Seasons change but the Portuguese Man o War never do….

As the seasons and winds change in the U.S., the Portuguese Man o War begin to arrive in large numbers.

First of all, there are no real seasons for the Man o War, as such, but because of wind currents associated with season change and weather interruptions, the Man o War is on the leading edge of those winds since it has no propulsion system other than inflating it’s crown with gas and catching the wind.

man o war..beachedTx

What is typically recognized however, is the Man o War are, as a general rule, found along and around the Florida coast lines to Pensacola from late October thru February, the largest concentration generally in Nov and Feb.; the same as Costa Rica from March to May and to some degree the 10th day after every full moon in Hawaii. There is a long history of documenting these events so it is reasonable to believe these expectations every year.

Now, if you were stung by a Man o War, you were stung by an Atlantic Portuguese Man o’ War. There is no jellyfish specie known as a Man o’ War..A MOW is a siphonophore..a colony of 4 organisms..don’t have enough time and space to detail that ..there are 3 species of Man o War but all the same if that makes sense..the Atlantic, the recently acknowledge Pacific and the Blue Bottle Man o War..the Atlantic reported to have the nastiest sting but how would one compare them as all three are very painful. They differ in size with the Atlantic the largest and the blue bottle the smallest but don’t think for an instant that changes how nasty the stings are.

The indications that you have been stung by a Man O’ War are: Stinging, burning, redness, swelling of lymph nodes. You may see long welt lines. In some people sensitive to the Man O’ War venom, there may be severe reactions, including difficulty with breathing and cardiac arrest.

The sting toxin secreted from the tentacles is a neurotoxin about seventy-five percent as powerful as cobra venom. The welts can last for minutes to hours.

Studies on the effectiveness of meat tenderizer, baking soda, papain, or commercial sprays (containing aluminum sulfate and detergents) on nematocyst stings have been contradictory. It’s possible these substances cause further damage.

Jellyfish return to nation’s coast

They’re back!  And we’re not talking hurricanes, though that season is officially underway.  And, no, this is not about sharks, since Discovery’s Shark Week doesn’t start until August.

No, it’s time for the increasingly unpopular annual return of swarms of jellyfish to beaches around the world. Last year they made much of the western Mediterranean unswimmable. A couple of weekend’s ago – the official start of summer — thousands of nasty, golf-ball sized jellyfish washed ashore on Florida’s east coast, stinging beach goers as they arrive. Red and Purple warning flags were posted on beaches from Cocoa Beach to Cape Canaveral.

In large part thanks to the over fishing of big predator fish and warmer ocean waters, jellies are showing up sooner, in bigger numbers and far beyond home territories. For the first time since 2006, the Portuguese Man o War are in numbers along the New England coast particularly the Hamptons.  In Florida they clogged the shallows and took over the wet sand of the beach. Lifeguard stands stocked up with vinegar-and-water solutions to help try and diffuse the itching, burning and rashes, which beats urinating on them, though its proven that OCS Jellyfish sting relief neutralizes the sting and helps alleviate itching and swelling.

Despite air temps in the 90’s and water temperature of 80+, it’s not just the abundance of jellyfish in Florida’s that was surprising, it was the species. Large numbers of animals washing ashore are the Pelagia Noctiluca or mauve stinger, the cannonball and the Portuguese Man o War although not in abundance yet.  Compact but fitted with long tentacles, these are exactly the same jellyfish that harassed Mediterranean beaches during the summer of 2012 and present this summer.

Scientists believe they were transported across the Atlantic in the Gulf Stream, which wraps around the coast of Florida, suggesting they will be a hindrance on many Gator state beaches this summer. Meanwhile across the pond, biologists who study the Irish Sea are blaming a similar boom in jellyfish there on the overfishing of herring, which has given jellyfish an “exponential boost” in population. The trend has been growing since 2005.

Though explanation for why these jellyfish on these beaches is still being studied, it’s clear that since humankind has taken 100 to 120 million tons of predators out of the sea in the past 20 years it’s left plenty of room for jellyfish populations to boom. Jellyfish thrive in disturbed marine ecosystems, from dead zones to seabeds that have been raked by trawling nets. And they are spreading around the world thanks to powerful currents and aided by stowing away on fleets of ships delivering goods around the globe.

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.”

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.

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 .

Lionfish Distribution as of 2012 as reported by the United States Geologic Survey (USGS) with a great deal of data provided by NOAA and REEF.

Invasive Species: Indo-Pacific LionFish (Pterois volitans) in the Atlantic and Caribbean Sea!

GVI Mexico – August Achievements

The invasion of lionfish, native to the Indo-Pacific, into the Atlantic and Caribbean Sea is not only one of the most rapid in marine history but also having extremely detrimental effects to local species and ecosystems.

Recently introduced via un/intentional release, they have spread extremely quickly throughout the Caribbean, since their first sightings around Florida in 2000, they have spread as far south as Venezuela within 10 years1.

