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.

The Australian White spotted jellyfish found in the Gulf of Mexico

The White Spotted Jellyfish or Phyllorhiza punctata, is a native of Australia and is also known as the Australian spotted jellyfish. It grows to the size of about 45-50 centimeters in diameter, and is ocassionally known to grow to a maximum length of just a little over 60 centimeters in size. They look extremely beautiful with the design of white spots over their translucent gelatinous body and their frilly oral arms add another aspect of charm to their appearance. Additionally, they are fairly harmless and their sting contains only mild venom which does not cause any serious effect or reaction in humans.

This jellyfish is an eating machine filtering 13,200 gallons of sea water a day devouring plankton. The white spotted jellyfish has involuntarily migrated to the Gulf of Mexico. It is believed that the animal may have gotten trapped in the ballast tank of a marine vessel and got transported to the Gulf of Mexico where they can now be found in large numbers. The native marine species in the Gulf of Mexico are now beginning to face the problem of non availability of plankton due to the presence of the white spotted jellyfish.

Jellyfish are on the march in the Gulf of Mexico…

That’s the way it seems to many Pensacola area anglers, divers and beachcombers recently, as they report an upsurge in the jellyfish population in local waters.

What seems to be a boom in the slimy invertebrate’s local presence also has been reflected worldwide in reports of jellies being more prevalent and plentiful. The reports have merited study by scientists — including some at the nearby Dauphin Island Sea Lab — who are hoping to learn more about the life cycle of the creatures.

Consider:

• The population of beach-ball-sized jellyfish known as pink meanies, only recently identified as a Gulf of Mexico species, is exploding. They were sighted along Pensacola Beach last year. The pink meanie is known for its cannibalistic ways, and it has a special taste for moon jellies.

• Swarms of moon jellies — numbering in the billions by some accounts — filled the Northern Gulf last year, making it difficult for anglers to reel in their catches, Gulf Islands National Seashore biologist Mark Nicholas said.

• Commercial fisherman Ronnie Hogue said he has seen more Portuguese man-of-war jellyfish — thousands upon thousands — floating in his fishing grounds in the Gulf this spring than he’s ever seen before.

• Area resident Dorinda Bain, 63, said she cannot recall seeing jellyfish of all sorts washing up on Pensacola Beach nearly year-round as they do now.

Similar reports about jellyfish increasing are growing worldwide, according to a Global Jellyfish Group report released recently.

Rob Condon, a marine scientist at Dauphin Island Sea Lab in Alabama, was among the researchers who worked on the report, which scrutinized the unusual reports of jellyfish.

Types of jellyfish you may encounter at the beach and in bays or the Gulf:
» Moon jelly.
» Sea nettle.
» Cannonball.
» Portuguese man-of-war **OCS Portuguese Man o War 1st aid kit available
» By-the-wind sailor.
» Pink meanie.
» Mauve stinger. (Only recently migrated to Northern Gulf.)
» Australian spotted jellyfish. (A species that hitched-hiked into the Gulf in the ballast of ships.)

The group’s research concluded more long-term studies are needed. To get a better handle on what’s going on, the group, in collaboration with University of California Santa Barbara’s National Center for Ecological Analysis and Synthesis, has created a global Jellyfish Database Initiative, called JEDI, to compile data from as far back as the late 1700s and collect new data on jellyfish blooms.

The good news is Ocean Care Solutions Jellyfish Sting Relief has been tested and proven effective on all of these examples plus the Lion’s Mane and the Box..

Eyes hold clues to life for deadly box jellyfish..Queensland

Scientists in far north Queensland say a new discovery about the life cycle of the deadly box jellyfish will allow them to better predict when swimmers are at risk.

Researchers from James Cook University in Cairns have been able to pinpoint the exact time when box jellyfish turn from polyps into deadly stingers.

JCU Associate Professor Jamie Seymour says until now, there have been serious gaps in understanding when people are most at risk from the deadly animals.

“We’ve had a model for about eight or nine years now that predicts the end of the seasons and it does it really, to within two or three days,” he said.

“We’ve been spot on for the last seven or eight years but we’ve never been able to predict the start of the season.”

One of his PhD students, Matt Gordon, is now solving that mystery.

He has been able to get an insight into exactly when box jellyfish hatch by hunting them down off the far north Queensland coast near Weipa and gouging out their set of 24 eyes.

“It’s a lot like the trunk of a tree, it’s got concentric growth rings inside it and each one of those growth rings is added daily so then we were able to age exactly how old those jellyfish were,” he said.

He found the jellyfish turn from tiny polyps into deadly stingers around September but they do not turn up along the coast and start posing a risk to swimmers until November.

