And like a sailing ship, it relies on the wind and tidal movements to get about.So named because it looks like a Portuguese battleship with sails.Some Portuguese Man-of-War, or bluebottle, facts: Certainly a lot less frightening than the fearsome sounding Portuguese Man-of-War. Sounds quite cute really, like a character out of The Goon Show. That’s what they’re called here in Australia. Or sometimes, when I am walking along the golden sands, I will come across little blue lumps of dead jelly attached to a thin blue line of string. Every now and then, when I’m visiting a beach somewhere here in sunny Australia, I see a sign like this…. Now let’s fast forward hundreds and hundreds of years to today. Nobody was really sure whether these things had reached the beaches of my home town, but just knowing there was a possibility was enough.īut what did seem common knowledge was that one single sting from this beast would lead to instantaneous death! Even to a small child, this seemed pretty final and to be avoided at all costs.īut these days, we know that to have a real good chance of instant death after a jellyfish sting, swim among the Irukandji. Yes, stories of jellyfish lurking in the darkened seas of Southend were common, so I would be constantly surveying the surface area around me looking for tentacled shadows approaching.īut the biggest, biggest, biggest fear was reserved for the Portuguese Man-of-War. In those days, probably my biggest childhood fear was getting stung by the dreaded jellyfish. Those of you who have read my about me page will know that when I was a kid, I first practiced my surfer dude moves on the beaches of Southend-on-Sea. To avoid threats on the surface, they can deflate their air bags and briefly submerge.Life in Australia – Moving to Australia – By BobinOz ≡ Menu They have no independent means of propulsion and either drift on the currents or catch the wind with their pneumatophores. Man-of-wars are found, sometimes in groups of 1,000 or more, floating in warm waters throughout the world's oceans. A fourth polyp contains the reproductive organisms. Muscles in the tentacles draw prey up to a polyp containing the gastrozooids or digestive organisms. But beware-even dead man-of-wars washed up on shore can deliver a sting. For humans, a man-of-war sting is excruciatingly painful, but rarely deadly. They are covered in venom-filled nematocysts used to paralyze and kill fish and other small creatures. These long, thin tendrils can extend 165 feet in length below the surface, although 30 feet is more the average. The tentacles are the man-of-war's second organism. Man-of-wars are also known as bluebottles for the purple-blue color of their pneumatophores.

The Portuguese man-of-war is a siphonophore, an animal made up of a colony of organisms working together.
