Jellyfish facts…Everything you need to know…

Jellyfish are categorized due to their characteristics. The different species of jellyfish are the Red Type which is also known as the ‘China type’ can be identified as Rhopilema esculentum. These jellyfish are slightly reddish with a 12-24 inch diameter smooth umbrella.

The jellyfish is a popular seafood in eastern and southern Asian nations where there is a high market demand that stimulates large-scale jellyfish production. Due to its economic importance in China, many biological studies have focused on the jellyfish Rhopilema esculentum Kishinouye in terms of the environmental impact of aquaculture activities and culture techniques. In recent years, the commercial aquaculture of R. esculentum has expanded greatly in China

New jellyfish species discovered on Gold Coast..Australia

ABC News Gold Coast  

A curious child from Paradise Point is responsible for the discovery of a new species of box jellyfish found in a local canal.  Nine-year-old Saxon Thomas found the new species when fishing in his backyard canal.  Scientists have now confirmed the jellyfish is a new scientific discovery.

But Australian Marine Stinger Advisory services director Lisa Gershwin says there is a lot more to learn about it.  “We’re still trying to name it,” Ms Gershwin says.

“I haven’t met Saxon yet but my intention is to one of these days when I meet him ask him what he would like it to be named… I wanna give him the choice to name it because I think it’s such a wonderful thing that here’s these kids out playing with nature and going ‘hey wait, that’s different – what’s that?’ – and now we know. What a fabulous find.”

Queensland Museum’s marine expert Doctor Merrick Ekins has examined the jellyfish.

“A new species is always very exciting. We’ve got a bit more work to do to work out exactly what it is… but it’s definitely in the same family as the box jellyfish. But it’s not THE box jellyfish which is a big relief,” Dr Ekins says.

“The first thing we did was to make sure it wasn’t thechironex fleckeri box jellyfish that’s infamous for killing people, because if that’s suddenly appearing down here on the Sunshine Coast and Gold Coast then that would be a real issue for swimmers.”

However, it is not yet known if this new species is dangerous in its own way.

“We don’t know about that… whether it gives you a sting is most likely. It’s probably not life threatening but we don’t know.”

Red Sea Fire Urchin…

Asthenosoma marisrubri (‘flexible body of the Red Sea’) aka Red Sea Fire Urchin and Toxic Leather Sea Urchin , is a relatively common sea urchin with a widespread distribution in the Indo-Pacific, and it subsists on a great variety of food including algae, coral polyps and bottom detritus. It is most active at night and is named for the extreme pain inflicted by its spines and its occurrence in the Red Sea.

Stingray Season in Florida..April to October

Stingray season on Florida beaches runs approximately between the months of April and October. (The most popular time for Florida beach vacations. Imagine that.) It is during these months that these sea creatures come into the warmer shallow Florida Gulf Coast waters to mate.

Stingray-kit

They also are lazy and bury themselves in the bottom sand to stay away from being eaten by sharks or other larger rays. Activity and energy frighten these shy sea creatures. They can’t see well and rely on electro-sensors/vibrations to let them know they are in danger. So remember to do the “shuffle” when entering the water or take along an OCS Stingray 1st aid kit if you don’t…

Jellyfish Facts…The “Pink Meanie”

Meet the “pink meanie,” a new species of jellyfish discovered by scientists at Dauphin Island Sea Lab and the University of California, Merced.From Discovery News–On the surface, this brightly colored jellyfish may not appear to be particularly extraordinary. According to DNA and morphological analysis, however, this marine animal, Drymonema larsoni, is not only a new species of jellyfish, but also a new family.

Found in the waters of the Gulf of Mexico and the Caribbean, the pink meanie is the first new scyphozoan family discovered since 1921.

“It’s rare that something like this could escape the notice of scientific research for so long,” Keith Bayha, a scientist at at Dauphin Island Sea Lab, said in a press release. “That it did is partially due to Drymonema‘s extreme rarity almost everywhere in the world.”

Portuguese Man o War…spotted worldwide

The Portuguese Man o’ War  can be found anywhere in the open ocean (especially warm water seas), but they are most commonly found in the tropical and subtropical regions of the Pacific and Indian oceans, and the northern Atlantic Gulf Stream. The Man o’ War has been found as far north as the the northeast end of the Gulf of Maine.

They wash ashore along the northern Gulf of Mexico and the east and west coasts of Florida.  An abundance of Portuguese Man o’ Wars can be found in the waters of Costa Rica, especially in March and April.  They have been spotted recently off the coast of Spain, Ireland, in Welsh waters and in the Mediterranean near Corsica and Malta.

