What Do Jellyfish Eat? Jelly fish are beautiful creatures. There is 90% of water in their bodies but still they flow along with the flow of water. These creatures eat meat and mate constantly. Jelly fish have certain things which they have in common with other animals.
These are the only similarities they have but that should not refrain us from studying jelly fish. What are the eating habits of jelly fish and what is the food given to jellyfish you kept as pet? Let s try to figure out.
What Do Jellyfish Eat in the Wild
Jellyfish have been living in the ocean from a very long time. The best thing is that they can adapt themselves in every type of water. The can also live in coastal waters that are shallow.
Jellyfish are known to depend on other animals for their food. They are very good predators. It is very surprising that how can a round thing that is mostly made of water containing 7-8 tentacles eat other animal?
Jellyfish are able to paralyse their prey by stinging it. There are cells present in the tentacles of jellyfish that attacks their food and the creature is shocked as they eat them. The top portion of the body of jellyfish is like a bell where is mouth is located.
The mouth of jellyfish is like an opening found in mammals. After stinging its prey the jellyfish swallows the food in the opening and eats it within no time. The process of digestion has to be quick as it is not easy for the jellyfish to move around in the water with heavy food inside its body.
The waste is also taken out from this opening. Although this may sound weird to humans but the physical mechanism of jellyfish is very different from mammals which makes this process interesting.
Favourite Food of Jellyfish
But what is that which jellyfish hunt with their deadly tentacles? The answer is living creatures that is quite small which they can catch with their tentacles.
For instance creatures like plankton, crustaceans, and eggs of fish, fish, and other jelly fish are the favourite foods of jelly fish. They even eat plants which they come across.
You should know that jellyfish are not avid hunters and will only eat what they may get. Their tentacles work just like the net of fisherman for them.
The process of swimming of jellyfish involves contraction and expansion of their bodies. When the bells of these creatures expand they get more area to track their prey.
When jellyfish are found in big groups it is called bloom. The blooms of jellyfish can be a big problem for fisherman and other creatures who frequently visit the area of bloom.
This is because the tentacles of jellyfish cover a lot of area and so they can eat everything which comes under that area. It implies that jellyfish eat the food of bigger sea creatures which limits the survival of other creatures as the bloom moves on.
The diet of jellyfish is full of variety. They are able to eat anything that is trapped in their tentacles if it is a living creature. Jelly fish are also known to eat small creatures of the sea.
Although jellyfish do not eat everything in the ocean but they can be a big problem if they form a bloom as they can finish the food of other sea animals. Jellyfish can reduce the population of habitats of ocean in spite of the fact that they do not eat big creatures.

Best Food for Jellyfish Which is Kept in an Aquarium
The jellyfish which is kept in an aquarium leads a much different life than the jellyfish in the wild. In addition when they live in an aquarium they eat very less than a bloom can. If you have kept a jellyfish or planning to get one then you should know about the foods that can be added to your tank.
The Aquarium Food for Jelly Fish
It is not very commonly seen that people own a jelly fish aquarium but this trend is becoming popular. The most common jellyfish which is kept by people in the aquarium is known as “moon jellyfish”. There are only two types of moon jelly fish that is found and it is not easy to get them. But if you want to keep a jellyfish you should know about its eating habits.
Feeding Your Jellies
It is important to keep your jelly fish full otherwise they will get weak and lazy. Jellyfish are transparent and you are able to see through them. For example if your jellyfish has not consumed any food you can see the bluish colour in their bellies. After about an hour of eating food you can see the red colour of the food being digested in front of your eyes. If you are able to see the reddish colour of the food inside the jellyfish it means your jellyfish is getting the right amount of food to eat.
Do You Know The Right Food for Your Jellyfish?
Jelly fish looks great whether they are living in an ocean or an aquarium. You may not have kept a jellyfish in an aquarium but you would certainly want to see them in an aquarium. You may not know that they even like to eat eggs of fish and small shrimp.
If in case you want to keep a jelly fish tank at home you should do a proper research in order to find a good source to get food. Jelly fish do not eat much as they are known to eat what they get.

TYPE OF JELLYFISH
The NOAA Okeanos Explorer recently discovered a new type of Jellyfish that pertains to the Crossota gender which is pushing through the ocean. This is a very impressive, beautiful specimen, but many others will impress you with their unique appeal and distinct set of visuals, to begin with.
