Strange New Jellyfish Like Nothing Else

in  Sea

Sporting a reproductive “skyline,” a new species of jellyfish is like nothing else known under the sea, a new study says. Shaped like flying saucers, both males and females of the new jellyfish have gonads on the outsides of their bodies, unlike any of the approximately 3,000 other jellyfish species known to science­. Gonads are the reproductive glands that produce sperm in males and eggs in females. Arranged in a “crater” at the center of the jellyfish’s top side, the gonads, upon close inspection, resemble “skyscrapers in a downtown business district,” said Lisa-Ann Gershwin, curator of zoology at the Queen Victoria Museum and Art Gallery in Launceston, Australia. Accordingly, Gershwin gave the jellyfish the species name “medeopolis,” Latin for “city of gonads.” “It’s just so completely different from anything we’ve ever seen before,” Gershwin said—in fact, the jellyfish has forced the creation of a whole new family and genus, Csiromedusidae and Csiromedusa, respectively. Both names honor the Australian government’s Commonwealth Scientific and Industrial Research Organization (CSIRO), which assisted the scientists with their research. (Related: “New Jellyfish Species Found.”) “City of Gonads” Stumps Scientist Gershwin and colleagues discovered the city-of-gonads jellyfish eight years ago in a part-seawater river in the city of Hobart (map) on the Australian island of Tasmania. It took until now, though, for the scientists to verify that Csiromedusa medeopolis represents a new family. (Also see “Blue Jellyfish Invade Australia Beaches.”) Harmless to humans, the new jellyfish species measures just 0.06 to 0.08 inch across—”not the smallest ever known, but it would be pretty close,” Gershwin said. About 90 percent of jellyfish species are smaller than an inch, but fewer than 0.5 percent of jellyfish are measured in millimeters. Making the Csiromedusa medeopolis discovery was “like a day at Disneyland for a scientist,” said Gershwin, who’s named more than 160 new jellyfish species, including a “rainbow glow” jelly (picture). Despite all that experience, she’s at a loss to explain what good external gonads would be for a jellyfish. “I’ve thought about this for so long — I have no idea,” Gershwin said. “There may be some functional reason, but I can’t see what it is.” The city-of-gonads jellyfish study is published online this week in the journal Zootaxa.

Space caramel made from giant jellyfish
16 Sep 2009

In the latest move in Japan’s war on giant jellyfish, high school students in the town of Obama have developed a new type of caramel candy made from the enormous sea creatures — and they are offering it up as a snack for astronauts in space.

The enterprising Obama Fisheries High School students have requested the Japan Aerospace Exploration Agency (JAXA) to place their chewy treat on the official menu for astronauts aboard the International Space Station. The space agency, which appears to be entertaining the proposal, is reportedly sending a representative to the school tomorrow (September 17) to evaluate the candy.

Described as having a sweet and salty flavor, the caramel’s ingredients include sugar, starch syrup, and jellyfish powder, which is obtained by boiling the jellyfish down to a thick paste, drying it, and grinding it into fine particles. The most recent batch of caramel uses powder from Nomura’s jellyfish snared last month in fixed fishing nets in nearby Wakasa Bay. The bay is located in Fukui prefecture, which has been among the areas hardest hit by the giant jellyfish swarms in recent years. The students began cooking with Nomura’s jellyfish three years ago, after a NASA-designed food safety management system was installed at the school. In 2006, after the school developed a method for processing giant jellyfish into an edible powder, a local company began using it as an ingredient in their jellyfish cookies.

Since then, the students have been searching for new ways to use their jellyfish powder. They are hoping to benefit from the recent raw caramel craze. sweeping Japan.

How to treat a Jellyfish sting

Contrary to popular belief, you should never urinate on a jellyfish sting. This will just make the problem worse, as does washing the sting with fresh water without prior treatment. You should also not try to put ice on it before properly treating the area, which is sometimes people’s initial inclination to try to take away some of the pain and swelling. If you put ice on it, what you’ll actually do is make it worse, which can be serious business in some cases, even causing death, depending on what you were stung by, the extent/location of the sting, and your age (elderly folk and children are much more susceptible to extreme reactions to jelly stings).

Before I get into how to treat a jellyfish sting, it’s first important to understand how jellyfish stings work. Jellyfish sting you through nematocysts which are released from their tentacles. Nematocysts are tiny spine covered tubules. The spines anchor themselves in your skin and when the nematocysts fire, various chemicals are injected into you. In some cases, you may have thousands of these nematocysts attached to your skin after coming in contact with a jellyfish tentacle, not all of which may fire right away.

When you pee on the sting or try to rinse it with fresh water this changes the tonicity, which in turn can cause the nematocysts to fire, injecting you with even more of the cocktail of chemicals, hence why you shouldn’t do this.

Irukandji are tiny jellyfish, usually not more than 1 cubic centimeter in size, that can be found in the ocean near Australia

While in most cases, jellyfish stings aren’t life threatening, they absolutely can be. If you happen to know your jellies and you know the sting is from an Irukandji or a box jellyfish, you’ll want to call for emergency medical aid right away. In extreme cases, box jellyfish stings have been known to kill people in a matter of minutes and anti-venom is needed to stave off the worst of the symptoms, so you’ll not want to wait around to see how the person’s body reacts first. Also, if the sting covers a large area, for instance more than half of an arm or a leg, or is on the face or genitals, it’s generally a good idea to call for emergency medical aid.

