Lion’s Mane Jellyfish, also known as Winter Jellyfish, are one of the most well-known species of jellyfish due to its size, distribution, and some shockingly poor photographs that have been Photoshopped and have circulated on the internet. To begin, they are the largest species of jellyfish that are currently known to exist.
- Their tentacles can grow to a length of about 120 feet, and their bells can have a diameter of more than 6 feet (most of the time, you’ll find large specimens of this species in the icy waters of the Arctic; you’ll find smaller specimens the closer you get to the equator).
- Their bell is divided into segments (eight in all), however it might be difficult to perceive these segments since they are typically filled with multicolored gelatinous goo inside the bell.
Nevertheless, their bell is divided into segments. This gel can appear in a variety of colors, ranging from pink to yellow to even reddish purple. They got their name from the bushy array of tentacles that dangle from its bell. These tentacles tend to be thick and rich, much like a lion’s mane, which inspired the name.

Winter jellies spend their entire lives in the icy waters of the Arctic, Northern Atlantic, northern Pacific, Baltic Sea, North Sea, English Channel, Irish Sea, North Sea, etc. Their home range is always in the frigid waters of these regions.
Do you see a pattern developing here? Because all of these waters are frigid (typically about 50 degrees Fahrenheit or lower), you won’t find them in the Chesapeake Bay during the summertime. As the water temperature decreases over the winter, these jellies make their way into the area since they are unable to survive in warm water.
- They are plankton that live in shallow water and drift, although their lifespan as adults in the wild is just about a year or two (medusa).
- In the seas and bays where they reside, lion’s mane jellyfish are the top level predators.
- They prey on other types of jellyfish, plankton, tiny fish, and invertebrates.
Because they need to eat, they prefer to stay towards the top of the water column. They won’t travel much deeper than 10 meters, and they are almost never seen deeper than 20 meters. This implies that they are rather simple to identify in water that is both cold and transparent.
- I thought it would be helpful to show you some photographs to assist you in seeing and identifying them because there is such a wide range of variation in the color and shape of each one.

Because of some poor Photoshop work, many people have the mistaken impression that lion’s manes are composed entirely of enormous, ginormous jelly. In most cases, you won’t find one that is any larger than a hubcap. What is said to be a gigantic lion’s mane jellyfish is seen here in a photo that has been poorly edited with Photoshop (Photo: Mental Floss).
- It is important to use extreme caution while approaching lion’s mane jellyfish since they contain tentacles and can sting.
- It would be wise to keep a safe distance and observe them from afar.
- Even when detached from the rest of the animal or lying on a beach, its tentacles are still dangerous.
- If you are stung, you can relieve the pain using meat tenderizer (peeing on a person is an old wives tale and will just make a mess).
Remember that despite the fact that they may sting, they play a crucial role in the ecosystems of the oceans. They are apex predators, which means that they take care of other jellyfish, fish, and invertebrates, maintaining the ecosystem’s equilibrium.
- In addition, sea turtles, particularly the critically endangered leatherback sea turtle, use lion’s mane as a substantial component of their diet.
- They are also a source of food for turtles that live in watery environments.
- Plastic bags used for shopping should always be recycled, and they should not be allowed to enter rivers.
This is because turtles with poor vision sometimes confuse floating plastic bags for jellyfish, and when they do, they consume the bags—which can be fatal. Turtles who have poor vision may be fooled into thinking that a floating plastic bag is a jellyfish (Photo: DW.
Where are jellyfish in the winter?
By Stephanie Smith (Photo by Will Parson) (Image by: The 20th of January, 2017 On January 18, 2017, a visitor with a lion’s mane jellyfish was spotted in Spa Creek in Annapolis, Maryland. The lion’s mane jellyfish, also known as Cyanea capillata, may be seen in the Chesapeake Bay region between the months of late November and March.
This species is also known as the “winter jellyfish.” Because of their propensity for the extremely low temperatures of the Arctic, they will only go south from more northern latitudes when the water is sufficiently chilly. Because the kind of lion’s mane jellyfish that frequents the Bay is planktonic, which means it floats wherever the currents carry it, the presence of lion’s mane jellyfish in the Chesapeake Bay can be unpredictable despite the fact that it is not an unusual sighting there.
Because they prefer to float near the water’s surface, they are easy to notice when they are brought to the region by water currents and cold temperatures. This makes it possible for them to migrate to new locations. Tentacles of lion’s mane jellyfish are poisonous, much like those of the sea nettles that are common during the warm summer months.
- However, because there are fewer people swimming in the cold waters of January (with the possible exception of those taking part in a Polar Bear Plunge), it is less probable that swimmers may be stung by a lion’s mane jellyfish.
- Lion’s mane jellyfish that visit the Bay often have a diameter of between four and six inches, making them approximately the same size as sea nettles.
However, if you continue your journey to the north, you could come upon a considerably larger species. A lion’s mane jellyfish with a body measuring more than seven feet in diameter and tentacles measuring more than one hundred twenty feet in length washed ashore on a beach in Massachusetts in the year 1870.
It is the biggest specimen of its kind ever reported. Find out more about the several kinds of jellyfish that inhabit the Chesapeake Bay.

