In the same study the predatory behaviour of S.viridensis was observed and they are active pursuit predators of fish with one or many barracudas pursuing fish, either singling out lone prey or attacking shoals of prey fish. The pursuit was rapid and was usually over in 8–40 seconds and the more fish were involved the higher the rate of success was. In these observations other fish species than those sampled from specimens were observed as prey e.g. longspine snipefish Macrorhamphosus scolopax and boar fish Capros aper.[1] It is also known to feed on cephalopods and crustaceans.[2]
