This is the theme of the "Jellies Invasion" exhibit at Baltimore's National Aquarium.Jellyfish expert Jennie Janssen, the aquarium's Manager of Changing Exhibits, took me behind the scenes recently. These drifters graze on zooplankton, keeping populations of some smaller animals from growing out of control.In the near future, jellyfish worldwide may be heading for a population explosion. Chillin' Out.Sea nettles, also called jellyfish, normally would have trooped into the Chesapeake Bay by now, sending swimmers farther up rivers and streams toward fresher water.
The Inside Scoop on the Chesapeake Bay — Adventure. In this setting, over a backlit field of blue, the jellies were stunning.The tanks are set up to take advantage of the jellyfishes' need to swim against the current. And, sea nettles help protect baby oysters by eating comb jellies during the summer months when oyster larvae are most abundant.I saw it just a second too late. Sorry, your blog cannot share posts by email. It is mainly found in the Chesapeake Bay and along the East Coast of the United States I remember as a teen squeezing my eyes shut as I dove off the side of our boat into the Severn River. Fun. Chrysaora chesapeakei is a sea nettle from the family Pelagiidae. Raleigh Hood with the University of Maryland’s Center for Environmental Science believes it could be just a normal sea nettle cycle.Either way, water-lovers are enjoying what has been provided this season — few sea nettles.Copyright © 2019-2020 www.chesapeakeliving.com. We share the downlow on where they are and how to avoid them.
Jellies, it turns out, have been around for some 600 million years, and they are very good at adapting. Severe allergic reactions (anaphylaxis) are uncommon to jellyfish in U.S. waters, but emergency treatment is essential in such cases. The tentacles wrapped around my head and shoulders as I pierced the surface of the warm water. The lion's mane jellyfish, the world's largest jelly, can grow up to eight feet across in far northern waters. These maps are experimental and depict the probability of encountering sea nettles (not their abundance or density) in the Chesapeake Bay area. The nettle uses its oral arms, which hang from the center of the bell, to move food to its mouth.When oysters are in their floating larval stage they are prone to predation by nettles and comb jellies. The sea nettle can cause a painful sting when encountered. Knowing where and when to expect this biotic nuisance may help to alleviate an unpleasant encounter.
Males release sperm into the water.
Water flow inside the tanks is adjusted based on the size of the animals and with the aim of keeping the jellies in good viewing positions for visitors.Although mature nettles can achieve a weak swimming motion by contracting and relaxing their bell, their location is mostly controlled by winds and currents.

Since then, it is also commonly known as the bay nettle. Sea nettles (also called jellyfish) start swarming the Chesapeake Bay in mid-summer. All rights reserved.
Scientists point to the out-of-balance state of our planet's oceans. Females pump the sperm through their bodies and release tiny larvae, called planulae. Their walnutshaped forms reach a maximum size of about five inches and can glow (through bioluminescence) at night if disturbed.Appearing mostly in the southern Bay, the moon jelly's clear, disk-shaped bell is fringed with hundreds of short tentacles. In the tributaries, however, Sea Nettles can consume 50 – 90% of the copepods daily, and copepod abundances seem to decline over the summer, possibly due to this predation. Lightweight protective clothing, like a lycra “swim skin” or panty hose, or a layer of petroleum jelly spread on unprotected skin, will protect a swimmers against stings. – Dr. Jennifer Purcess, resident scientist at Shannon Point Marine Center, Western Washington University. Sea Nettles consume up to 50% daily of the bay … I highly recommend visiting this popular exhibit in person, but don't wait too long.
Wally Gobetz/Flickr. More than 18 million people live in the Chesapeake Bay watershed. Although both Atlantic sea nettles and comb jellies eat larval oysters, the sea nettle spits them out unharmed. Better than most fish.While, jellyfish tolerate the effects of the pollution we dump into our water, fish populations decline.
Since they like warmer saltier water, more nettles are likely during dry, hot summers.In case you needed another reason to fight for clean water, getting our Bay back in balance with healthy fish and turtle populations may help control the nettle.
If you are stung by a jellyfish, liberally sprinkling a meat tenderizer or baking soda (or vinegar for Physalia) on the sting may reduce the irritation. As the weather heats up, many Bay residents and visitors consider taking a swim in the Chesapeake. These true jellies can grow up to about 12 inches in diameter and temporarily shrink to one-tenth their size to conserve energy when no food is available.Sea nettles eat zooplankton and small fish, worms, and crustaceans. With fewer of the jellyfish's natural predators and jellies snapping up more food, a vicious cycle begins.
