Transparent, clear to blue balloon float with a single prominent, blue tentacle underneath. Float about 6 cm across, tentacles up to 1 m long.
These animals float on the surface with their tentacles hanging below in the water. The float can be orientated in one of two ways so that individuals are blown to the left (left-sailing) or to the right (right-sailing). This ensures that they do not all get blown in the same direction.
Floating on the surface, may drift near shore due to tides and wind.
Painful sting that requires medical advice. Specimens washed ashore are still able to sting.
