In these observations other fish species than those sampled from specimens were observed as prey e. In summer they form schools of up to fish, although most schools number fish, in areas where there are strong currents. These schools are predominantly made up of sub-adult fish with the smaller fish nearer to the surface and the larger, usually female, fish at the bottom of the school at depths of up to 30m. In winter the only aggregations are small groups of juveniles in shallow bays.

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.

In the Azores juveniles of Sphyraena viridensis are preyed upon by the lizard fish Synodus saurus , this predation shows that there is an overlap in habitat between the juvenile barracudas and the lizard fish which occur in sheltered, very enclosed bays with sandy substrates. Sphyraena viridensis is landed in small quantities in the eastern Mediterranean by fishermen using in trammel-nets and beach-seines.
