Diving with Barracuda in Bohol
It begins as a silver flash in the corner of your eye. A long, torpedo-like shadow hangs motionless in the blue. Then another, and another, until you find yourself on the edge of a living, breathing vortex of fish, swirling in a synchronized, silent dance. This is the unforgettable experience of diving with barracuda in Bohol.
These sleek, silver predators are a source of deep fascination. With their formidable teeth and intense, watchful gaze, they command a powerful presence on the reef. As your guides to this underwater world, we believe that understanding these impressive creatures is the key to truly appreciating them.
This is your guide to the barracuda of Bohol: one of the fascinating marine species in Bohol you could meet, their captivating behaviour, and where you can witness one of the ocean’s greatest spectacles.

The Anatomy of a Perfect Predator
To appreciate a barracuda is to appreciate evolutionary perfection. Their design is a masterpiece, honed over millennia for speed and precision.
- Body Shape: Their long, streamlined, torpedo-shaped body is a study in hydrodynamics, allowing them to cut through the water with minimal resistance.
- Propulsion: A powerful tail fin provides the thrust for incredible bursts of speed, with some species capable of reaching up to 43 km/h (27 mph).
- The Business End: A prominent, jutting lower jaw is filled with two rows of long, fang-like, and razor-sharp teeth. These are not for chewing but for slicing and tearing, allowing them to prey on fish with surprising efficiency.
- Keen Senses: Barracuda are primarily visual hunters with excellent eyesight. Their large eyes are drawn to movement and reflective surfaces. They also have a well-developed lateral line running down their sides, which detects vibrations in the water, helping them sense prey from a distance.
Bohol’s Barracuda Brigade: The Species You’ll Meet
While you can encounter several types of barracuda in our waters, the experience is often defined by two main species that offer very different encounters.

1. The Main Event: The Blackfin (or Chevron) Barracuda (Sphyraena qenie) This is the star of the show. When divers speak in hushed, reverent tones about the “barracuda vortex” in Bohol, they are talking about this species. While impressive on their own, their power lies in numbers. Blackfin Barracuda gather in enormous schools, often numbering in the thousands. This schooling behaviour is a mesmerizing defensive strategy, making it difficult for predators to single out an individual. To be in the water, on the edge of this swirling, tornado-like mass of silver bodies, is one of the most awe-inspiring experiences in the entire diving world.

2. The Solitary Sentinel: The Great Barracuda (Sphyraena barracuda) The Great Barracuda is a true giant, capable of growing up to 2 meters (6.5 feet) long. Unlike the Blackfin, large adults are typically solitary, and an encounter with one is a very different, more personal experience. You’ll often see these sentinels hanging motionless in the blue, patrolling the edge of the reef with an intense, curious gaze. Their sheer size and impressive set of teeth are a humbling sight and a true privilege to observe.
Curiosity, Not Aggression: Decoding Barracuda Behaviour
One of the most captivating aspects of a barracuda encounter is their intense curiosity. While their formidable appearance might be intimidating, they are not aggressive towards divers. The rare incidents that have occurred are almost always cases of mistaken identity in poor visibility. In the clear waters of Bohol, you can observe their natural behaviour.
You may notice a large Great Barracuda following you during a dive. This is not a sign of malice, but of pure inquisitiveness. You are a large, slow-moving, bubble-blowing creature in their environment, and they are simply observing you.
This is why you’ll often hear the classic advice to remove shiny jewellery before a dive. It’s not about angering the fish, but about preventing a simple mistake. A flash of light from a necklace or ring can mimic the glint of light off the scales of their natural prey, potentially triggering a predatory response based on mistaken identity. It’s a simple precaution for a more peaceful encounter.
Furthermore, when you see a barracuda opening and closing its mouth, it’s a sign of relaxation, not a threat. This action, known as buccal pumping, is simply the fish respiring, passing water over its gills to extract oxygen.
The Hunt for the Vortex: Where to Find Barracuda in Bohol
While a solitary Great Barracuda can be spotted at many of our dive sites, there is one location that stands above all for a truly world-class barracuda experience.
The Epicenter: Balicasag Island The protected marine sanctuary of Balicasag Island is, without a doubt, one of the best places in the world to witness the massive school of Blackfin Barracuda. The dive site known as Black Forest is particularly famous for this spectacle. Here, the school congregates in the deep blue, just off the edge of the reef wall. The experience of swimming alongside this living cyclone of fish is something you will never forget.
While the school is the main draw, the walls of Balicasag at sites like Rico’s Wall and Diver’s Heaven are also prime locations for spotting large, solitary Great Barracuda patrolling the area.
The Role of Your Guide: Witnessing the school is one thing; having a truly great encounter is another. Our expert guides at Sierra Madre Divers know how to read the conditions and the fish. They will guide you to the right spot and show you how to approach the school calmly and slowly, without causing them to flee. A patient, respectful approach results in a much closer and longer-lasting encounter.
A Spectacle of Silver and Speed
Diving with barracuda is a lesson in respect and admiration for a perfectly adapted predator. They are not the villains of reef folklore but a vital and impressive part of a healthy marine ecosystem. To see them in their natural environment, whether as a lone sentinel or as part of a breathtaking vortex, is a privilege.
