The marquee attraction here is the whizbang Ocean Wonders center. Dedicated to sharks, and the Grand Canyon-deep underwater "Hudson Canyon" that’s just 40 miles off the coast of the city, this center showcases great whites, leopard sharks, giant rays and other sealife in massive, walk-throughable tanks. It also holds dozens of educational-but-not-preachy interactive exhibits on sustainable seafood, ocean trash, and the importance of sharks to the eco-system. On its roof is an open-air café where adults can relax while their kids play with the "touch tanks" just steps from the tables. In addition to Ocean Wonders (truly a wonder), there’s a show where you’ll see sea lions perform; outdoor pools where black-footed penguins, seals, and sea otters cavort; and Conservation Hall which has massive Amazonian river fish on display, among other sealife.