They are also frequently found along the east coast of South Africa, (particularly during winter storms if the wind has been blowing steadily on-shore for several hours), as well as around the Hawaiian Islands.  Strong onshore winds may drive them into bays or onto beaches. It is rare for only a single Portuguese Man o’ War to be found; the discovery of one usually indicates the presence of many as they are usually congregated by currents and winds into groups of thousands. Man o’ Wars typically travel in groups of 1,000-plus.

Ocean Care Solutions Lionfish Sting 1st Aid Kit provides safe and effective sting relief

Pterois volitans and P. miles
Native range: Indo-Pacific and Red Sea
Invasive range: East coast of the United States and Caribbean sea

Some say that the invasion started in Miami, when Hurricane Andrew smashed an aquarium tank in 1992. But you can’t blame the weather: records of wild lionfish in Florida date back at least to 1985. This popular aquarium fish may have been released by fish enthusiasts tired of having a relentless predator in the living rooms, silently dispatching their other fish. And now that exotic predator is spreading north to New England, south to Panama and throughout the Caribbean, feasting on juvenile snapper and grouper along with algae-eating parrotfish as they go–-species which help keep reefs healthy. The lionfish is the first marine fish invasion in the western Atlantic.

Lionfish Range in the US.

Marine biologists are shocked at the speed of their spread in just a decade and at their population densities. Few fish species have established in the wild, let alone so successfully. Suddenly, they’re an abundant reef fish from the Bahamas to Rhode Island. Overfishing of predators like the grouper may be part of the story. Reef destruction and trophic cascade are possible outcomes. The only range limits appear to be colder and fresher waters.

A female lionfish produces two million eggs a year, so not only does it seem unlikely the species can be successfully eradicated, even slowing the growth rate is a challenge. Because lionfish eat just about anything that fits in their mouth while larger native fish don’t seem to recognize lionfish as prey, some experts say humans are the only predators left to call upon.

Common lionfish (Pterois miles)

As of 2010, the Florida Keys National Marine Sanctuary has given out licenses to divers to kill the species inside the property. Reef Environmental Education Foundation (REEF) hosts a series of “Lionfish derbies” offering prize money  largest, smallest, and highest number caught; and publishes the Lionfish Cookbook, aimed at introducing chefs to what NOAA calls a “delicious, delicately flavored fish” similar in taste to snapper and texture to grouper. Lionfish have venomous fin spines––an uncommon feature on East coast species–-making them top predators and a danger to fishermen and divers. (And more expensive than many other fish on the menu, someone has to remove those venomous spines.)

The Lionfish 1st aid kit comes with everything you need to effectively treat your marine sting.

Red sea urchins lining the seafloor can “see”….

Sea urchins may use the entire surfaces of their bodies—from the ends of their “feet” to the tips of their spines—as huge eyes.

Scientists had already known the marine invertebrates react to light without any obvious eye-like structures—raising the question of how the animals see.

Previous genetic analysis of the California purple sea urchin had revealed that the animals possess a large number of genes linked with the development of the retina—the light-sensitive tissue lining the inner eyeball in people and other vertebrates.

This and other research suggested that sea urchin might rely on light-receptor cells randomly scattered across their skin, which collectively function like retinas.

Scientists had theorized the animals’ spines simulate the light-blocking pigmented cells found in most animals’ eyes. Because light-receptor cells in the retina can soak up light from every direction, pigmented cells work to block light from the back and the sides so animals can “see” what’s in front of them.

Now, however, the scientists have found two distinct groups of bristly, light-receptor cells concentrated at the bases and tips of the purple sea urchin’s 1,400-plus tube feet. These long, suction-tipped tubes, located on the undersides of sea urchin bodies, help the organisms move.

The team suspects that sea urchins use their tube feet as retinas and the rest of their bodies to shield against the extra incoming light, said researcher Maria Ina Arnone, a developmental biologist at Anton Dohrn Zoological Station in Naples, Italy.

Prior studies did find the number and placement of spines on a sea urchin could affect how sharp its vision might be, and this new find “might well be part of the picture,” Arnone added.