Can jellyfish live in the cold?
A group of scientists from the United States and Poland have made it a practice to see behind the thick ice that covers the waters of the Chukchi Sea, which is located between Alaska and Siberia. This practice has been going on for a number of years. The following is a description of one of the animals that caught their attention: Jellyfish of the species Chrysaora melanaster, also known as the northern sea nettle, can be seen moving slowly on the ocean floor while dragging their tentacles behind them.
This type of jellyfish is also known as the northern sea nettle. At first glance, it appears to be nothing more than a jelly, but the discovery of it came as a shock to the experts. In point of fact, Andy Juhl, who works at the Lamont-Doherty Earth Observatory at Columbia University, gave a pretty brief description of the event, saying, “e saw them, and it was sort of bizarre.” Adult jellyfish have the tendency of floating around in the water column, for one thing, which is one of their defining characteristics.
The researchers who investigated these floor-crawling jellyfish assume the creatures may have been picking food off the sand with their long tentacles. This is a somewhat uncommon behavior for these jellies, so the researchers were intrigued by the possibility.
- What’s even more unbelievable? The collection of footage that the scientists have compiled shows that the jellyfish are able to live under the ice for a far longer period of time than anyone had anticipated.
- Jellyfish begin their lives as larvae that swim around and eventually find a location to settle on the ocean floor.
There, they continue to develop into a polyp that protrudes from the ground. When the polyp is mature enough, it will begin to produce additional larvae that swim and will eventually develop into the typical adult jellyfish that floats, known as a medusa.
Traditionally, it is believed that the adults would emerge in the spring and continue to live into the fall. After that, they will give birth to new larvae and then pass away. The jellyfish that live beneath the ice in the Chukchi Sea, on the other hand, appear to be able to live for more than a few months: they spend the whole winter hunkered down beneath the ice.
This is not only a fascinating finding on the lifetime of jellyfish, but it may also be an essential piece of knowledge regarding the mystery swarms of jellyfish. According to the findings of the researchers’ study, “Jellyfish and ctenophore blooms are of increasing concern for human industry in marine environments,” yet the report also notes that “bloom formation remains little understood.” These jelly swarms have the potential to create a bit of a problem for the fisheries in the nearby Bering Sea.
There are years when the local jellyfish population grows to such an extent that it causes fishing nets to become clogged with jellyfish. Marine researchers have been attempting to discover both the reason why this occurs as well as a method for accurately predicting future blooms. According to the Chukchi Sea experts, the jellyfish may be able to make it through the winter provided there is an abundance of food, the sea ice is thick enough to shield them from the harsh winds of storms, and the water is kept at a temperature that is sufficiently cool.
Jellyfish are able to survive on less food because their metabolisms slow down when they are exposed to cold temperatures. After a few of these ice-heavy winters in a row, there is a possibility that there will be an excessive amount of adult jellyfish, both new and old.
- And it’s possible that this occurrence isn’t limited to just this one species; it might be more prevalent than that.
- In a world where temperatures are always fluctuating, it will be crucial for preserving fisheries to have a solid grasp of the link between winter weather and jellyfish jamborees.
- And if that means there is a need to capture more videos of jellyfish bobbing gracefully down the ocean floor, then it’s a win-win situation all the way around.

