The video initially shows the long tentacles of the jellyfish, which reach more than two metres. Shocked users left many comments, vowing never to swim in the ocean.
The numerous tentacles of the Portuguese Man o' War are equipped with a huge number of stinging cells, which pack a poisonous punch for unsuspecting prey. The tentacles are almost colourless; they merge with sea water and are difficult to see.
The Portuguese Man o' War lives in the tropics and subtropics, in the Indian and Pacific oceans. Usually, they are seen near the Australian coast during the summer.
