Crevalle Jack

Crevalle Jack

A wide-ranging Atlantic species found from the Canadian maritimes to Uruguay and across the eastern Atlantic from Portugal to Angola, the crevalle jack is built for speed and endurance in a way few inshore fish can match.

Schools herd baitfish to the surface in churning, visible blitzes that anglers can spot from a distance — and even a modest fish in the 3–5 lb range will test tackle and stamina with sustained, powerful runs. Larger fish push past 50 lbs and often run alone.

Scientific Name: Caranx hippos

Also known as Common jack, Black-tailed trevally, Toro, Jackfish, Yellow cavalli

Physical Characteristics:
  • Bluish-green to greenish-gold on the back, fading to a silver or yellowish belly — the color contrast is one of the quickest field marks.
  • Two black spots are the key ID feature: one on the gill cover, one at the base of each pectoral fin. No other common jack shares this exact combination.
  • Deep, compressed body with a steep, blunt forehead — the head profile alone distinguishes it from more streamlined jacks like the amberjack.
  • Hard bony scutes (modified scales) line the caudal peduncle; the second dorsal and anal fins are nearly mirror images of each other in size.

What to know

Habitat Distribution

  • Native to the western Atlantic from the Canadian maritimes south to Uruguay, including the Gulf of Mexico and Caribbean; also present in the eastern Atlantic from Portugal to Angola and into the Mediterranean.
  • A salinity generalist — equally at home in full-strength saltwater, brackish estuaries, and occasionally tidal freshwater reaches of coastal rivers.
  • Juveniles concentrate in estuaries, seagrass beds, and near sandy beaches; adults range from shallow inshore flats out to depths of roughly 350 meters offshore.

Specific Spots

  • Passes, inlets, and river mouths with strong tidal current are reliable holding areas — jacks use the flow to corner baitfish against structure or the surface.
  • Bridge pilings, jetties, and channel edges concentrate both bait and jacks, especially during moving tides when smaller fish get swept through.
  • Shallow flats and open bays become hunting grounds when schools are actively blitzing — the churning surface activity is visible from a distance and worth running toward.

Crevalle Jack FAQ

Answers from onWater's species guide.

What are the best lures and bait for Crevalle Jack?

Topwater plugs and poppers shine when schools are visibly blitzing, the surface commotion draws strikes the moment the lure hits the boil, and the visual take is part of the appeal.

What flies work for Crevalle Jack?

Baitfish streamers are the go-to: Clouser Minnows (which ride hook-up to avoid snags and imitate a fleeing baitfish) and Lefty's Deceivers (a longer, more lifelike baitfish profile) both draw consistent strikes.

What do Crevalle Jack eat?

Smaller baitfish make up the bulk of the diet, mullet, pilchards, sardines, and similar schooling species, which is why fast-moving baitfish imitations like Clouser Minnows or Deceivers draw strikes so reliably.

Where do Crevalle Jack live?

Native to the western Atlantic from the Canadian maritimes south to Uruguay, including the Gulf of Mexico and Caribbean; also present in the eastern Atlantic from Portugal to Angola and into the Mediterranean.
