Sphyraena qenie
Silvery pelagic hunters logged across Sulawesi, Palawan and Queensland reefs, comfortable year-round in warm 24-29C water.
A long, torpedo-shaped body reaching around 118 cm, silvery along the flanks with a slightly darker back and the dark-tipped fins that give it the name. Look for the elongated, pointed snout and the underslung jaw lined with visible teeth, held nearly motionless in the current. Unlike smaller barracuda species it tends to hold station alone or in loose groups rather than tight, spiralling schools.
Usually spotted hanging in open water just off the reef edge or over a drop-off, holding position facing into the current rather than actively chasing prey. Divers most often log it as a solitary or loosely grouped sighting rather than in the dense, wheeling schools some other barracuda species form. It tends to keep a cautious distance and rarely shows any interest in divers beyond a curious look.
As a carnivore built for open-water ambush, it relies on speed and a sudden lunge rather than pursuit, which is why it so often appears to be simply drifting until a baitfish strays too close.
No strong seasonal pattern shows up in sightings, and with a comfortable range of 24.4 to 29.3C across its reef habitat, it's a fair bet on tropical reefs any month of the year.
Reef neighbours a diver could mistake it for. Use the identification notes above to tell them apart.
Most reliably logged across Indonesia and the Philippines, with strong numbers in Sulawesi, Palawan, Luzon, Visayas and Mindanao, plus Kalimantan. Queensland in Australia is another consistent spot, and it also turns up regularly in Sabah (Malaysia), Thailand, Micronesia, Vietnam and Palau.
Mapping where Blackfin Barracuda is logged…
Indonesia and the Philippines are the strongest bets, particularly Sulawesi, Palawan, Luzon, Visayas and Mindanao. Queensland in Australia and Sabah in Malaysia also produce regular sightings.
There's no clear season in the sighting data, and the water temperatures it favours (roughly 24 to 29C) hold across the tropics year-round, so it's a possibility on any dive in the right region.
Look for a long silvery body around a metre or more, a pointed snout with visible teeth, and dark tips on the fins. It's usually seen alone or in small loose groups holding still in the current rather than schooling tightly.
They typically reach around 118 cm in length, giving them a noticeably long, streamlined profile compared to smaller reef barracuda.
No, they're not considered dangerous to divers. They generally keep their distance and are more curious than confrontational.
