Established in 1873, the country's oldest aquarium has an incongruous location inside the lower level of the Commerce Department Building, near the massive Ronald Reagan Building. More than 1,200 fish and other creatures—such as eels, sharks, and amphibians—represent 250 species of fresh- and saltwater life. Special exhibits highlight the animals and habitats of the National Marine Sanctuaries Program and freshwater ecosystems of the United States and its territories. Affiliated with Baltimore's National Aquarium, the aquarium is operated by a nonprofit organization. The exhibits appear somewhat dated, but the easy-to-view tanks, low admission fee, and absence of crowds make this a good outing with small children. The cafeteria is a great place to stop for a snack.