“The next thing I’d like to find out is what do they do in that two to three months? Where are they?” he said.

“We know they’re growing quite quickly so from that tiny size, they do reach a decent size quite quickly but where are they? What are they doing? Why is it a couple of months until they show up along the coastline?”

Professor Seymour says his team of researchers is prepared to put themselves on the line to answer those very questions.

“It’s sort of like working with snakes, as long as you get hold of the non-bitey end you’re away and running, ” he said.

“And having said that, it’s fun and if you take the precautions.”

Deadly Jellyfish Weapons Explained..COS Heidelberg University

Heidelberg researchers have succeeded in unravelling the defense mechanisms of jellyfish. Scientists working with Prof. Dr. Thomas Holstein and Dr. Suat Özbek from the Centre for Organismal Studies (COS) of Heidelberg University, together with collaborators from the German Cancer Research Center (DKFZ), analyzed the proteome, or full set of proteins, of the stinging cells in the freshwater polyp Hydra. The results of their research reveal a complex mixture of toxic and structural proteins that can explain the extraordinary toxicity and biophysical properties of these unique cells.

They also show how the energy for discharging the toxin can be stored in the stinging cells and released at extraordinary speed.  With their poison cells, jellyfish and other cnidarians have developed one of the most venomous and differentiated cellular mechanisms in the animal kingdom. Stinging cells, also known as nematocysts or cnidocysts, are found in the outer cell layer of cnidarians and are used for capturing prey or for defense. They consist mainly of a stinging capsule, a giant secretory vesicle. Inside this organelle a long, barbed tubule is coiled up, which turns inside out like the finger of a glove during discharge, thus releasing the deadly poison into the prey.

This mixture of previously unknown toxins paralyses the nervous system of the prey and destroys their cells. Injecting the toxins requires an effective mechanism. Studies have shown that the discharge of toxins is associated with an extremely high pressure of 15 megapascals, whereby the stylet, a thin barb, is able to penetrate even thick crustacean shells. The stylet is accelerated at a force of 5 million g in under 700 nanoseconds, making the discharge of toxins harpoon-like.

Up until now, the molecular components responsible for the biomechanical properties of these unique cellular weapons were largely unknown. The Heidelberg scientists used protein mass spectroscopy to study the cells of the Hydra magnipapillata freshwater polyp. The procedure afforded them a precise qualitative and quantitative analysis of the chemical composition of the substances, thus enabling them to map the nematocyst proteome of the Hydra. Prof. Holstein and Dr. Özbek’s research team were surprised at its complexity. The biologists discovered 410 proteins with venomous and lytic, but also adhesive or fibrous properties. The proteins of the stinging capsule wall contain hitherto unknown structural components that form a tissue-like matrix, a complex protein mesh. This structure of collagen and elastomers surpasses the elasticity and tensile strength of even spider’s silk.

These findings allow the Heidelberg researchers to explain how the energy for discharging the toxin can be stored in the stinging cells and then released from the elastic structure of the capsule wall in nanoseconds at an extraordinary speed.  ”The poison cells of the cnidarians represent an effective combination of the powerful molecular spring mechanism and a structure with extreme biophysical properties,” says Holstein.

The studies also suggest that the organelles containing the injectable toxin have adopted the molecular properties of connective tissue proteins such as collagens during their development. According to Prof. Holstein, it was an unexpected solution in early evolution to develop such a sophisticated mechanism for prey capture and defense.

Portuguese Man o War Facts and information

The main part of the Portuguese Man o’ War is clear and looks like jelly. That is what is often above the surface of the water. They have a sail like design that allow them to easily stay afloat. Below the surface though are the squiggly lines of the body that are a light shade of blue. Those are the tentacles and where they have venom.

They live in the warm waters of the seas around the world. They are often found floating on the top of the oceans. They seem to thrive in the tropical and subtropical areas. Both the Pacific Ocean and the Indian Ocean are full of them. They may end up in the Atlantic Gulf Stream due to wind and current.

The Portuguese Man o’ War has no way of controlling its body in the water. It is completely dependent upon the current of the water. The wind can also influence their movement as can any type of natural disaster.

To help them be well protected they are able to produce venom. When they come into contact with something in the water they are going to release that venom. Each year more than 10,000 people get stung by them due to being in the wrong place at the wrong time. In some areas that have a high number of them there is no longer any swimming allowed.

This has caused some problems in various areas. For example along the beautiful beaches of Australia that people tend to enjoy all year long. Hawaii is a top tourist location but the visitors decrease when there is a high risk of getting stung by them.

