The jelly fish is one such organism that does not have a specific organ that can be said to be its digestive system as most living organisms have. The gastro vascular cavity consists of a lining called the gastro dermal lining and which is responsible for absorbing all the nutrients that the jelly fish consumes. In most cases blooms or swarms, which is the name given to a group of jelly fish, survive on planktons and small organisms found under water. There hasn’t been a specific item to answer the question what does jellyfish eat, but they usually survive on smaller fish and minute organisms found underwater.
The diet of the jelly fish is mainly made up of smaller fish as it is carnivorous organism, but this is not the only food that it eats. For knowing more about what does jellyfish eat, you should also know that it also takes in many dead as well as living organisms in a huge number. The jellyfish can eat eggs of fishes, smaller fishes and crustaceans as well as invertebrates and zoo planktons. It catches its prey in its tentacles and these are very poisonous in many varieties of jelly fish.
The answer to what does jelly fish eat in aquariums and tanks is quite different to what does jelly fish eat in its normal habitat. The jellyfish in tanks and aquariums usually feed on shrimps which are kept in brine in a desalted condition. But these are only substitutes for what does jelly fish eat in the oceans and seas, and they may not provide them with the nutrition equal to their underwater food.
The jelly fish does eat anything that humans feed on, but human beings in many parts of the world include the jelly fish as part of their diet. There are many people wondering can you eat jelly fish, but there is no exact answer to this question.
Till recently the jelly fish was not considered to be a part of the human diet but some species have got into the menus of the different cuisines in some parts of the world.

Jellyfish is a delicacy in Japan and other countries across the globe. Because of this, major developments in its market industry have been advanced. Jellyfish facts are that it is prevented from going bad by drying it. While wet, it rots after very few hours. However, dried options can still be used for the delicacy after many weeks.
In relation to other species in the fish family, their feeding habit is very different. It normally stings a prey and after the prey is paralyzed, it uses its tentacles to bring the food into its mouth. Although there is no specific prey that can be associated to jellyfish, the most often used prey includes small fish and aquatic planktons although this depends on the size of the species in question. Humans are the worst enemies of this creature. The stinger serves the purpose of keeping off enemies as well as stinging them.
Jellyfish facts say that they lack brains, heart, bones and eyes. You should also know that it can process and interpret some stimuli irrespective of the lack of brains. This is mysterious as that is usually a preserve of brain’s work. Despite their lack of eyes, jellyfish can also sense light impulses through untrue eyesight. The nervous system that it has can only detect a prey or an enemy and this helps it to protect itself either by hiding or attacking.
Furthermore, its body is more than 95 per cent water. Not just that, it is considered as one of the oldest aquatic creature by having existed for more than 650 million years. Even sharks and dinosaurs have not managed this duration. Jellyfish facts are that they are marine creatures and are found in virtually all the oceans in the world. Only a special species of jelly fish lives in fresh water and is not scientifically categorized as a jelly fish. Amazingly, sea wasp also called box jellyfish kills more humans than it does to other aquatic creatures every year. The largest measured about eight feet in diameter. This is equivalent to two and half meters.
They can grow up to a length of 120 feet and the tentacles can grow to be almost equal in length to a half of a soccer pitch. More jellyfish facts include that they grow through many lifecycles giving them ability to reproduce both sexually and asexually at various cycles. They grow through phases like planula which is the larva stage. These get attached onto a surface where they grow into polyps and then later into medusa.

The Irukandji Jellyfish is a small but venomous and dangerous Jellyfish. With its size only one cubic centimeter and found exclusively in the marine waters off the coast of Australia, just north of Cairns, in Queensland. There are two types of Irukandji Jellyfish, Carukia Barnesi and Malo Kingi. Collectively they are responsible for Irukandji syndrome, first documented in 1952 by Hugo Flecker and named after the native Irukandkji people of the region. Carukia Barnesi, the first species of Irukandji Jellyfish was discovered in 1964 by Dr. Jack Barnes, who, wanting to prove this tiny Jellyfish was responsible for the Irukandji syndrome, stung himself, a lifeguard and his son.
The Irukandji Jellyfish has four tentacles that can range from a few centimeters in length to around 35 centimeters. The stingers are grouped in clumps and look like rings made up of small red dots around the bell of the jellyfish, and also along the tentacles. Since the Irukandji Jellyfish is too tiny and fragile to handle and contain, very little research has been done. However, it is known that its venom is a hundred times more potent than that of a cobra, and a thousand times as much as that of a tarantula. What ever research has been done, has confirmed that the potency of its venom allows it to stun its prey (like fast and small fish) very fast.
The Irukandji is cover in millions of microscopic singers, responsible for the venom release. To understand how these stingers work, you can imagine a long inside out sock, coiled along the lines of a spring. Someone unlucky enough to come in contact with the Jellyfish by touch will cause an uncoiling of the spring latching the stingers into the skin like barbs. When the victim pulls away the stingers are ripped from the Jellyfish’s body and remain embedded in the victim. The Irukandji has the unique ability to ‘fire’ the stingers from it’s tips and inject the venom, a unique phenomenon.
Burning on the area of contact, drop in blood pressure and heart rate, sweating, severe and intensely pain muscle cramps in the arms, legs, back and kidneys are some of the Symptoms of Irukandji Syndrome, a very painful and unpleasant experience. Ocean explorers beware, the Irukandji Jellyfish!
An individual recently stung by the Irukandji will notice symptoms within 4 – 30 hours which may take up to 2 weeks to completely be resolved. Pain management is the only treatment for the Irukandji sting as there is no known anti-venom. Patients have been known to experience pain so intensely that they beg the doctor for death. The best way to avoid the sting is to avoid the Jellyfish. Be mindful of the conditions, seasons and areas you are swimming or diving. Divers beware, the Irukandji Jellyfish!

