Great barracuda

Frequently seen hanging over reefs and wrecks; resident year-round.

Barracuda school over the drop-offs at both sites.

Barracuda are reliable around the HTMS Chang and the rocky reefs, sometimes in schools.

Resident on the reef edges and walls year-round; commonly seen hanging along the drop-offs. No seasonal peak.

Barracuda are regular around Pescador and the offshore sites, often near the schooling jacks.

Solitary adults patrol the reef edges year-round; schooling barracuda are a signature of the current-swept Tiran reefs, especially Jackson.

At Blue Corner and Peleliu, often in schools.

Resident; schools of barracuda are a fixture at the bommies (Lighthouse, Steve's, Pixie). Seen year-round.

The chevron-barracuda tornado at Barracuda Point schools year-round (Sipadan closed in November).

Standard around the bait crates and over Sugar Wreck year-round. Draws to the bait alongside groupers and snappers; incidental to the shark diving.

Regularly hang over the larger hulls and superstructures.

Seen around the Liberty wreck and the Penida drop-offs, sometimes in schools.

Large solitary barracuda along the walls and dense schools at current-swept points like Mandolin and Sachiko's.

Juveniles are reported in the brackish, tidally connected channel at Casa Cenote, which links to the sea — the only cenote in this region where a marine predator turns up. Not present at inland or enclosed cenotes. No seasonal pattern documented.

Barracuda pass by the deeper wrecks such as the Kogyo Maru; the animals that gave Barracuda Lake its name are now rarely seen there. Occasional rather than reliable.

Seen along the pass edges and drop-offs, solitary adults hanging in the current and sometimes loose groups. Regular but not the signature schooling spectacle that Rangiroa's Tiputa pass is known for.

Seen singly or in loose groups over the reef drifts; a regular but not guaranteed sighting.

Barracuda school at the wreck and pinnacles; a chevron barracuda school reportedly circles divers on the Yong Hua ascent.

Seen around pinnacles and reef sites; large schools of chevron barracuda are a feature of Sail Rock and Chumphon Pinnacle in particular.

Barracuda hang around the King Cruiser wreck and Anemone Reef pinnacles, sometimes in loose schools.

Barracuda, including schooling fish, are seen along the current sites of the Verde Island Passage such as The Canyons.

Great barracuda and schooling chevron barracuda are common at pinnacle sites like Koh Tachai and Richelieu Rock. Present through the open season.

Barracuda school at the pinnacles and islet points; single large barracuda are common on the reefs.