A thing to note here is that this particular type of jellyfish is named based on the bell projections that will remind you of the cauliflower plant. You can find it in the West Africa region, as well as the Atlantic Ocean, Indo and Mid-Pacific.
This is a rather large jellyfish species, as it can reach diameters of around 1.5-1.9 feet. They are known as a delicacy in some regions like Japan and China. However some people do use them for medical purposes.
A thing to note about this species is the fact that it’s colorless. Aside from that, it has no less than 50 different tentacles, and these tend to line near the bell which is similar to glass. It’s one of the few jellyfish species that seems clear in daylight.
Based on data from the Monterey Bay Aquarium, these are bright, and they do have some glowing points right near the globe. What leads to the bioluminescence includes things like aequorin which is a protein activated by calcium, and you will also find GFP that gets the aequorin energy and delivers a green light based on that.
The protein is helpful for scientists as it allows them to improve their research and find better results in a very simple and efficient manner.
Although many species are rather fearful, the white spotted jellyfish isn’t one you should be afraid of. The venom isn’t bad for humans, since this species is only killing zooplankton for its survival. It can filter up to 13k gallons of water as it tries to find the zooplankton.
The issue here is that they tend to eat a lot of zooplankton to the point where crustaceans and fish will find it had to stay alive. You can find them in regions like the Caribbean sea, as well as the Gulf of Mexico as well as the Gulf of California.
Bloodybelly comb jellyfish
This is a rather common name, but a distinct one at that. They do offer a very impressive light show, and they can be rather impressive when they come out of the abyss. The thing to keep in mind here is that they aren’t related to jellyfish from a technical perspective.
While they lack tentacles, they do have cilia, which are projections similar to hair, used for swimming inside the water. This species is known for its red look, however, at massive depths, this still seems like black. However, they do get added protection when they come in lighted areas due to their impressive design.
Black sea nettle
The black sea nettle is another red jellyfish. This one is known to appear in Baja California, Southern California, and the Pacific as a whole. It’s a very large species, and it can have a bell that’s up to 3 feet, and the arms can have up to 25 feet in total. Yes, this is a very scary sight and one that will impress you quite a lot for the longer term.
Despite the fact that it’s a very large species, the black sea nettle is known for offering a multitude of interesting features and ideas. They aren’t exactly old. Instead, they were just uncovered a few decades ago. Scientists don’t know where the creatures stay and what they want when they appear in groups.
Flower hat jellyfish
This particular species is rather odd, and you can find it in regions like the Southern Japan coast and the Western Pacific as a whole. You can also find it in Argentina and Brazil. This is not a species that pulses, instead you can mostly find it near the ocean floor. The reason is simple; its diet consists out of smaller fish!
Despite the fact that they look great, these creatures are very challenging to deal with, and they do sting a lot. The MBA mentioned above stated that their sting is very painful. It can bring a bright rash, and in the end, it can easily interfere with shrimp fishing!
Mediterranean or fried egg jellyfish
Are you interested to see how this species got its name? Simply put, this is known as the Mediterranean jellyfish because it can be found mostly in the regions near the Mediterranean Sea. The thing to note here is that their bell is surrounded by a lighter ring.
Another thing you have to note here is that they have a truncated mouth and the projections are long, sometimes even disk-like. They can survive for multiple months, and they will die right when the water will end up cooling down.
Like other jellyfish species, they also feed on zooplankton, and they do tend to eat some smaller fish too. They do hide inside the tentacles to receive the right amount of protection, a rather interesting thing to say the least.
Known as the Coronate Medusa, the Atolla jellyfish is living in the deep sea regions. Because of that, it does have some interesting bioluminescent capabilities. They tend to attack their prey and stay away from enemies, which is rather nice, to begin with.
When this type of jellyfish is attacked, it will usually generate flashes similar to a police siren. This will end up attracting more predators that will most likely find the initial attacker a much better meal. This allows the jellyfish to escape, which is a rather distinct and elaborate plan.
That’s why some people call this species the alarm jellyfish because the way it works makes it feel like a real alarm.
This particular species has two stomach pouches, and it keeps the tentacles in front of it while swimming. This makes it very efficient as a predator, and it can provide you with some great results in the end.
Some species can grow within their mother which will allow them to receive better care and protection. At some point, they will leave their mother, and they will find another jellyfish, attack the flesh and stay in their body.
All these jellyfish species are rather distinct, and they do show the uniqueness offered by these amazing creatures. With this information, you should be able to know all you want about jellyfish and the way they live, where you can find them and all the other pieces of relevant info that you always wanted!
