The Mediterranean box jellyfish, on the other hand, is a stinging jellyfish that may deliver a nasty, but non-lethal, sting. Although it is not a widespread species in the Mediterranean Sea, it has been found in a few locations in recent decades. The first recorded sighting of a Mediterranean box jellyfish was in 1995, when two fishermen were stung by stranded specimens off the coast of Malta.
Since then, they have been reported from several other countries in Europe and North Africa. It is likely that this jellyfish only appears in limited areas due to its need for warm waters and high levels of sunlight. Its absence from many regions where these conditions exist suggests that it is probably not widely distributed throughout the Mediterranean.
Although rarely fatal, if you are stung by a Mediterranean box jellyfish you should seek medical attention immediately because of the risk of developing a life-threatening allergic reaction. The best way to avoid being stung is by avoiding coming into contact with this jellyfish. However, if you are forced to come into contact with it, wearing protective clothing will help prevent an injury from occurring. Jellyfish can also be prevented from stranding by not overfishing their food source (which is mostly fish).
The majority of jellyfish stings occur in tropical and warm seas. Most jellyfish around the South Carolina coast cause very slight discomfort with their stings. Although most jellyfish in South Carolina waterways are safe for people, there are a handful that should be avoided. Keep an eye out for warning signs and take necessary precautions if you come into contact with any jellyfish.
Jellyfish are members of the class Cnidaria. There are five main types of jellyfish: cubozoa, cyanea, hydromedusae, pteria, and tailed jellyfish. Of these, only tailed jellyfish commonly appear in South Carolina waters. The other types can be found worldwide and include organisms that contain calcium carbonate as their main component (jellyfish are actually colloids containing mostly water).
Jellyfish are related to sea anemones and corals but are not part of those groups. They derive their name from their gelatinous texture. Jellyfish have no bones or muscles and contain within their body fluids many small animals such as bacteria, algae, and parasites. As long as they remain submerged in ocean water, jellyfish will continue to swim around and search for food. If they are stranded on shore or become trapped in shallow water, they will eventually sink to the bottom and decompose.
People sometimes get jellyfish stuck in their hair after swimming in coastal waters.
Jellyfish are prevalent in Cyprus, however they are not always present. Tentacles trail down from the body of many jellyfish and into the sea. The tentacles contain stinging cells known as nematocysts, which contain small harpoons and venom. If one of these come into contact with a fish or a human, the fish will die and the jellyfish continues its journey through ocean waters looking for more prey.
Cyprus has very warm water most of the time. This means that jellyfish can thrive here year round. There are two main types of jellyfish that can be found in Cyprus's waters: box jellyfish and sea nettles.
Box jellyfish are transparent with a pale yellow color inside. They have eight long black legs on each side of their body and an oval-shaped head with no mouth or eyes. The bell of the box jellyfish only measures about 1 to 2 feet (30 cm to 60 cm) across but it can reach up to 10 feet (3 m) tall when fully extended. An average-size box jellyfish can weigh up to 450 pounds (200 kg).
Sea nettles are brownish red in color with white markings. They have six thin black legs and a small tube-like proboscis that hangs below their bell. When threatened, the sea nettle raises its tentacles above its head like a curtain.
Jellyfish, which are gelatinous sea organisms, swim freely in the Mediterranean and are typically friendly. The Mauve Stinger is the most well-known in Malta (Pelagia noctiluca). They are usually discovered at the surface of the ocean during low light conditions or after washing ashore on the beach. The stinging cells of the Jellyfish are located under its skin and break through when it comes into contact with water. This causes the Jelly to fluoresce like a luminous creature in darkness.
There have been reports of people being stung by Jellyfish in Malta but this happens very rarely. If you are bitten by a Jellyfish then get out into open water as soon as possible to reduce your exposure to more jellyfish. Jellyfish can also swim away so try not to chase them!
People sometimes think that if they walk on the beach at night without shoes that they won't be hurt by the Stingers but this is not true. The Mauve Stinger lives in shallow waters near beaches and uses its tentacles to catch prey. It doesn't make sense to expose yourself to danger by walking on the shoreline without shoes when there are better options out in the sea!
The best thing to do if you find yourself in close proximity to a Jellyfish is to keep moving so that it cannot sting you again.
While box jellyfish may be found in warm coastal seas all over the world, dangerous forms are mostly found in the Indo-Pacific area and northern Australia. This contains the most poisonous marine species, the Australian box jellyfish (Chironex fleckeri).
Other names for this jellyfish are fairy ring jellyfish, fairy whip, fairy hand, fairy finger, sea wasp, ocean wasp, and wandoo jellyfish.
Fairy ring jellyfish can reach a height of about 1 m and weigh up to 20 kg. The umbrella-shaped body has a large central disk and eight slender stinging tentacles that grow out of it. The tentacles are very flexible but contain barbs that prevent them from being pulled back into the jellyfish after they have been stretched out by waves or caught by the wind. The whole organism is surrounded by a sticky mass of glycoproteins called acryloid which helps it attach itself to surfaces. The jellyfish feeds on bacteria which live in the water column and die after releasing their nutrients into its environment. Fairy ring jellyfish are found in oceans around the world at depths down to 200 m, except in polar regions where there are no tides or currents strong enough to push them ashore.
Box jellyfish are less abundant but more deadly than fairy ring jellyfish. They can grow taller than 3 m and weigh up to 100 kg.