While in their native habitat, lionfish breed seasonally, invasive lionfish in the Atlantic have been documented breeding all-year round2. They can produce between 4000 and 30,000 eggs each time they spawn which are then dispersed great distances along oceanic surface currents, during an estimated pelagic larval duration of 20 to 35 days, before settlement3. Unlike other fish species, Lionfish can settle on and inhabit nearly all marine habitat types and depths between surface levels to over 300m, in temperatures between10-35 degrees Celsius4,5. However, with the rising sea temperatures due to global warming, this potentially invasive region is increasing. Lionfish are also generalist carnivores that can consume over 70 species of fish, up to half their own body length, including commercially, recreationally, and ecologically important species6. On heavily invaded sites, lionfish consume native fish at unsustainable rates. As such, food competition can also lead to depleting food sources for native carnivores.

Here at Pez Maya we have been collecting information on the invasive lionfish so as to document its effects on the local ecosystem. So far this year the average number of sightings per dive per week has been slowly increasing.

As well as a steady increase in the average number of sightings per dive, there is also a noticeable increase in the sizes of lionfish seen on our dive sites. This general increase in size supports theories that invasive lionfish are larger than they are in their native ranges7, suggesting higher levels of local prey consumption and lionfish reproduction this year. In fact, we caught three individuals, one male and two females, that had fully developed and spawning capable gonads or very developed gonads nearing spawning capability.                                                                                                                

Lionfish can inhabit nearly all habitat types, including important nursery areas such as mangroves and lagoon areas, and other areas with high levels of trophic interaction such as the fore-reef and reef crest. As such we have frequently observed lionfish within the reserve at our inner-reef dive sites, such as “Gardens”, which are commonly used as a nursery habitat for juvenile reef fish.

Invasive adult lionfish, however, have been documented as having a preferred microhabitat of complex topographical structures, especially overhanging structures, and lots of coral cover8, such as our dive site “Special K”. As such, the invasive lionfish exhibited similar patterns of microhabitat occupancy as two local, and already over fished, species; the Grouper and Snapper complex, as seen at our local dive site “Hang 10”. The additional stress put on these species through this direct food competition is hindering any efforts to replenish the declining Grouper and Snapper populations.

As discussed before, on heavily invaded reefs lionfish can consume prey faster than their production on, or recruitment to, the reef. As such, the additional stress put on these species through this direct food competition is hindering any efforts to replenish the declining Grouper and Snapper populations. Also, the lionfish is having a negative impact on the Meso-American barrier reef system through the unsustainable consumption of newly recruited herbivorous species by invasive lionfish is limiting algal grazing on a reef system that is already in threat of a shift to an algal dominated reef.

Lionfish feed primarily on teleosts, fish with bony skeletons, which include the majority of the local marine species, and few other crustaceans, primarily shrimps, more commonly consumed by smaller classes of lionfish. However, lionfish are generalist consumers and will quickly abandon their usual diet for any abundant food source.

Because lionfish captured and removed from an area would “be replaced largely through larval recruitment rather than migration of older individuals”9, “localized control efforts would need to be carried out frequently in order to maintain a  younger, smaller population”10, which can be very costly and  makes eradication programs extremely difficult.

However, the data collected here is very useful for future planning of local control efforts and will hopefully be used to co-ordinate our future lionfish control efforts which, if implemented well, can control local populations and even generate income for local communities. Also, and possibly more importantly, lionfish ceviche is a very welcome addition to base cuisine!

How do Jellyfish sting??

The science of cnidocytes and nematocysts

Sea jellies don’t sting through electricity or by touch. A sea jelly sting through a special type of cell called a Cnidocyte, there are three types of cnidocytes currently known. Spirocysts which entangle their prey, Ptychocysts which build tubes for tube anemones and the most well known Nematocysts. Nematocysts consist of a toxic barb which is coiled on a thread inside the cindocyte, when triggered the barb is ejected almost instantly taking only 700 nanoseconds to fire and firing with a force of five million g’s. A cindoctye can only fire once, and must be replaced when fired a process that could take 2 days.

Sea jellies sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes, which are characteristic of all Cnidaria. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom, yet only some species’ venom cause an adverse reaction in humans. When a nematocyst is triggered by contact by predator or prey, pressure builds up rapidly inside it up to 2,000 pounds per square inch (14,000 kPa) until it bursts. A lance inside the nematocyst pierces the victim’s skin, and poison flows through into the victim. Touching or being touched by a jellyfish can be very uncomfortable, sometimes requiring medical assistance; sting effects range from no effect to extreme pain to death. Even beached and dying jellyfish can still sting when touched.

Scyphozoan jellyfish stings range from a twinge to tingling to agony. Most jellyfish stings are not deadly, but stings of some species of the class Cubozoa and the Box jellyfish, such as the famous and especially toxic Irukandji jellyfish, can be deadly. Stings may cause anaphylaxis, which can be fatal. Medical care may include administration of an antivenom.

Detailed Video of firing nematocysts

Jellyfish are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.

Jellyfish are found in every ocean, from the surface to the deep sea. A few jellyfish inhabit freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.
