996. Within 20 years of opening Planet of the Jellies, the aquarium created two more temporary exhibitions centered on jellyfish. The final one of the three exhibitions opened in 2012, and displayed around 16 species of jellyfish from around the world in "a psychedelic theme from the 1960s". Staff members attribute the organization’s fascination with jellyfish to their visual appeal, primitive biology, and reputed calming effect on visitors.
