Beautiful Deadly Jellyfish Photography
Portugese man-of-wars are not jellyfish, they’re siphonophores, which mean’s they’re actually a group of organisms, called zooids, that depend on each other to live. The creature gets its name from the upper-most organism which people say looks like the man-of-war warships that were first built by England in the 16th century. A different organism forms the tentacles, which usually hang 30 feet below the surface and have venom-filled nematocysts that are used to kill small fish. Man-of-wars are most commonly found in warm water and sting thousands of humans each year.