While diving, it is important to be aware of the environment, your body placement and equipment in use. A lot of damage to coral reefs can be done unintentionally by hitting the corals or dragging equipment, spending a bit more time to become aware of your surroundings and also swimming with care and grace will reduce the opportunities for this. Coral is very fragile and can be damaged when knocked about, the coral is also very slow growing, so to hit accidentally, knocking bits off it takes time to grow again, causing long-term damage to corals.
At all times, you should be aware of and respect of aquatic life around you. sea life can become very anxious when interfered, avoid touching, feeding and handling creatures, as this can disrupt the feeding and mating behaviour of these animals. Many marine creatures pose no threat to humans, so be sure not to cause stress for them.
It is recommended to avoid the collection of souvenirs, and other objects underwater. Areas may be very quickly destroyed because of the collection of corals and shells, etc. In popular destinations, it will lead to areas known for their beauty, to become very limited and damaged. If you appreciate the beauty of the underwater world, leave it that way for others to enjoy and take your camera diving and capture the beauty and respect the environment instead.
If you notice any damage or destruction while you dive, you must report it. This could be something from strange substances in water to seeing a shoal of injured/ deformed fish in the region. If you are unsure about whom to report it ,then please let a local dive centre know and they will contact the organization necessary for example, environmental officials and other Authorities. This could prevent further destruction, and even save many lives; even small changes are worth relaying to the necessary authorities.
You should always be a role model for other divers if you appreciate the beauty of the ocean, you must also respect and help keep it clean, if everyone did that, we will be able to see beauty for many centuries now. Being a role model is important because people will notice your good attitude and respect for the sea, they should follow, especially divers, because they can witness for themselves the damage already caused.
For those that are interested in helping the environment and sealife conservation check out Phi Phi Dive Camp, they have many projects currently running in order to protect the sea life and corals in Thailand. As well as conservation you can also look at Diving Phi Phi

The Lion’s Mane jellyfish has the distinction of being the largest jellyfish known to man. The largest specimen on record had a bell shaped body with a diameter of 7 feet 6 inches and its tentacles were 120 feet long. It was definitely longer than a blue whale and is considered to be the longest animal known to the world.
The Lion’s mane jellyfish prefers the cold waters of the North Atlantic, Arctic and North Pacific oceans but similar jellyfish to the Lion’s Mange can be found just outside the waters of New Zealand and Australia. It is curious in that they are rarely found south of 42 degrees north latitude.
Although huge Lion’s Mane jellyfish, with bells as large as 8 feet, can be found in the colder waters, generally the size of Lion’s Mane jellyfish varies. Some of the Lion’s Mane found in Southern waters are a fair amount smaller. Lion’s mane jellyfish tentacles can be 90 feet or even longer. Grouped in clusters of 8, with more then 100 tentacles per cluster, the Lion’s mane sticky tentacles around arrange in a series of rows. Despite it’s large size, the Lion’s Mane jellyfish is not too dangerous, it’s sting isn’t fatal and only causes temporary pain and redness.
The bell shaped body of the Lion’s Mane jellyfish has eight divisions, or lobes, that make it look like an eight pointed star. A complicated arrangement of its colorful arms radiate from the bell’s center which are shorter than the thinner tentacles which come out of the bell’s subumbrella. Size has a lot to do with the colors of the Lion’s Mane jellyfish – smaller specimens tend to be a light orange or tan, while the larger specimens range from a bright crimson to a darker purple.
The Lion’s Mane jellyfish is a coldwater species and can’t really handle warmer water. The jellyfish have a life span of one year and prefer to settle in sheltered bays that are shallow, as they approach the end of their life span. They live on zoo plankton, moon jellies, small fish and ctenophores. Out in open waters, the Lion’s Mane provides shelter and food for species like Medusa fish, Harvest fish, Butter fish, juvenile Prow fish and Shrimps, who treat it like a floating oasis. The predators of the Lion’s Mane jellyfish include other species of jellyfish, sea turtles, larger fish and sea birds.