Box Jellyfish, not surprisingly can be recognized by its somewhat cubic shape, rather than domed. They also can move quite fast, as much as 5 mph, rather than just floating along as most jellies do.

  1. In other cases, watch for signs of difficulty breathing, chest pain, difficulty swallowing, the person’s voice changing, loss of consciousness (easiest to spot!), hives, dizziness, irregular heartbeat or other heart symptoms, sudden weakness, nausea, or muscle spasms. If these signs start to pop up at all or if the person stung is a child or an elderly person, call for emergency medical aid right away.
  2. So now that you’ve either called for medical aid or not depending on the severity of the sting or what did the stinging, how you should treat a jellyfish sting is, first, if a tentacle is still attached, you can choose to either try to remove it immediately or try to deactivate the nematocysts first using the method in the next step, making sure the person stung holds very still while either is being done. Some guides recommend removing the tentacle first and others say treat the area first. I’m inclined to go with the first as the tentacle can continue to impart additional nematocysts to the area the longer you’re attempting to treat it, which is particularly serious if you’re alone and having to move around and treat yourself, which will pretty well assure the tentacle will be releasing more nematocysts on you as you move.
  3. To remove the tentacle, use gloves, thick clothing, tweezers, sticks, or the like to very gently detach it from the person being stung. Basically, just don’t touch the tentacle with your bare skin and try to minimize its movement on the skin of the person being stung. Also, keep in mind that the nematocysts can stick to your glove or clothing, so after removing the tentacle, you’ll want to throw away the item that came in contact with it to avoid accidentally stinging yourself later.
  4. In order to deactivate the nematocysts, pour vinegar on the area stung for at least 30 seconds, and then, if possible, soak the area for as much as 30 minutes in vinegar. The acidity of vinegar should neutralize some or all of the unfired nematocysts, specifically neutralizing some of the proteins in the cocktail they shoot into you (though not all types of jelly stings use the same cocktail, so vinegar won’t always work).
  5. Now, it should be noted here that you should not put vinegar directly in your eye, so if an eyeball was stung, instead use a saline solution, such as Artificial Tears, to thoroughly rinse the eye. If the sting is inside your mouth, gargle and swish around in your mouth a solution of 1 part vinegar to 3 parts water, then spit it out (don’t swallow!). Repeat this step a few times.
  6. Portuguese Man o’ War, which isn’t technically a jellyfish, simply jellyfish-like
  7. Also, if you were stung by a Man o’ War, vinegar will make their stings worse, so don’t use it in this case, instead, use the next solution.
  8. If no vinegar is available, rinsing the sting in a baking soda / sea water (only if it’s salt water, no fresh water) mixture and then gently apply a baking soda / sea water paste to the area should also neutralize the nematocysts. If baking soda isn’t available, rinsing with sea water works too, just not as well.
  9. Next, use a knife, shaving razor, credit card, etc. to very gently “shave” the area stung (don’t use very much pressure or it may cause any non-neutralized nematocysts to fire) to get rid of any remaining nematocysts. Some guides also recommend gently applying shaving cream or soap lather before shaving the nematocysts off.
  10. Once you’re done shaving the area, re-apply the vinegar or salt water solutions.
  11. Finally, dry the area off as best you can without using too much pressure. Taking an antihistamine, such as Benadryl, or applying a hydrocortisone cream to the area will help reduce itching and swelling.

In the aftermath, make sure to clean any open sores a few times per day with some type of antibiotic ointment. Most of the pain from the sting should begin to dissipate within 5-10 minutes of treating it and within 24 hours much of the pain should be gone. After the nematocysts are removed, ice-packs can help somewhat with the pain and swelling. However, don’t put the ice packs on before you’re quite sure you’ve gotten rid of the nematocysts.

THE Most Dangerous Jellyfish

Make no mistake the following facts are true DON’T try them.

The infamous box jellyfish developed its frighteningly powerful venom to instantly stun or kill prey, like fish and shrimp, so their struggle to escape wouldn’t damage its delicate tentacles.

Their venom is considered to be among the most deadly in the world, containing toxins that attack the heart, nervous system, and skin cells. It is so overpoweringly painful, human victims have been known to go into shock and drown or die of heart failure before even reaching shore. Survivors can experience considerable pain for weeks and often have significant scarring where the tentacles made contact.

Box jellies, also called sea wasps and marine stingers, live primarily in coastal waters off Northern Australia and throughout the Indo-Pacific. They are pale blue and transparent in color and get their name from the cube-like shape of their bell. Up to 15 tentacles grow from each corner of the bell and can reach 10 feet (3 meters) in length. Each tentacle has about 5,000 stinging cells, which are triggered not by touch but by the presence of a chemical on the outer layer of its prey.

Box jellies are highly advanced among jellyfish. They have developed the ability to move rather than just drift, jetting at up to four knots through the water. They also have eyes grouped in clusters of six on the four sides of their bell. Each cluster includes a pair of eyes with a sophisticated lens, retina, iris and cornea, although without a central nervous system, scientists aren’t sure how they process what they see.
