Between 1955 and the transfer of management to the Cleveland Metroparks in 1975, the Zoo experienced rapid expansion despite setbacks due to flooding: the Zoo 's reptile collection and several other buildings were lost when Big Creek overflowed in January 1959. Although the Zoo had recovered by 1962, it would not have another permanent reptile collection until the opening of the RainForest thirty years later. Construction began on the Primate & Cat Building in 1975 (the Aquatics section would be added in 1985), later followed by the RainForest in 1992, Wolf Wilderness in 1997, Australian Adventure in 2000, and the Sarah Allison Steffee Center for Zoological Medicine in 2004. The Zoo 's official website states that it currently has 3,000 animal residents representing more than 600 different species.
