Did not expect to have Alabama Gulf of Mexico Coast jellyfish* stings PTSD from 8 minutes into a horror movie (The Devil's Mouth. Set in Thailand). Guess that affected me more than I thought. Might explain why I'm not a beach person besides the sand getting everywhere.

"Y llegará el día en el que los huevos fritos cobrarán vida" - Evangelio de San Arguiñano 2:45
Es la medusa Cotylorhiza tuberculata del Mediterráneo, que con la Phacellophora camtschatica tienen el privilegio de ser los huevos fritos del mar. #medusas #jellyfish

La medusa corona (Periphylla periphylla) nace en la oscuridad y es moldeado por ella. La luz puede dañarla, especialmente a las jóvenes, por lo que vive en aguas turbias o en profundidades de hasta 2700 m.📷 Jackson W.F. Chu #medusas #jellyfish

La medusa autoestopista (Vallentinia gabriellae) se deja ver cuando le apetece. Esta medusa de 12 mm es difícil de encontrar en el mar, pero puede aparecer por sorpresa en los cultivos marinos en el laboratorio a través de algas Ulva, Sargassum y Enteromorpha y conchas de moluscos. 📷Allen G.

Pelagia noctiluca una acompañante habitual en nuestras inmersiones en la costa tropical; es una de las medusas más bellas y peligrosas del mediterráneo
👉 Es bioluminiscente gracias a una proteína para ahuyentar depredadores o atraer presas
👉 Sus tentáculos pueden medir más de 3 metros y su picadura es dolorosa, las sensación es como un calambrazo
👉 Un consejo: admirar siempre desde la distancia, posicionarnos al lado contrario de dónde va la corriente y nunca detrás o debajo de los tentáculos

#Jellyfish are taking over the world – and #ClimateChange could be to blame
Jan 8, 2019
by Sean Fleming
Senior Writer, Forum Stories"For 500 million years, jellyfish have been part of the maritime #ecosystem, but now they’re poised to take over the earth.
"They have no brain, no eyes, no spine, not even blood, but they have a remarkable capacity to reproduce and can pack an impressive sting, both literally and figuratively.
"Most recently, vast numbers of bluebottle jellyfish were pushed ashore by unusually strong winds and spells of hot weather in #QueenslandAustralia, stinging thousands of people and forcing the closure of popular swimming spots. About 13,000 stings were recorded in the past week.
"In June last year, over the course of just one week, over 1,000 people were stung in Volusia County, #Florida, following a period of exceptionally prolific jellyfish blooms. The explosion in their numbers has been attributed to warming seas and even increased pollution; unlike many other marine creatures, jellyfish can cope with reduced oxygen levels.
Small but deadly – at least some of the time
"Typically, jellyfish range in size from 1cm to 40cm. But they can be significantly larger – the #LionsManeJellyfish, for example, can reach 1.8 metres wide, with tentacles over 15 metres long.
"For the most part, the sting of a jellyfish is more unpleasant than it is harmful. The pain comes from venom delivered via millions of microscopic barbs in the creatures’ tentacles. Most jellyfish stings will only have a localized effect on the victim – redness, swelling, and discomfort where the barbs make contact with the skin.
"Some, however, will prompt a systemic, whole body, reaction. These may take several hours to emerge and can include symptoms such as headaches, nausea and drowsiness.
"In rare cases, the sting can be fatal. This is true of the #BoxJellyfish, which is spreading into waters that had previously been too cool to support it; its venom causes a severe reaction that can cause death within minutes.
A force of destruction
"But these booming jellyfish populations are doing far more harm than ruining people’s trips to the beach. In fact, the scope of their disruption has extended far beyond the water’s edge.
"In 2011, both reactors at the #TornessNuclearPowerPlant in #Scotland were shut down after an invasion of jellyfish started blocking the cooling filters. Two years later, the jellyfish struck again – this time in #Sweden. They forced the closure of the #OskarshamnNuclearPowerPlant, which contains the world’s largest boiling-water reactor.
"The island of Luzon, home of the Phillippines’ capital Manilla, suffered a blackout in 1999 due to jellyfish, and in 2006 the #USSRonaldReagan, a nuclear-powered aircraft carrier, was brought to a standstill by thousands of the little creatures. And while these events may stand out as exceptions, they are increasing in both scale and frequency.
"From sea-bed diamond mining in Namibia to salmon farming in Ireland, even jeopardising the sustainability of beluga caviar farming in the Caspian Sea, jellyfish are as destructive as they are abundant. And that abundance is being caused by a variety of factors, many of which are related to human activity.
Some like it hot
"Over the last hundred or so years, the average surface temperature of the world’s seas has risen by about 0.9°C. As the oceans get warmer, marine animals are able to spread into areas that had historically been too cold. Oxygen levels in the sea have fallen by around 2% over the last 50 years, due to rising temperatures and #pollution [including #NuclearOceanDumping, which reduces oxygen levels]
"Jellyfish can thrive in areas with lower oxygen levels, where other animals suffer. But there are other factors at work, too. Fishing has depleted the global stocks of some of the jellyfish’s natural predators – such as #tuna and #swordfish – and some they compete with for food – such as anchovies. With more food and fewer predators, some jellyfish populations can grow unchecked.
"In the #BlackSea, unchecked population growth is precisely what’s happened. #AnchovyFishing in the region had caused harm to the Black Sea’s ecosystem by the time stowaway jellyfish made the journey there from the eastern seaboard of the USA. Most likely transported in the ballast water of ships that made the crossing, 1982 saw the arrival of the warty comb jelly. By 1990, there were 900 million tons of them in the Black Sea.
"There are believed to be around 200 different species of jellyfish, not all of which can sting, and some are considered edible. This could offer one potential, and creative, approach toward dealing with an over-abundance of jellyfish – co-opting them onto our dinner plates." [That's one way to deal with invasive species -- eat them into extinction!]

Three native bees gorging on the pollen of a pig face flower (Carpobrotus Edulis) - spotted yesterday on Teewah beach! Not only are the fruits of this plant edible (albeit pretty salty!) The juice from its succulent leaves has a couple of interesting medicinal properties: it can help treat sunburn, minor cuts, insect bites, stings, and even jellyfish burns! Given its preferred habitat of sand dunes and beach areas, this knowledge might come in handy one day. It also has antibacterial properties and can be used to treat minor mouth infections or a sore throat when mixed with water and used as a gargle. Are you growing pigface in your garden yet?
