More than 10,000 creatures of the sea make New York City's only aquarium their home. It's an attractive layout in which tropical fish, sea horses, and jellyfish luxuriate in large tanks. Otters, walruses, penguins, and seals lounge on a replicated Pacific coast, and a 90,000-gallon tank is home to several different types of sharks. The New York Aquarium is America's best aquarium and it is located in Coney Island, Brooklyn.
