I think the most underrated zoo is the Greensboro Science Center. I know what you might be thinking, how can a science center even be classified as a zoo!! But the Greensboro Science Center is not only an AZA accredited zoo but also a AZA accredited aquarium (As well as an AAM accredited museum). In the Aquarium you can find Fishing Cats, Asian Small-clawed Otters, African Penguins, Sandbar, Blacktip, Bamboo, and Epaulette Sharks, Cownose, Spotted Eagle, and Southern Stingrays, Green Moray Eels, Garden Eels, Pufferfish, Moon and Upside-down Jellies, Lionfish, Deep Sea Isopods, Seahorses, Mantis Shrimp, Tons of Reef communities, Golden Lion Tamarins, Ti-ti Monkeys, a Caiman Lizard, a Green Anaconda, and lots of Amazonian fish. In the museum part, you can find most the animals you would expect to see at a science center (Your herps and inverts, including a 100 year Alligator Snapping Turtle). In the Zoo you will find Meerkats, Aldabra Tortoises, a Nile Crocodile, a Komodo Dragon, a discovery house (Housing the other animals you would expect to find. Like your Ferrets, Guinea Pigs etc.), Red Pandas, Javan Gibbons (One of only 3 places in the US were you can find this species), Ring-tailed and Red Ruffed Lemurs, a Fossa, Sumatran Tigers, Maned Wolves, a Giant Anteater, a Kookaburra, Black Howler Monkeys, Burmese Star Tortoises, and a little farm area. There are Chickens and Peacocks (Yes they are all male. And one of them is pure white!!) that are free roaming about the zoo. The expansion to the zoo will open June 4th. This will contain Cassowaries, Pygmy Hippos (Their exhibit being one of the largest of it's kind), an Okapi, Southern Ground Hornbills (Who will go on exhibit with the Okapi, Caribbean Flamingos, a Serval, a Sand Cat, and a Black-footed Cat that was just born at a zoo in Texas will be added when he is old enough to be separated from his mom. This expansion will also give new homes for the Fishing Cats (Doubling their space) and the Red Pandas (Tripling their space). The center is also planning on expanding the Meerkat, Javan Gibbon, and Sumatran Tiger habitats. They also participate in breeding programs for these species. Currently the center has had 21 African Penguin chicks, 3 Fishing kittens, a bunch of Maned Wolf and Asian Small-clawed Otter pups, 2 Javen Gibbon babies, 2 Screaming Hairy Armadillo pups, and in the future hopes to add baby Pygmy Hippos, Red Pandas, Kookaburras, Sumatran Tigers, Caribbean Flamingos, and Okapis to that list!
