A bizarrely-named little zoo in California is CuriOdyssey, and some facilities have names that are a bit confusing as it means that many people don't even realize that they are proper zoos. Arizona-Sonora Desert Museum, Rolling Hills Wildlife Adventure and California Living Museum are three such establishments that are all genuine zoos, but their names confuse anyone who is not a zoo enthusiast. There are many more examples of zoos without the word 'zoo' in their name.
One name that I do like is Riverbanks Zoo, which attracts more than a million visitors each year. It is located in Columbia, South Carolina, but due to the zoo's location on the banks of the Saluda River it is known as Riverbanks Zoo. That's pretty cool!
