The tentacles can be very long and similar to a thin piece of hair that sticks to our human skin like velcro!
The man o’ war will eat basically anything that comes into contact with their stinging tentacles. , a jellyfish scientist and lecturer with the National University of Ireland (NUI) Galway.

The results, published this week in the journal Toxins, defy the recent abandonment of historic advice, and suggest that man o’ war stings are no different than other jellyfish stings; the best first aid is to rinse with vinegar to remove any residual stingers or bits of tentacle left on the skin and then immerse in 45°C (113°F) hot water or apply a hot pack for 45 minutes.
Once finally getting onto the shore, I rinsed my board and myself (wound included) with fresh water, from the beach showers, to rinse off any remaining tentacles (try to rinse it all off in the ocean without using fresh water).
Im weiteren Sinne werden manchmal eng verwandte Arten aus derselben Gattung wie Physalia utriculus als Portugiesische Galeere bezeichnet. Man-of-war tentacles have coiled stingers that have a very powerful and painful venom. As Dvorsky reports, the researchers found many potential treatments—including dousing the sting with urine, alcohol, soda, lemon juice and dish soap—all caused the cnidae… The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. The tentacles can grow to 165 feet long.
These polyps are of three specialized types, each having a specific function.
Trusted first aid sources have recommended that Portuguese man o’ war jellyfish stings be treated differently from others. 2.
Like cast members on a distasteful reality show, Portuguese man-of-war "jellyfish" are descending upon the Jersey Shore in increasing numbers.
Let others around you know that they are around because if you see them on the beach, it’s more than probable you will find more than a handful in nearby waters. But scientists at the University of Hawai‘i at Mānoa (UHM) have researched current literature and found little evidence to support unique treatment for these stings. The effects of this venom can range from mild to life threatening, but typically include immediate pain that can last upwards of 15 to 20 minutes. The Portuguese man o' war (Physalia physalis), also known as the man-of-war, is a marine hydrozoan found in the Atlantic, Indian and Pacific Oceans. It is translucent and tinted either shades of pink, blue, or purple.
The body grows between 3 to 12 inches long and may extend above the water by as much as 6 inches. As the man o’ war drifts across the surface of the ocean carried by the wind its tentacles are constantly search through the water underneath it for food.Muscles in each tentacle contract and drag prey into range of the digestive polyps, the gastrozooids, which, acting like small mouths, consume and digest the food by phagocytosis – by secreting a full range of enzymes that variously break down proteins, carbohydrates and fats. Doyle and his team researched the Atlantic man o’ war and found that first aid using vinegar and hot water immersion or a hot pack are the best method of treatment. The prey consists mostly of small crustaceans, small fish, algae and other members of the surface plankton which the man-of-war ensnares in its entangling, stinging nematocystic threads.The sting of the man o’ war is extremely painful to humans and can cause very serious effects including fever, shock, and interference with pulmonary and respiratory functions.
The poisonous landmines sting hundreds of people each day around the world. In contrast, research by Yanagihara and Wilcox found that common first aid tactics of rinsing with seawater and applying ice packs actually made stings much worse. Stings from a Portuguese man o’ war are as common as they are dangerous, yet there’s a lack of consensus over the best way to treat these painful pricks. New research from the University of Hawaii at Manoa (UHM) and the National University of Ireland (NUI) Galway now shows that most of these ideas are complete bunk—if not counterproductive—and that the best approach is to apply a bit of vinegar and some warmth. Thousands of Portuguese men-of-war washing ashore in Oahu have delivered painful stings to hundreds of beachgoers, Hawaii News Now reports.

Treatment methods for man o’ war stings from the Atlantic species of Physalia are the same. Check out this useful Box jellyfish calendar, Unlike man-o-war, the box jelly navigates purposefully toward a light source where the man-o-war is guided by the ocean waves, currents, winds, and tides.
