No territorial behaviour was observed. Schooling is thought to be an anti predator defence and to facilitate mating with the smaller males being attracted to the larger females, in addition groups of barracudas were more successful in hunting prey fish than single fish. This species does not appear to mix with other barracuda species in mixed schools but there are reports of these fish associating with whale sharks in the Azores and an instance of them actively swimming towards a manta ray Mobula tarapacana.[1]
