New York Aquarium | Brooklyn, NY

See a living re-creation of the Pacific coastline, and catch sight of various East River species. There's also a lively sea lion show, plus some truly awesome sharks and sea jellies. Fantasize about upcoming summer months as you visit Glover's Reef, a 150,000-gallon tank stocked with 35 species—give or take—of marine life from the coast of Belize, including jawfish and moray eels. At the Explore the Shore exhibit, kids can learn facts about the ocean and the animals that in and on it; the salt-marsh area mirrors the Jamaica Bay wetlands, allowing an underwater view of sheepshead minnows and hermit crabs.
