 It is thought to be a signal of reproductive arousal or aggression, similar to the "zebra display" behaviour of "Sepioteuthis sepioidea", the "intense zebra display" behaviour of "Sepia officinalis", and the "lateral display" of "Loligo plei".Females will also sometimes use this display to rebuff courting males.There are three known courtship behaviours in bigfin reef squids, dubbed "male-upturned" mating, "male-parallel" mating, and "head-to-head" mating.
