  1. What a find! The biology of these species is crazy:

    "Despite its appearance, the Portuguese man o' war is not a true jellyfish but a siphonophore, which is not an individual multicellular organism , but a colonial organism made up of many specialized animals of the same species, called zooids or polyps. These polyps are attached to one another and physiologically integrated, to the extent that they cannot survive independently, creating a symbiotic relationship, requiring each polyp to work together and function like an individual animal."

    1. Thanks Ferdy, indeed this is a very interesting Organism! Posted 5 years ago
  2. Occasionally our beaches here on the east coast of Australia will be strewn with hundreds of these, dependent on tide and weather conditions. Albert, this brought a smile to my face as I remembered my Australian husband's words of warning to this British girl when we moved here from the UK..'watch out for the bluebottles and don't touch, the sting is incredibly painful'. A bluebottle is a harmless housefly in the UK. I thought, 'how big and nasty do these flies come, here in Australia?!'. I enjoyed seeing this super, clear image - a beauty with hidden dangers for sure. Posted 5 years ago

The Portuguese man o' war, also known as the man-of-war, is a marine hydrozoan found in the Atlantic, Indian and Pacific Oceans. It is one of two species in the genus "Physalia", along with the Pacific man o' war, "Physalia utriculus". Its long tentacles deliver a painful sting, which is venomous and powerful enough to kill fish and even humans.
