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

Golden Stingray commonly found in the Eastern Atlantic, Mediterranean and Black Sea…

The most common sting ray found in the Eastern Atlantic (North Sea, Baltic to Mauritania) as well as the Mediterranean and Black Sea is the Pastinaca or Golden Stingray. This ray has a rhomboid shaped disc with straight anterior margin and mildly convex posterior margin with a pointed snout and a small protrusion. Generally skittish about human intrusion but has proven tolerant while feeding. This ray is dangerous to swimmers and salt water sports fishermen to poisonous barbed spine.  Don’t forget the shuffle but if you do…

A record-breaking school of Devil Rays has arrived off the coast of Baja

The devil ray (M. mobular) belongs to a small sub-family of stingrays that includes the gigantic zooplantophagous manta ray (Manta
birostris) which can measure 8m in width and weigh 3 tons. In the Eastern Atlantic the devil ray is found southwards from northern Spain and Portugal, throughout the Mediterranean (but not the Black Sea), and onwards
via the Canaries and Azores to Senegal and has been known to possibly stray into the North-Western Atlantic from New Jersey to Cuba.  check out this Utube provided by NatgeoTV.

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.

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.

The Flower Hat Jellyfish..Brazil, Argentina and Japan

This jellyfish is a rare species and is generally small in size with a width of just about six inches. It is also known as Olindias Formosa and is very striking with shades of purple and orange colours. It has appearance of having a neon pink flower hat on its head. This is because its tentacles, when not in use, coil up and sticks to the rim. It has a painful sting but non-lethal to humans. It mainly feeds on small fish capturing its prey by injecting venom from its stinging cells its tentacles. It inhabits Brazil, Argentina and Japanese waters.flower hat jelly 10 of the Most Beautiful Jellyfish in the World
