Military Barracuda

Sphyraena putnamae

Also known as Sawtooth Barracuda, Chevron Barracuda

Military barracudas cruise shallow coastal reefs and murky lagoons, often assembling in disciplined, spiraling schools by day before dispersing into solitary hunters at night. Equipped with binocular vision and formidable dagger-like teeth, they strike unsuspecting prey in sudden bursts exceeding forty kilometers per hour. Their striking chevron pattern breaks up their silhouette against undulating sunlight, making them nearly invisible to smaller schooling fish until the moment of ambush.
