Bluefish

Bluefish is the “predator” in fact it feeds exclusively on other fish and cephalopods. Its favorite preys are mullets even if in this video we see it hunting in a few meters of depth, trying to capture salemas present in numerous specimens in a herd.

As always, the encounter is lightning-fast and lasts only a few seconds, in fact the Serras do not let themselves be distracted when they are hunting and it is extremely difficult to get close. By slowing down and enlarging the video we managed to extrapolate some images of this splendid fish.

Bluefish (Pomatomus saltatrix Linnaeus, 1766) is a sea fish. It is the only one belonging to the Pomatomidae family.

Distribution and habitat
It is a cosmopolitan species in tropical and subtropical waters. It is common in the seas of Italy and in the rest of the Mediterranean Sea and in the Black Sea; in the eastern Atlantic Ocean it is found as far north as Portugal. Its abundance varies from year to year, in some periods it is very common and then disappears for entire years. It is migratory, moving to warmer waters in winter.

It is a typical pelagic fish, in summer it approaches the coasts and, being euryhaline, it penetrates the mouths of the rivers to hunt the mullets of which it is greedy.
