BLUE FISH
The bluefish is a moderately proportioned fish, with a broad, forked tail. The spiny first dorsal fin is normally folded back in a groove, as are its pectoral fins. Coloration is a grayish blue-green dorsally, fading to white on the lower sides and belly. Its single row of teeth in each jaw is uniform in size, knife-edged, and sharp. Bluefish commonly range in size from seven-inch (18-cm) "snappers" to much larger, sometimes weighing as much as 40 lb (18 kg), though fish heavier than 20 lb (9 kg) are exceptional.
Adult bluefish are strong and aggressive, and live in loose groups. They are fast swimmers which prey on schools of forage fish, and continue attacking them in feeding frenzieseven after they appear to have eaten their fill.[9][10] Depending on area and season, they favor menhaden and other sardine-like fish (Clupeidae), jacks (Scombridae), weakfish(Sciaenidae), grunts (Haemulidae), striped anchovies (Engraulidae), shrimp, and squid. They are cannibalistic and can destroy their own young.[18] Bluefish sometimes chase bait through the surf zone, attacking schools in very shallow water, churning the water like a washing machine. This behavior is sometimes referred to as a "bluefish blitz".
In turn, bluefish are preyed upon by larger predators at all stages of their lifecycle. As juveniles, they fall victim to a wide variety of oceanic predators, including striped bass, larger bluefish, fluke (summer flounder), weakfish, tuna, sharks, rays, and dolphins. As adults, bluefish are taken by tuna, sharks, billfish, seals, sea lions, dolphins, porpoises, and many other species.
Bluefish should be handled with caution due to their ability to snap at unwary hands. Fishermen have been severely bitten, and wearing gloves can help. Wading or swimming among feeding bluefish schools can be dangerous.[19] In July 2006, a seven-year-old girl was attacked on a beach, near the Spanish town of Alicante, allegedly by a bluefish.[20]
