The way a Portuguese Man O’War feeds themselveselves is very interesting.
Usually, the tentacles dangle underneath them and wait for a school of fish to swim past. The stronger tentacles pull the fish in and passes it to special tentacles that digest it, liquefying it with powerful chemicals (Mainly Argon). The chemicals take immediate effect. Eventually, all that will be left is a scaly husk. Even if the tentacles are detached or the Portuguese Man O’War is dead, the chemicals are still very powerful.

Sometimes, the sting can kill humans. The sting itself actually isn’t the one who kills the human. It is the pain that disables humans to get to shore. The victim stung by the tentacle will most likely drown instead.

There are certain animals who are immune to the Portuguese Man O’War. For example the blanket octopus. What’s interesting about that is that the octopus not only eats the jellyfish, it also reuses its tentacles to hunt other animals.

The Portuguese Man o'war actually doesn't swim. It sails across the sea in colonies.

The Portuguese Man O’War is made up of four polyps, or sails. The top one is a brightly coloured purple, blue, or pink gas-filled float. When the top polyp is filled with gas, it looks like the eighteenth century Portuguese war ship. The top polyp is like an “umbrella” for the other three polyps. The next polyp is used to catch prey such as smaller fish and plankton. The final two polyps are used for gender identity and digestion. What’s crazy is, the Portuguese Man O’War has no gender. It is neither male nor female.

The Portuguese Man o'war atually doesn't have a home. Instead, it floats along the ocean's currents so it lives whereever the ocean brings it.
