Nestled inside a massive refurbished warehouse in Dallas' Historic West End District, this privately-owned aquatic wonderland is home to countless varieties of marine life (many of which are endangered) from all over the world. In addition to stingrays, piranhas, electric eels, poison dart frogs and Orinoco crocodiles, the aquarium boasts a 20,000-gallon walk-through exhibit brimming with hundreds of Indo-Pacific fish-- as well as a forty-foot long glassed-in tunnel filled with sharks circling overhead. But there's more than fish that meets the eye, visitors can commune with everything from three-toed sloths, manatees and giant river otters to penguins, snakes, tree kangaroos and even a few jaguars. There's also a lush three-level (seven stories in height) recreated South American rain-forest-- complete with free-flying birds, pink flamingos, monkeys and a 40-foot waterfall. Not-to-be-missed are the talks and feeding sessions held throughout the day. Be sure to check the website schedule before you go.
