Jellyfish sting: The injection into the skin of venom from the stinging unit (the nematocyst) of the jellyfish.

The jellyfish tentacles can extend for several feet and are lined with venom-filled cells (nematocysts). One tentacle may fire thousands of nematocysts into the skin on contact. On contact, each cell fires a barbed thread that penetrates the victim's skin. Jellyfish belong to several different classes of invertebrates:

* Hydrozoans (for example, the Portuguese man-of-war and fire corals)

* Scyphozoans, the �true� jellyfish and most common type

* Cubozoans, for example the most toxic �box jellyfish�

* Anthrozoans (sea anemones and corals, which are related to jellyfish but only minimally poisonous to humans)

Symptoms of a jellyfish sting can vary depending upon the type and location of the sting. The pain can be severe, particularly in the first hours after an attack, and itching is common. There may be weakness, nausea, headache, muscle pain and spasms, lacrimation (tearing) and nasal discharge, increased perspiration, changes in pulse rate, and chest pain. Welting may persist for weeks at the site and scarring may remain.

Stings from true jellyfish (scyphozoans) are generally less toxic than those of the hydrozoans and cubozoans and usually result in injury only to the parts of the skin where contact with the tentacles occurred. The sting of the Portuguese man-of-war is more painful than that of the common jellyfish, and this sting has been responsible for two reported deaths. Even detached tentacles of these animals are capable of causing stings to humans for up to two weeks. Allergic reactions to jellyfish stings sometimes occur that further increase the inflammation and severity of the wounds.

Stings from box jellyfish (cubozoans) are the most dangerous type of jellyfish sting. The box jellyfish found in Australian waters has venom so deadly that it may cause cardiovascular collapse along with respiratory and neuromuscular paralysis that can kill an adult within minutes. Poisonings by the box jellyfish of Australia require the administration of an antivenom, which reverses the effect of the poison. Those swimming in Australia or other areas where box jellyfish may be found should always seek emergency medical evaluation when stung by a jellyfish.

If you are stung by a jellyfish, always remove any tentacles that are adherent to the skin using gloves or forceps. Application of household vinegar (5% acetic acid) will inactivate any undischarged stingers and lessen the severity of the symptoms. Over-the-counter pain relievers should be started immediately for minor stings. Narcotics may be needed for severe pain. Serious stings may require oxygen or cardiorespiratory assistance. IV fluids and epinephrine may be needed if shock develops. Always seek emergency medical care if you are stung by a jellyfish and you become severely ill, have difficulty breathing or swallowing, or develop severe pain following the sting.

How do Jellyfish Reproduce?

The jellyfish is one of the most mesmerizing creatures of the marine land. They have a fascinating aspect to their life cycle, which is their process of reproduction. The process of reproduction in a jellyfish involves a number of different stages and the jellyfish passes through a number of different forms before it develops into the easily recognizable adult form in the last stage of the reproduction cycle. On the other hand, the different stages of reproduction in a jellyfish involve both the sexual and the asexual from of reproduction. Let's look at the reproduction cycle of the jellyfish to understand this fascinating process.

Fertilization: jellyfish do not have any specialized bodily system for reproduction. The male jellyfish releases its sperm in the water. The female carries her eggs in her mouth or stomach. When the sperm that are released in the water come in contact with the female's eggs, they get fertilized. In the embryonic stage, these fertilized eggs are stored in brooding pouches along the oral arms of the female or in her stomach.

Planula Larvae: After the embryonic stage is over, the larvae get transformed into tiny planulae that are free swimming and they detach themselves from their mother's body. At this stage, the jellyfish looks an oval shape and has tiny hair along its body that act like multiple oars to facilitate movement. However, these are not very effective, and the planulae float for a few days in the tides and currents of the water. At this stage, they start sinking towards the deep end of the ocean until they attach themselves to a hard surface and the next stage in their reproduction cycle begins.

Polyps: Once the planula has found a hard surface, it attaches itself to it at its base. On the other end of the planula is its mouth which is surrounded by a few tentacles which help in procuring food and transport it to the planula's mouth. At this stage, this planula becomes a polyp and begins the most sessile stage of its life. It remains attached to the surface, and over time a new polyp gets formed from the trunk of the first polyp. This process is repeated innumerable times, until an entire colony of polyps is formed. The polyps of this colony are all connected to each other with small feeding tubes. This ensures that every polyp receives adequate nutrition irrespective of its place in the colony. This stage of jellyfish reproduction can last for years and the polyp colony can grow up to a tremendous size.

Ephyra: When conditions are right, this colony of polyps begins to transform itself. Horizontal grooves appear on the outside of the colony. The topmost groove, which matures the fastest, then detaches itself from the colony and becomes a free swimming tiny jellyfish known as ephyra.

Medusa: This is the last stage of the jellyfish reproduction cycle and the most recognized. The ephyra stage gives to the medusa stage where the tiny jellyfish grows into an adult and has a fully formed body and its distinct shape.

Hope I helped! :)

Best Answer?

will God judge Jellyfish on Judgement Day if it stings you and you say `Yo, I have dominion over the animals`?

The jellyfish won't care. They're badass, above the law! Nothing can beat the jellyfish. Pure evil, making corals and stuff, and stinging people. What a jellyfish thinks: like a boss.
