Raised transparent "sail" on a blue oval disk that has concentric circles. Body underneath is dark blue. Short fringing tentacles hang from the disc. Float up to 4 cm across.
These animals float on the surface with their short tentacles hanging below in the water. Their movement is powered by the wind hitting the sail. Each batch of young has some animals with a right-hand sail and some with a left-hand sail, ensuring that they do not all get blown in one direction.
Floating on the surface, may drift near shore due to tides and wind.
Mild sting possible.
