The Australian Salmon (Arripis trutta) is a streamlined fish with a slender, elongated body. Known for its distinctive bluish-green dorsal colouring and silvery white underside, it thrives in the waters around Australia and New Zealand. Juveniles inhabit sheltered estuaries, while adults migrate long distances, forming large schools in oceanic and coastal waters. A carnivorous species, it primarily feeds on small fish and crustaceans. Its ecological significance includes supporting marine predators and seabirds by driving baitfish to the surface, thus connecting various marine food web levels.