Australian Bull Ray….Stingray

The Australian bull ray has a disc that is wider than it is long. The snout is blunt with a skirt-shaped inter nasal flap as well as a single fleshy lobe that surrounds the snout and almost reaches the pectoral fins. The medium-sized eyes are located on the sides of the head and the spiracles are large. The pectoral fins which make up the “wings” of this ray originate below the eyes. The margins of the pectoral fins are deeply concave and the tips are highly angular. There is a small dorsal fin that originates over or just behind the pelvic fin rear tips and is anterior to the spine on the tail. The tail is elongate and whip-like and has a venomous stinging spine located just behind the dorsal fin.

Product Review – Jellyfish Sting Relief Solution

About Ocean Care Solutions

Ocean Care Solutions’ (OCS) first aid products were developed by Kevin, a certified scuba diver. Kevin noticed that there was no convenient, proven medically effective, first aid products for stings from the Lionfish, the Man of War, the Sea Urchin, the Stingray, Fire Coral and Jellyfish. For two years Kevin consulted with international marine science and emergency medical communities to develop what they refer to as ‘the definitive Gold Standard’ for sea sting injuries. All OCS’s products have been developed without the reliance of myths, home remedies or guesswork.
Ron at OCS got in contact with Dive Flag App in a hope to have their product reviewed and publicized to Scuba Divers around the world. After initial discussions OCS sent us, here at Dive Flag App, a package containing a few hundred samples to test and distribute to other Dive Flag App members.  Today we had the opportunity to test their most ‘popular’ product the Jellyfish Sting Relief Solution (JSR Solution). This was a timely arrangement as Australia is currently experiencing an outbreak of jellyfish including the Blue Blubber Jellyfish (common name).

Product Description – Jellyfish Sting Relief Solution

OCS’s JSR Solution was developed to neutralize the stinging cells of jellyfish. The solution suspends any remaining pain causing nematocysts (stinging cells) from firing.  The directions of use are as follows:
  1.  Rinse the injury with salt water only,
  2.  Shake the spray and simultaneously press down on the top to pump the solution,
  3.  Apply the safe JSR Solution for 3-5 minutes, and then
  4.  Simply scrape away the pain.  Re-apply if necessary.
The application of the JSR solution is to ‘de-activate’ the jellyfish stinging cells. For the best results it is recommended that you apply the JSR Solution as soon as possible after having been stung. Delay in the use of this product limits effectiveness.
The JSR Solution comes in a small and convenient spray bottle made with medically recommended 5% acetic acid for the best results.

Product Trial

Dive Flag App were naturally skeptical about the effectiveness of OCS’s JSR Solution and so we decided to test the product out. Before reading further it is important to note that Dive Flag App did so under the supervision of trained emergency personnel and in no way is Dive Flag App suggesting that other members perform the following test.
Frank Vorster located two Blue Blubber Jellyfish in the Gold Coast Seaway, Queensland, Australia. He proceeded to sting himself in two ‘similar’ locations by lightly pressing up against the tentacles of the two jellyfish as they floated by. To one location he applied the JSR Solution and to the other he applied nothing. Eager to test the product out – others part-took in the experiment too.

Observations

  1. Within one minute, the stinging sensation on the hand with the JSR Solution started to subside whilst the second location’s continued to intensify as more stinging cells activated.
  2. After five minutes the stinging sensation on the location with the JSR Solution had all but faded completely, whilst the stinging sensation of the second location continued.
  3. Frank wiped the location with the JSR Solution as directed. The location where he had applied the JSR Solution appeared unaffected. Whilst having  wiped off the second location in a similar fashion had only activated the remaining stinging cells, effectively reactivating the sting.
  4. For a further 25 minutes Frank felt the stinging sensation on the second location whilst the location where the JSR Solution was applied felt “like it was never stung”.

Product Review

The JSR Solution performed as OCS had claimed. The product was easy to apply and immediately effective. The quality is guaranteed by OCS’s Californian manufacturing facility. A single 1oz bottle can be used to relieve 4 stings and the 4oz bottle can relieve up to 12 stings. With a shelf life of over 2 years the product can be stored without concern.
  • Price: 5/5
  • Effectiveness: 5/5
  • Quality: 5/5
  • Product Recommendation: Don’t get stung without it! Don’t go diving without it!
Dive Flag App highly recommend that all beach going, water sport activists and especially scuba divers keep a bottle of the solution in their bag. The product is incredible effective and useful.

Where to Buy the Product

Dive Flag App is so impressed with the effectiveness of the solution, we have worked out an arrangement with Ocean Care Solutions to become the exclusive distributor for these products. Dive Flag App is currently developing an on-line store where you can buy the product. If you would like a sample, to purchase some units for personal use or become a retailer for these products, simply email us for more information: info@diveflagapp.com .