Years ago, photo editing was a laborious and tedious process. If you wanted to change more than the bare basics, such as lighting or darkening a photo, you could figure on many hours of work ahead of you.
If you had to paint away a feature you would have to make an entirely new picture and cut the object bit by bit into the new image. For instance, if you had a group picture and you wanted to ‘remove’ one of the group members, this could take days.
Now, computer programs like Photoshop make it quick and easy to edit photographs. This is a huge difference in the world of photo editing. Now it is easy to play with lighting and exposure.
It’s also now much easier to change the picture entirely. This can be very unfortunate. You can now take an image and, without a lot of difficulty, take out elements or add elements that were not there when the photo was taken.
This brings up a sticky point, where photojournalism is concerned. Journalists, including photojournalists, are supposed to accurately present what happened. There is a difference between correcting the color cast of a picture, and changing a dull sky to a dark and stunning sunset.
Think about it. You would not deny that putting a celebrity’s head on someone else’s body is a form of dishonesty. By that same token, changing an image to make it more “dramatic” by adding smoke, or by adding people to a crowd scene, is also very dishonest and is not appropriate in journalism.
Some would argue that there is a fine line between changing for editorial reasons and going too far. The two may be close at times but the bottom line is, the picture’s content must not have been changed. If there has been anything added to or taken from the photo in a way that changes the meaning of the image, the photographer has gone too far.
When you are editing photos, you should keep these standards in mind. How closely you need to adhere to them depends on your role. A picture that is “art” can be stylized, because the photographer is an artist. The artist has full artistic license. But a journalist is a journalist, and has journalistic standards, even when their medium is photography.
Aside from journalism, the writer additionally frequently gives advice on silver charm bracelets and charms for charm bracelets.

A surgeon’s set of before and after photos is often very revealing of both a surgeon’s skills and the cosmetic procedure you are about to undergo. Oftentimes, cosmetic plastic surgery photo viewing will be a contributory factor that will help you decide to undergo a procedure or not.
Always Ask for Photos
It’s always advisable to know much about the procedure before you undergo one. A plastic surgery photo viewing session is one of the best ways for you to get a glimpse of a surgeon’s sense of professionalism and skills and how you might just look like after surgery.
It would be better though if you do not settle for just one plastic surgery photo. Ask your surgeon to present a gallery and explain to you which plastic surgery photo is most likely reflective of your condition and goals. You might also want to log on to websites and scour the net for numerous other photos. This will help you compare your surgeon’s work with that of others.
Assess Photo Quality
A good plastic surgeon would always have well shot plastic surgery photo galleries. Badly done photographs may be a sign that you may not have a very dedicated and meticulous surgeon. Make sure that you are viewing a high resolution plastic surgery photo gallery. Pictures however that appear too perfect are something to be wary of. Cosmetic plastic surgery cannot produce perfect results and you should be on your guard if all the pictures present fabulous looking models.
Look for Signs of Editing and Manipulation
Of course reputable and accredited surgeons do no more than cover a patient’s identity during minor plastic surgery photo editing. None of the surgical details are masked. It is still a good idea however to have a discriminating eye. You might end up in the hands of the rare surgeon con artist who might resort to plastic surgery photo editing.
Check also the galleries’ lighting and angular inconsistencies. Before photo editing software was invented, clever photographers used lighting and angles to change the look of the same object. Some surgeons may not have intentionally employed such a practice. Real lighting difficulties may truly have resulted in a picture that looks better than the actual result. Simply ask your doctor about what you see if you notice differences in lighting or angle in before and after pictures.
Do Not Rely On Pictures
Don’t rely on photos alone to make your decision. You might be able to make a more informed decision if you requested for a computer assisted display of what you would look like after the procedure. You should also consider looking for real people you know such as friends and family and assess for yourself how much they have improved in their appearance.
The best factor to look into however other than pictures is a doctor’s accreditation or board certification. Researching about a doctor’s qualifications is the best way to ensure safety.

I still remember when I first saw an ad in a technology magazine for something called a Digital Video Recorder. I thought to myself, this will never work, how on Earth can you manage to store hours of films on something called a hard drive? It just seemed that tapes and cassettes were always going to be around.
Great idea I remember thinking to myself. No more running out of tapes all the time, no more having to fish around with fast forward and rewind options to try to find the program that I wanted to watch.
The ad went on to say that you could even record programs on the hard drive when you were not even at home. You could automatically program the Digital Video recorder to do this, and the quality of the recorded picture was much better than on a tape cassette.
But as the first Digital Video Recorders were selling for about $1000.00 at the time, it was hard to find that kind of money. But after a year or two the price did drop, and I bought my very first DVR, and the only thing that did bother me was the fact that you could only update your TV listings by ringing up for them.
But I must admit that was the only thing that did not impress me at the time; it was certainly a lot better than my Video Tape Recorder of the time.
Technology has moved on even further since its first inception, and a DVR can now hold even more programs than before.
Funnily enough it seems a long time ago when the DVR was first introduced, but it was not that long ago really. But just like more recent inventions such as the cell phone it is hard to imagine life without my DVR.
This is probably one of the best ideas in recent years, and I for one am glad to have a DVR in my house.
