Taxonomy and classification

Barracudas are ray-finned fish in the genus Sphyraena, placed in the family Sphyraenidae. Sources differ slightly on the total number of living species, but most place it in the range of about 20 to 30 species.

Physical characteristics

Barracudas are slender, torpedo-shaped fish with a large mouth, jutting lower jaw, and sharp teeth. Their body form is adapted for rapid bursts of speed during ambush predation.

Distribution and habitat

Barracudas live in tropical and subtropical marine waters worldwide, with some species extending into more temperate areas. They are commonly associated with coastal environments, including coral reefs, seagrass beds, mangroves, and shallow shelves.

Behaviour and diet

Barracudas are carnivorous predators that mainly feed on smaller fish such as mullets, anchovies, snappers, and similar prey. They often hunt by relying on speed and surprise rather than prolonged pursuit.

Human interactions

Barracudas are generally not considered highly dangerous to humans, though rare incidents can occur, including mistaken bites or injuries involving shiny objects or speared fish. Some species can also be associated with ciguatera poisoning when eaten.