- When lactose, also known as milk sugar, is exposed to a culture of the bacterium Lactobacillus bulgaricus, it undergoes a transformation that results in the production of lactic acid.
- People who have trouble digesting the sugar in milk might benefit greatly from the use of yogurt as a dairy product.
- Because preserves and various other sweets are occasionally added, the calorie content of the reconstituted milk can sometimes be higher than that of the original milk.
However, this is not always the case. Some yogurts have milk solids added to them, which causes them to have increased amounts of protein and calcium. Yogurt has a longer shelf life than regular milk because, being a fermented product, it is too acidic to permit the growth of most microbes that cause food to decay.
This results in yogurt having a longer life. The question is: “Is it possible to find an albino roach?” A. Albino insects do not appear frequently. A genuine albino roach would have a pinkish hue rather than a white one. Immediately after their molt, roaches have a snow-white appearance, but after a few hours, they have returned to their normal color.
In order to make room for their expanding bodies, roaches and many other kinds of insects and crustaceans must periodically shed and replace the stiff, exterior skeletons that they are born with. This process continues until they reach adulthood. Do jellyfish go into a dormant state during the winter? A.
Jellyfish do not hibernate in the traditional sense; rather, they enter a dormant state during the winter months. Jellyfish that are able to swim freely and are in the medusa stage of their reproductive cycle pass away after they have released their eggs during the warmer months. The eggs develop into the budding stage, at which point they produce polyps, which then sink to the substrate and spend the winter there.
Following the end of winter, the polyps continue their life cycle by transitioning into the medusa stage. To what do you attribute the fact that trailer parks are so frequently hit by tornadoes? A. There is nothing about trailer parks that makes them more likely to be struck by tornadoes; they are just in the path.
Are there jellyfish seasons?
Jellyfish have recently made their way into the waters along the coasts of Delaware, Maryland, and Virginia, where they have become an unwelcome guest. Because of the rising temperatures of the Atlantic Ocean, experts believe that jellyfish season is beginning earlier in the year and continuing for a longer period of time.
- Because there are now more jellyfish in the water, there is a greater risk that swimmers will get stings.
- According to Ann Barse, a professor of biology at Salisbury University, jellyfish may begin to arrive as early as May and may remain in the area until September.
- The gelatinous, bell-shaped organisms are drawn to warmer waters, and here is where they concentrate, both off the coast and in the bays that are located inland.
Warmer water caused by climate change does not result in an increase in the total quantity of jellyfish in this region on an annual basis; nevertheless, it does lengthen the amount of time that organisms that are capable of stinging humans remain in seas where people swim and fish.
- According to Barse, the population of jellyfish may be traced back to two different factors: pollution in the water and a decline in the number of oysters in the bays.
- She explained that “so in the past in the bay, the principal filter feeder is the eastern oyster,” whose population has been reduced to a fraction of one percent of what it used to be.
“So in the past in the bay, the primary filter feeder is the eastern oyster,” The phytoplankton and zooplankton in the water would be removed by the filter feeders, which would lead to a reduction in the number of jellyfish in the ecosystem. According to Barse, their diet consists of plankton, tiny fish, and various types of jellyfish.
They are carried along by the natural currents of the ocean, and it is often at this time of year that the “jelly,” as some scientists refer to it, makes its way into the rivers, bays, and ocean on the Delmarva Peninsula. According to Captain Kent Buckson of the Rehoboth Beach Patrol, the middle of August and the month of September are the traditional months in which jellyfish congregate in the seas off of Rehoboth Beach.

However, he stated that the beach patrol has already received several complaints of jellyfish sightings thus early in the season. “Over the past week, we’ve been hit with a couple stings,” he remarked. “In the last week, there have been an abundance of jellyfish that do not sting (moon jellyfish), and the water has become rather cloudy as a result of their presence.
Is it jellyfish season in NJ?
WHEN DO THEY APPEAR IN NEW JERSEY WATERS? Clinging jellyfish, like other types of jellyfish, begin to proliferate when the water temperature and the availability of food are both suitable. Blooming season in New Jersey begins around the middle of May and continues until the beginning of August for adults (or until bay water temperatures reach or exceed 82oF).
