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!

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.
