Sphyraena obtusata, commonly known as the striped barracuda, is a widely distributed species of barracuda found in tropical and subtropical waters. It is characterized by its elongated, cylindrical body, pointed snout, and prominent teeth. While generally smaller than some of its more formidable barracuda relatives, it is still an efficient predator, often found in schools.
Physical Characteristics
- Body shape
- torpedo
- Coloration
- Dorsal side is typically greenish-grey to dark blue, fading to silvery-white on the flanks and belly. Often exhibits faint, dusky vertical bars or a yellowish lateral stripe, especially when young or stressed. The caudal fin is often yellowish.
- Scale type
- cycloid
- Mouth position
- superior
- Distinctive features
- Elongated, cylindrical body, Pointed snout with a large mouth, Prominent, sharp, canine-like teeth of varying sizes, Two widely separated dorsal fins, Yellowish caudal fin (especially in younger individuals or certain populations), Often a faint yellow stripe along the lateral line
- Dorsal fin
- Two widely separated dorsal fins. The first dorsal fin has 5 strong spines, and the second dorsal fin has 1 spine and 9 soft rays.
- Tail fin
- Forked caudal fin, often yellowish.
- Pectoral fin
- Short pectoral fins, typically not reaching the origin of the first dorsal fin.
- Distinctive fins
- Pelvic fins are abdominal, located beneath the pectoral fins.
Identification Tips
Body Shape and Coloration
Look for the classic barracuda torpedo shape, silvery body, and often a yellowish caudal fin. Faint vertical bars or a yellow lateral stripe can be present.
Dorsal Fins
Note the two distinctly separated dorsal fins. This is a key barracuda characteristic.
Pectoral Fin Length
The pectoral fins are relatively short and do not extend past the origin of the first dorsal fin, which helps distinguish it from some other barracuda species.
Mouth and Teeth
Observe the large mouth with prominent, sharp, canine-like teeth. The lower jaw typically protrudes beyond the upper jaw.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow coastal waters, from the surface down to about 30 meters (100 feet), though occasionally deeper.
- Environment
- Inhabits a variety of coastal environments including coral reefs, rocky reefs, seagrass beds, estuaries, and open coastal waters. Often found near structures or schooling in open water.
- Geographic range
- Indo-Pacific region, extending from the Red Sea and East Africa across to the Central Pacific, including Australia, Japan, and Hawaii. Also found in parts of the Eastern Atlantic, including the Mediterranean Sea (likely via the Suez Canal).

- Temperature: 72-78°F (22-26°C)
- pH level: 8.1-8.4
- Hardness: 8-12 dKH
- Compatibility: Not suitable for community tanks. Best kept alone or in very large, species-specific displays with other large, fast-moving predatory fish that cannot be eaten.
- Special requirements: Requires a very large tank with ample swimming space. Excellent filtration is essential due to their predatory diet. Live or fresh dead fish should be offered. Can be prone to stress in smaller enclosures.
Wild Information
- Conservation status: least concern
- Seasonality: Present year-round in tropical and subtropical habitats, but local abundance may vary with seasonal prey availability and water temperature.
- Market price: Varies regionally, generally moderate.
- Commercial importance: medium
- Taste: Mild, firm, white flesh.
- Texture: Firm, flaky.
- Cooking methods: Grilling, Baking, Frying, Steaming
- Nutritional value: Good source of protein and omega-3 fatty acids. However, larger specimens in certain regions may carry a risk of ciguatera poisoning.
Key Facts
Schooling Behaviorbehavior
Unlike the solitary Great Barracuda, Striped Barracudas often form large schools, especially when young, providing a striking visual in their natural habitat.
Cosmopolitan Distributionamazing
Sphyraena obtusata boasts one of the widest distributions among barracuda species, spanning vast areas of the Indo-Pacific and even entering the Mediterranean.
Ambush Predatorbehavior
While often schooling, individual Striped Barracudas are still formidable ambush predators, relying on their speed and sharp teeth to capture prey.
Ciguatera Riskinteresting
Although generally smaller, larger individuals of Sphyraena obtusata, particularly in certain tropical areas, can accumulate ciguatera toxins, making them potentially unsafe for consumption.
Safety Information
Handle with care- Safety level: caution
- Venomous: No
- Edibility: not recommended
- Handling notes: Barracudas possess extremely sharp teeth and can inflict severe bites if provoked or mishandled. Exercise extreme caution when handling, especially if caught by anglers. Use appropriate tools (pliers, dehookers) to avoid direct contact with the mouth. Larger specimens, particularly in certain tropical regions, can carry ciguatera toxin, making their consumption risky.
Similar Species
Great barracuda
Sphyraena barracuda
Sphyraena barracuda grows significantly larger (up to 2 meters), has irregular black blotches on its lower flanks, and often has a more pronounced, darker caudal fin. Its pectoral fins extend beyond the origin of the first dorsal fin.
Pickhandle barracuda
Sphyraena jello
Sphyraena jello typically has more distinct, dark, wavy vertical bars or chevron-like markings on its sides, and its pectoral fins are also relatively short, similar to S. obtusata, but the body markings are a key differentiator.
Blackfin barracuda
Sphyraena qenie
Sphyraena qenie has a darker, often blackish, caudal fin and typically lacks the yellowish tint seen in S. obtusata. It also tends to be a larger species.
