Often mistaken for jellyfish because of their jelly-like appearance, the man-of-war is a species of siphonophore whose distinctive blue gas-filled bubble that floats above the water looks like ...
Often, finding a single Portuguese man o' war is followed by finding many others in the vicinity. [37] The Portuguese man o' war is well known to beachgoers for the painful stings delivered by its tentacles. [36] Because they can sting while beached, the discovery of a man o' war washed up on a beach may lead to the closure of the beach. [60] [61]
Carl Linnaeus described the first siphonophore, the Portuguese man o' war, in 1758. [11] The discovery rate of siphonophore species was slow in the 18th century, as only four additional species were found. [11] During the 19th century, 56 new species were observed due to research voyages conducted by European powers. [11]
Jellyfish stings can trigger a complex immune response in human skin similar to the response to pathogens or allergens. When jellyfish venom , carried by the stinging cells of the animal ( nematocysts ), comes into contact with the skin, it interacts with various cells and substances in the body.
Here are a few things to know about jellyfish and their close cousins, the man o’ war, which globally sting about 150 million people a year. 1. Let’s get it out of the way. Don’t pee on that ...
