If you have been to the beach or out on a boat recently you have probably encountered a jelly or two, perhaps even more. This is the time of year that jellies are most prevalent in the mid-atlantic region. So why do we see so many of them during the summer??
Jellies are found in most bodies of water, including the Atlantic Ocean, the Chesapeake Bay, and even in Baltimore’s Inner Harbor. In fact, some Aquarium employees saw a bunch of comb jellies in the harbor earlier this morning. In this region, most jellies are seasonal. The greatest variety of jellies are found in the lower bay, in the coastal bays and, offshore in the Atlantic Ocean were salinities are higher. Some of the more common species include:
- Moon Jellies, (pictured to the right) found in the Lower Bay and Atlantic Ocean. In the summer months the remains of moon jellies can often be found washed up on the beaches, but they rarely sting people.
- Atlantic Sea Nettles, found in the middle and lower bay and seen in late spring, summer and early fall and the most likely to sting you. They sting thousands of beach-goers each season!
- Comb Jellies, found throughout the bay and ocean year-round but most commonly seen in the warmer months. Comb jellies do not have the ability to sting.
- Lion’s Mane Jellies, found in the bay from late November through May, also known as the winter jelly and also deliver a powerful sting.

Jack Cover, the Aquarium’s general curator of fishes and rainforest exhibits, refers to jellies as living lava lamps. Many exhibits around the country show jellies as living art. Visitors see them as majestic and mesmerizing. When visiting our new Jellies Invasion exhibit, one local reporter referred to them as being “other-wordly.”
There seems be a new form of jellies artwork…a 600 ft crop circle in a jelly pattern that recently appeared in a barley field in UK! It’s gaining a lot of media and tourist attention as one of the most intriguing crop circles ever seen in Britain. Click here to read more about this amazing form of art.

Jellies and Dinosaurs are invading Baltimore’s Inner Harbor in a Waterfront Invasion. Are you prepared? This summer the National Aquarium and Maryland Science Center will have wonderful displays of two very popular prehistoric creatures, each with their own story of invasion…
Though prehistoric, Jellies are still thriving and invading oceans across the world. In fact, in 1990, eight years after the comb jellies first invaded the Black Sea, their biomases totaled about 900 million tons in the sea – that’s more than 10 times the weight of the total annual fish catch from all the world’s oceans.

Jellies Invasion: Oceans Out of Balance opens in less than a month! As you read last week, our aquarists begin collecting, maintaining and breeding animals months before an exhibit opens. The jellies are being collected from natural habitats and from other institutions around the world. In fact, we just received a shipment of blue blubbers and lagoon jellies last week from Japan. Take a look at some of the blue blubbers:
The blue blubbers are one of nine species that will be featured in the exhibit. Even after Jellies Invasion opens to the public, the aquarists will continue to grow our collection of jellies. Aquarists are constantly replicating natural habitats, feeding, caring for and breeding the animals so they acclimate and flourish. The ultimate goal of our “jellies lab” is to establish and maintain breeding cultures of jellies so we can provide a variety of specimans for our visitors to see in the exhibit.

Ever wonder what it takes to create an exhibit at an Aquarium? It’s a huge team effort with two goals: to offer a healthy habitat for the animals and a great visitor experience. We have been working dilligently for the last year to create Jellies Invasion: Oceans Out of Balance, opening Memorial Day weekend. With less than a month go, let’s take a look back at the process.
It’s not as easy as it sounds to bring a new animal collection into the fold. First, there is the issue of space―there is only so much of it. Jellies require much more water than the frogs that previously occupied the same area of the Aquarium. So the first order of business was to provide for sufficient water flow and drainage to the area. Workers distributed water from the main building, poured a new concrete floor and created a trench drain system. Most of this work had to be done off-hours to minimize visitor inconvenience.
