If you have not visited the National Aquarium this summer, there is still plenty of time to see their mesmerizing $2.2 million exhibit, “Jellies Invasion: Oceans Out of Balance” at the Marine Mammal Pavilion.

The exhibit displays nine different species of jellyfish and explores their 650 million-year-old history on earth. Underlying this fascinating presentation of these mysterious and gelatinous invertebrates – some of which can be found in the Chesapeake Bay and Inner Harbor – is a slightly portentous message about their unwavering ability to survive even the most intolerable conditions and what that means for aquatic ecosystems on the whole.

Tickets range from $15-$25 and can be purchased online or by calling 410-576-3800.
