This predatory fish can grow up to 450 cm in length and weigh up to 680 kg. It has a hydrodynamic, slender and elongated body that ends in a very strong tail. It’s one of the fastest fish, reaching speeds of up to 100 km/h. Its back is dark blue and brown and its belly is silver or light grey in colour. The Swordfish is characterised by a small head with large eyes that can see exceptionally well in the dark. Its long and flat beak is an extended upper jaw. Swordfish live in pairs or small schools and are found almost everywhere. Their main natural habitat can be found in the Mediterranean along the coastlines of Sicily and Malta, while in the Atlantic they are present mainly near South America and Africa, with fewer numbers swimming off the US coast. Most Swordfish close to Slovenia are found in the southern and central Adriatic, and tend to dwell at greater depths.
