It typically has eight thin, stringy, long, dark tentacles and four white frilly shorter tentacles for feeding.
The sting can be very painful. The young medusa has a pinker bell without dark stripes.
They can reach 70cm across. Diet is zooplankton. They are prey to leatherback turtles.
Like other jellyfish, they have a multiform life cycle of egg, planktonic larva, polyp, ephyra and medusa.
