Description: This species has four pairs of oral arms that appear ribbon-like under the subumbrella without any marginal tentacles and terminal clubs. The number of lappets varies with deep clefts between lappets. Some specimens showed colour variations of the umbrella, mostly white or light pink with purple margins and only a few specimens with intense blue umbrellas, but all specimens exhibited dark brown spots on the umbrella surface and margin. The species has a mild sting. The average exumbrella diameter ranges from 100-120 cm.