Many fish though in the oceans are immune to this venom. They will swim very close to the Portuguese Man o’ War because they know that offers them a great deal of protection from predators. Various predators will keep their distance from this entity because they don’t want to be injected with the venom.

Portuguese Man o' War Facts and InformationPortuguese Man o’ War – Physalia physalis

As they drift around in the water they will take any opportunities that they can to feed. They will consume small fish, plankton and crustaceans. They use their venom to paralyze them so that they are able to prevent their meals from escaping.

Spawning takes place for the Portuguese Man o’ War in the fall. They form large colonies of either males or females. Then the colonies will join with each other so that the eggs of the female colony can be mixed with the sperm of the male colony. Many of them will be consumed by various predators. Those that survive will be able to care for themselves from the moment they emerge.

There is still a great deal that experts don’t know about the reproduction of the Portuguese Man o’ War. Observing them in captivity has been difficult because they don’t due well. They tend not to mate due to the stressful conditions. Due to their dangerous nature it is hard to get close to them to find out what all takes place. However, some studies use underwater cameras that are robot controlled to help them get closer than ever before.

There are three known species of the Man o War…The Atlantic and Pacific Man o War and the Australian species known as the Blue Bottle..The Atlantic Man o War is twice the size of the Blue Bottle and has numerous stinging tentacles whereas the Blue Bottle has one strand.  It’s easy to understand then why the Atlantic and Pacific are known to be lethal and the Blue Bottle has no recorded fatalities related to the sting.

These animals are very nasty stingers and should be avoided at all times…even washed up on the beach…If you have the misfortune of being stung do two things and quickly..have along our Ocean Care Man o War kit for immediate pain relief and first aid but most of all, seek medical attention immediately.

Jellyfish on the rise: UBC study

Jellyfish are increasing in the majority of the world’s coastal ecosystems, according to the first global study of jellyfish abundance by University of British Columbia researchers.

In a study published in this month’s edition of the journal Hydrobiologia, UBC scientists examined data for numerous species of jellyfish for 45 of the world’s 66 Large Marine Ecosystems. They found increasing jellyfish populations in 62 per cent of the regions analyzed, including East Asia, the Black Sea, the Mediterranean, the Northeast U.S. Shelf, Hawaii, and Antarctica.

“There has been anecdotal evidence that jellyfish were on the rise in recent decades, but there hasn’t been a global study that gathered together all the existing data until now,” says Lucas Brotz, a PhD student with the Sea Around Us Project at UBC and lead author of the study.

“Our study confirms these observations scientifically after analysis of available information from 1950 to the present for more than 138 different jellyfish populations around the world.”

Jellyfish directly interfere with many human activities – by stinging swimmers, clogging intakes of power plants, and interfering with fishing. Some species of jellyfish are now a food source in some parts of the world.

“By combining published scientific data with other unpublished data and observations, we could make this study truly global – and offer the best available scientific estimate of a phenomenon that has been widely discussed,” says Daniel Pauly, principal investigator of the Sea Around Us Project and co-author of the study. “We can also see that the places where we see rising numbers of jellyfish are often areas heavily impacted by humans, through pollution, overfishing, and warming waters.”

Map of population trends of native and invasive species of jellyfish by LME. Red: increase (high certainty); orange: increase (low certainty); green stable/variable; blue decrease, grey: no data. Circles represent jellyfish populations with relative sizes reflecting confidence in the data.

Pauly adds that increasing anecdotal reports of jellyfish abundance may have resulted from an expansion of human activities in marine habitats, so the study also provides a concrete baseline for future studies.

The study also notes decreases in jellyfish abundance in seven per cent of coastal regions, while the remainder of the marine ecosystems showed no obvious trend.

Glaucus Atlanticus Sea Slug: Feeds on the Man o War

Glaucus Atlanticus Sea Slug: Animal Of The Week

The Glaucus Atlanticus Sea Slug is as unusual as its appearance suggests – this thing is honestly pretty weird, but we can forgive it since it is so breath-taking.  These creatures are three centimeters long and predominantly colored with silver and blue tints.  They are found in tropical waters, specifically those off of the coast of Africa and Australia.  Though they exist predominantly in these locations, they can also be found off of European coasts.

The Glaucus Atlanticus Sea Slug floats on top of the water by using it’s gas filled sac.  Surprisingly, these tiny slugs actually feed on large, dangerous, poisonous animals; namely the Portuguese Man O’ War.  Yeah, those are the things that you try to avoid at all costs whenever you go snorkeling in the ocean, because their stings hurt like no other.  According to marine biologists, the sea slug can and usually does consume the entire Man o War organism and absorbs the toxins from the creature it just preyed upon, and then saves that poison as a self-defense mechanism.  Pretty amazing given the size of the Sea Slug.

