Sphyraena sphyraena
The European barracuda (*Sphyraena sphyraena*) is an impressive pelagic predator, known for its hydrodynamic silhouette and aggressive hunting behaviour. Although an emblematic species of warmer Mediterranean waters, in recent years it has been observed more frequently in the Black Sea, as a result of the "Mediterraneanization" process (rising water temperatures). It is the smaller European variant of the famous giant barracuda from tropical waters.
It has an extremely elongated, cylindrical body, resembling a spear. The head is long, with a pointed snout and a prominent lower jaw equipped with long, sharp teeth visible even when the mouth is closed. Coloration is silver-grey on the back, with silvery flanks that may show vertical dark bands, and a white belly. It has two well-separated dorsal fins, positioned towards the rear of the body.
This barracuda is native to the Eastern Atlantic and Mediterranean Sea. In the Black Sea it is considered an immigrant species, found mainly in the south, but isolated specimens can reach the Romanian coast and the Delta in very hot summers. It prefers clear coastal waters near artificial reefs, breakwaters, or areas with strong currents.
It is a solitary hunter (large specimens) or group hunter (young specimens) that relies on speed and vision. The barracuda attacks by ambush or rapid pursuit, using its explosive speed to surprise schools of anchovies, horse mackerel, or mackerel. It is known for its curiosity but rarely poses a real danger to humans in European waters.
Reproduction occurs in warm months (May-August). Females release large numbers of pelagic eggs into the water column, which are fertilized externally. Larvae develop in the open sea, and juveniles seek shelter in shallower coastal areas with abundant vegetation, where they find easy food and can hide from larger predators.
The species is classified as Least Concern (LC). Although not a major commercial species in Romania, the European barracuda is a prized trophy for sport fishermen due to its spectacular fight. Its expansion into the Black Sea is an interesting indicator of climate change affecting our marine ecosystems.
