Fatal stings are extremely rare, and usually result from allergic reaction to multiple stings. The species does not have any tentacles; however, they still have stinging cells, called nematocysts , within their bells, which can produce mild stings to humans. Consult a doctor or other health care professional for diagnosis and treatment of medical conditions. Jellyfish are common sea creatures and many of them sting. Once beached and apparently inert, the man o' war still stings, since the cysts on the 'tentacles' will be alive for some time.Deaths from the man o' war are possible but vanishingly rare - two have been reported in the last fifty years, neither in UK waters. In both cases the victim appears to have had an allergic reaction (Avoid touching jellyfish. https://www.leisurepro.com/blog/explore-the-blue/5-harmless-species-jellyfish News Corp is a network of leading companies in the worlds of diversified media, news, education, and information services.A HUGE explosion that rocked Lebanon's capital Beirut in August 2020 created a mammoth mushroom cloud that dwarfed the city.We explain what causes a mushroom cloud, and why it's not proof of a nuclear detonation.A mushroom cloud is the result of a large explosion.We usually associate mushroom clouds with a nuclear detonation, but they can be caused by many types of explosion or impact.The cloud itself is typically made up of debris, smoke and condensed water vapour.For a mushroom cloud to form, an explosion needs to create a very hot bubble of gas.Importantly, this bubble of gas needs to have a lower density than the air around it.That means it moves faster and fills more space than surrounding air.The gas moves up quickly, dragging up nearby air that is trying to sink – with a central column that rises rapidly.Eventually, the gas rises high enough that it's no longer less dense than the surrounding air.So this gas, debris and vapour spills out at all angles, creating the "head" of the mushroom cloud.Any significant high-energy explosion can create a mushroom cloud – including thermobaric weapons – which is why we associate them with nuclear detonations.Mushroom clouds can also be created naturally, through volcanic eruptions – or impact events, like a meteor strike.The event was notable for creating a large mushroom cloud that dominated the city's skyline.But officials have dismissed suggestions that the explosion was caused by a nuclear detonation.The president of Lebanon said that around 2,750 tons of These chemicals are said to have been stored in a port-side warehouse for six years.Ammonium nitrate is a chemical compound best known for its use as a high-nitrogen fertiliser.But it is also used in explosives, particularly for mining, quarrying and construction.It is a major component in ANFO, which accounts for 80% of industrial explosives used in the USA.Significant amounts of ammonium nitrate exploding can create a mushroom cloud. Use a stick. It is generally better not to touch a jellyfish at all, even if you think it is a harmless variety and even if it is beached and appears dead, as it may still sting.If you see jellyfish in the water, swim away and be aware that jellyfish are generally found in groups.A wetsuit will protect you against most jellyfish stings, although exposed parts of your skin like hands, face and feet will still be stingable.Symptoms include a localised stinging pain, itching, rash, and raised stripes (welts). Stings cause pain lasting 2-3 hours. They are rare in the UK, but common in the Mediterranean in summer. Hot packs then speed the breakdown of the man-o'-war toxins already in the skin.Topical vinegar is not universally accepted as treatment for Portuguese man-o'-war stings in Australia, as it can worsen stings from a similar multi-tentacled The most dangerous and indeed deadly species of jellyfish, where humans are concerned, are some of the box jellies found in the Indo-Pacific ocean and around the coasts of Australia, particularly to the North, and the Philippines.Box jellyfish are pale blue and transparent with a cube-like bell. Registered in England and Wales. Signs warn swimmers not to rub a sting, but instead to douse it in vinegar. In general the sting is not even powerful enough to get through human skin, so any claims of this jelly being one of the world’s most dangerous, or even deadly are way overblown. The frilled bell is reddish-brown and can be up to two metres in diameter. Symptoms of sea creature stings The main symptoms of sea creature stings are intense pain where you're stung and an itchy rash. A mushroom cloud is the result of a large explosion. This is the best way to remove remaining cysts trapped in or clinging to the skin's hairs. If they happen to be alkaline you will cause more toxin to be released and make the sting and the pain worse.It is useful to know what to do if you get stung by a jellyfish in the UK, although if you swim in tropical seas, particularly the Indo-Pacific, it is vital to have this information and to be prepared. They are believed to be the oldest multi-organ animal species, dating back over 500 million years.Coronavirus: how quickly do COVID-19 symptoms develop and how long do they last?Coronavirus: what are asymptomatic and mild COVID-19?COVID-19: how to tell hay fever and coronavirus apartCoronavirus: what are moderate, severe and critical COVID-19?Not all jellyfish sting.