 

Ocean Care Solutions Marine Sting Products; A Growing Necessity for Ocean Swimming Activities

Increased interest brings more people swimming in the oceans up and down the East, West and Gulf Coast regions as tournament events flourish

Open water swimming events have gained significant interest from athletes around the world

Quote start“Ocean Care Solutions is so timely when so many people are swimming in the oceans now.”..John MuenzerQuote end

Tampa (PRWEB) April 16, 2012

One major reason why Ocean Care Solutions marine sting products have become so necessary is because, quite simply, more people are recreating by and swimming in the oceans up and down the East Coast, West Coast and Gulf Coast regions while, at the same time, a substantial number of stinging creatures are swimming or being blown towards shore, creating an impact zone that rings the North American continent. While the majority of beach and ocean goers don’t get stung most of the time, those that do have an unfortunate run in with a marine stinger never forget the experience. And because the sport of open water swimming is exploding like no other, these encounters are growing year by year.

In 1999, there were 220 sanctioned open water swimming races. After with the inclusion of marathon swimming in the 2008 Beijing Olympic Games, the sport took off in unimaginable scope. According to Open Water Source (http://www.openwaterswimming.com), there are now over 6,500 open water swimming events in 158 countries around the world – and the sport continues to grow at a pace greater than one new event per day.

“With the Olympic 10 km marathon swim to be broadcast from in Hyde Park at the 2012 London Olympics, the number of open water events and athletes is poised to multiply like the global jellyfish proliferation our oceans are currently experiencing,” predicated Steven Munatones, director-in-Chief of the Daily News of Open Water Swimming (http://www.dailynewsofopenwaterswimming.com). “With more exposure of the sport and its heroes, more events get started. With more events available, more individuals challenge themselves to venture beyond the shorelines. When more individuals participate in open water competitions, there is an increase in traditional and new media exposure of the sport. The cycle feeds upon itself, enabling the sport to grow at unprecedented levels.”

The sport offers amateur swims, professional races, solo challenges, charity events, relays and extreme swims of all sorts in oceans, lakes, seas, rivers, bays, estuaries, channels, canals and fjords. Everywhere marine life exists, humans are seemingly challenging themselves. “You have newcomers to the sport and then you have guys like John Muenzer,” explains Munatones. “John was a former college swimmer who took on the traditional responsibilities of work and family after his student-athlete days were over. But then he got the bug and started swimming again. Not only did he join a masters swim club, but he also somehow balanced work and a family of seven while swimming the English Channel, setting a solo marathon record in Lake Erie, and is now thinking about swimming to the Farallon Islands, west of the Golden Gate Bridge.”

“And that is the beauty of the sport. The world is so unexplored when it comes to humans swimming in open bodies of water. People can challenge themselves, plan their own adventure and set all kinds of records by swimming unprecedented distances in lakes, river, channels and oceans around the world – or even in their local area. This excitement – to do a swim that has never been done before in the history of mankind even in your own state – is pretty thrilling for the average swimmer in the 21st century. We want to recognize their achievements and encourage them to train and complete their swim safely.”

Which is where Ocean Care Solutions comes into play. While sharks and cold water are usually the first obstacles that come to mind when swimming in the ocean, it is the unseen and much smaller jellyfish and Portuguese Man o War that often present disguised barriers to success.

“I agree 100%,” says John Muenzer. “Sure, you always think about sharks and Jaws comes to mind. But it is the little jellyfish that really hurt. You get zapped by those and you just can’t stop thinking about the sting. The pain can be unbearable. They just come up on you when you least expect it. Their venom is a show-stopper which is why products like Ocean Care Solutions is so timely when so many people are swimming in the oceans now.”

“Our jellyfish sting solution and marine sting first aid kits, like the Man o War kit, are specifically designed, using the latest medical and scientific research, to provide on the spot, first aid pain relief,” explains Kevin Freeman, CEO of Ocean Care Solutions. “We are very excited about our products and our partnership with the Open Water Swimming Community in providing effective first aid to world class athletes.” “We began with the simple idea of providing effective marine sting first aid products for the family trip to the beach so we are very pleased to know our products have raised so much interest with international swimmers,” Freeman continued.

Ocean Care Solution products are safe to use and come complete with step by step instructions and all the medically supported components necessary to provide immediate first aid for a variety of marine sting injuries. Light weight, durable, OCS signature gold foil pouch can go any where there is an ocean activity.
