![]() ![]() Moon jellyfish are usually transparent or milky white, although they can be blue, red or orange. They are quite large and colorful jellyfish. They are translucent animals that can grow to be 16 inches in diameter. Pretty badass names for some crazy creatures. Among them are the polyunsaturated fatty acids arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid. Moon Jellyfish are wonderful sea creatures. Well, according to Maine Lobstermen’s Community Alliance, Maine has a few different species of jellies in its waters: comb, moon, and lion’s mane. Several essential fatty acids were found in the German moon jellies. "As we see an increase in jellyfish, I suspect that we will also come to see a change in predator populations-especially in areas where the abundances of usual prey items might be endangered by a changing environment," says Javidpour. On a global scale, marine environments are changing, and an increasing abundance of jellyfish is thought to replace other prey items in the oceans. They can't really swim away when predators start eating them." "Jellyfish often come in shoals and they move slowly through the water. So, if the predator doesn't have to spend much energy on eating loads of jellyfish, this preying strategy begins to make sense, she explains: As an example, researchers have observed a salmon eat a jellyfish 20 times faster than it took for it to eat a shrimp. In other words: Low food quality can be weighed up by high food quantity. ![]() It is true that a predator does not get much from eating a single jellyfish, but if it eats many, it will make a difference and provide the predator with valuable fatty acids," she says. "Jellyfish are likely to be more than just an opportunistic prey to many organisms. Their content of fatty acids varied with seasons, and variations linked to developmental stages were also found: mature individuals with reproductive tissues had the highest content. The researchers collected moon jellies from North German Kiel Fjord every two weeks for two years. Co-authors are Vanessa Stenvers from University of Groningen and Chi Xupeng from Chinese Academy of Sciences. Javidpour is Principle Investigator and co-author of the study, published in Journal of Plankton Research. Fatty acids are vital components of cell membranes and play a crucial role in processes like growth and reproduction," says marine biologist and jellyfish expert, Jamileh Javidpour from University of Southern Denmark. The adult may grow as large as 40 cm (16 inches) in diameter. "The jellyfish in our study showed to contain some fatty acids that are very valuable for their predators. moon jelly, (genus Aurelia ), genus of marine jellyfish of the order Semaeostomeae (class Scyphozoa, phylum Cnidaria) characterized by their pale translucent bodies and commonly found in coastal waters, particularly those of North America and Europe. The study is based on moon jelly samples from a German Fjord. The local shared that she has seen a lot of these jellies washing up on shore recently, so I guess I won't be swimming in the ocean this summer.Now a new study may explain why these predators bother to eat the gelatinous creatures. These bad boys are the largest jellyfish in the world and their 1,200 stinging tentacles can grow more than 100 feet, longer than a blue whale. Trust me, you're going to want to click that link. I can't embed her post into this article but you can check it out on the Maine Wildlife Facebook page right here. Just to make my fear even worse, a Mainer posted on Facebook recently showing a huge lion's mane jelly that washed up on shore in Blue Hill, Maine, on March 25, 2023. Turns out, lion's mane jellyfish are freaking MASSIVE! They are also referred to by names such as moon jelly, saucer jelly, common sea jelly and even violet moon jellyfish. Massive Lion's Mane Jellyfish Washes on Shore in Maine Moon jellyfish are a species of jellyfish, known by the scientific name Aurelia aurita, and are found mostly in warm and tropical waters, near sea-coasts. I am talking about jellyfish that are so insane looking, I thought they were fake. I've seen posts since that day showing incredible jellyfish that have been spotted in Maine. But it was a small little thing and looked harmless, so although I was stunned, I didn’t let it ruin my day. When I first became aware that Maine even had any jellyfish at all, I was walking on the beach and saw a blob in the sand and that was my great awakening. Well, according to Maine Lobstermen’s Community Alliance, Maine has a few different species of jellies in its waters: comb, moon, and lion’s mane. Now, I’m shaking every time I step into the ocean and it’s not just from the freezing temps. ![]() I used to jump off ferry docks and not think about getting stung by a jellyfish or dive off an anchored boat and not have one thought about a shark. Moon jellyfish are definitely creatures of the water, but the truth is: they can barely swim. ![]()
