In Australia, the term ‘bluebottle’ is used to refer to the marine organism known to Europeans as the Portuguese man of war or by its scientific name of Physalia utriculus.
Bluebottles can inflict unpleasant stings if their tentacles come into contact with human skin, but are not considered a serious danger. In summer, bluebottles washed up in or around the ocean pools can make swimming unpleasant and limit sunbathing areas. They also provide amusement for children who enjoy popping the floats of bluebottles. The Bondi women’s water polo team was named after the bluebottles.
