The city’s aquarium broke ground in 1978, and Congress granted it national status a year later. The sprawling complex is now the crown jewel of the Inner Harbor and home to nearly 20,000 species. For a quick visit, stick to the Peter Chermayeffdesigned Glass Pavilion
and adjacent Pier 3. Start at Animal Planet Australia: Wild Extremes (above), and seek out the Archerfish, an unassuming swimmer that captures bugs by spitting a jet of water at them, knocking them off their perch. After, cross over to Pier 3. On the first floor, find Blacktip Reef, where
500-pound green sea turtle Calypso (above) cruises with the display’s namesake sharks among 3,000 pieces of handcrafted coral. At Living Seashore (above, left) on the third floor, visitors touch Atlantic stingrays and even luminous moon jellies. If time allows, ascend to the Rain Forest for a glimpse of Golden Lion Tamarin monkeys scampering through the treetops.
