Facts to Know of Jellyfish

A very common type of fish found in almost all the seas and oceans present on the face of this earth is the Jelly fish. There are different types of jellyfish and each of them is known by different biological names. The Jelly fish found not only in seas but also in fresh water which is very deep. The fresh water jelly fish is usually very small -sized and are colorless.

The habitat of the jellyfish will depend on the types of jellyfish. Some species are known to be present in warm waters and some others are found in the frigid and cold waters of the North Pacific Ocean. The Moon Jelly also known as the Aurelia Aurita is one of the regular types of jelly fish which is shaped like a saucer having a bell and is nearly transparent. Though the Moon Jelly is not known to be fatal it may sometimes have a deadly sting and this is the species that is generally seen in various aquariums.

One of the other types of jelly fish is the’ Physalia Physalis’ that is a commonly called the Portuguese Man Of War. Though it does not actually belong to the species of jelly fish it is considered to be one. The unique feature of this fish is that it has four polyps that combine to form the body of the fish but its functions are all very different. The fish does not have a fatal sting, but it can induce severe pain accompanied with fever and rashes.

There are many other jelly fish species that can be quite dangerous too. If you go by some of the deadly jellyfish facts it is surprising to note that even a fish can be highly harmful and fatal to humans. The Lion’s Mane or the Winter Jelly fish which is known scientifically as the ‘Cyanea capillat’ is more commonly seen in frigid waters. Its sting is quite mild and not too painful though rashes can be caused.

There are many such deadly jelly fish facts that some of the more dangerous types of jelly fish have but in general they are considered to be very docile and do not attack unless instigated. With more than 1500 species that have been identified by scientists the jelly fish is very unique in its looks as well as its habits.

Watch Out For The Tiny But Fatal Irukandji Jellyfish!

The Irukandji Jellyfish is really tiny but fatally venomous – it is just one cubic centimeter. It is found in the marine waters around Australia. The symptoms are known as the Irukandji Syndrome. There are two kinds of Irukandji Jellyfish – Malo Kingi and Carukia Barnesi. Hugo Flecker first documented the symptoms of the Irukandji Syndrome in 1952 – named after the Irukandji folk who inhabited the coastal strip tat lies north of Cairns in Queensland. Carukia Barnesi was the first species to be identified by Dr. Jack Barnes in 1964. Dr. Barnes, wanting to prove that this jellyfish had caused these symptoms, got himself to be stung by it, along with his son and a life guard.

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!
