It’s also been suggested that Renaissance-era sailors thought the pneumatophores resembled the helmets worn by Portugal’s soldiers during the 16th century. As for the Portuguese part, 19th-century scientists proposed that sailors encountered it near the Portuguese island of Madeira, while modern etymologists tend to think that it looked like the Portuguese version of the ship. Physalia physalias colonies spend a lot of time floating at the water’s surface, and when the gas bladder is expanded, it looks and acts a bit like a sailboat, hence the man o’ war moniker. British sailors took to calling this kind of vessel a “man of war.” In the Age of Sail, many European navies used tall warships loaded with cannons and propelled by the wind. ![]() The name Portuguese man o’ war probably refers to a naval ship. It’s smaller than the Atlantic species and, unlike its bigger counterpart, it hunts with a single, elongated tentacle. It’s sometimes called the Indo-Pacific Portuguese man o’ war and is restricted to the Pacific and Indian oceans. When we say Portuguese man o’ war, we’re talking about Physalia physalis, the siphonophore also known as the Atlantic Portuguese man o’ war, which can be found in warmer parts of Pacific, Caribbean, Indian, and Atlantic waters.Īnother kind of siphonophore that regularly stings beachgoers is the bluebottle, Physalia utriculus. Indo-Pacific bluebottles are close relatives. An expanded float also enables the colony to harness winds to move around. Capable of expanding or contracting at will, it provides the man o’ war with some buoyancy control. Every man o’ war also has a pneumatophore, or “float”-an overgrown, bag-like polyp which acts as a giant gas bladder and sits at the top of the colony. Dactylozooids are long hunting tentacles built to ensnare prey gastrozooids are smaller tentacles which digest the food and gonozooids are dangling entities whose job is to facilitate reproduction. Though the zooids within a man o’ war are basically clones, they come in different shapes and serve different purposes. They must cooperate as one in order to do things like travel and catch food. These tiny organisms, called polyps or zooids, can’t survive on their own, so they merge together into a tentacled mass. But as it develops, it starts “budding” into distinct structures and organisms. A siphonophore starts out as a fertilized egg. The Portuguese man o’ war may look like a bloated jellyfish, but it’s actually a siphonophore-a bizarre group of animals that consist of colonies made up of dozens, hundreds, or even thousands of genetically identical individual creatures. The Portuguese man o’ war is not a jellyfish. Read on to learn more about these unusual creatures. beaches-which leads to problems for beachgoers. ![]() If you are unlucky enough to be stung by one of the animals, the Shore Beach Service has some recommendations: "Advice on a remedy is varied, but most agreed to soak in hot water and seek further medical attention.The dangerous Portuguese man o’ war, which has a potentially deadly sting, is often sighted on U.S. The Shore Beach Service patrollers are currently gathering as many of the creatures as they can and burying them under the sand to prevent anyone stepping on them. "It also is less common to see them in large numbers in the winter, but certainly not unheard of." "Usually we'll see these or other jellyfish show up in numbers when there have been strong storms offshore, but I don't know of any recent offshore storms," Daniel Season, a research scientist with the Marine Resources Institute, told FOX Weather. They are mostly found in tropical and subtropical waters. Stock image of a Portuguese Man O' War floating in the ocean. ![]()
