The Atlantic bluefin tuna, scientifically named Thunnus Thynnus, belongs to the Scombridae family. It is the largest species of tuna and can reach up to three metres in length and 600 kg in weight.
Bluefin tunas have long, rounded, spindle-like bodies covered in scales. They have large heads and their eyes, compared to other tuna species, are small. Their colouring is deep blue above and silver below. The first dorsal fin is yellowish or bluish in colour, the second is reddish or brownish; the anal fin and pinnules are dark yellow with white rims. These tunas are distinguished by their very short pectoral fins and by a second dorsal fin that is longer than the first. Another stand-out fact is that the bluefin tuna’s body structure makes it a very efficient swimmer.
The bluefin tuna is a migratory species that migrates to seek food and to reproduce. During these migrations, they endure large changes in water temperature, which they can tolerate thanks to their endothermic abilities that help them maintain stable body temperatures.
Bluefin tuna is a schooling and pelagic species, meaning it lives far from land. They can be found both near the surface of the sea and at great depths of up to 1000 meters.
They inhabit the pelagic ecosystem of the entire North Atlantic and its adjacent waters, mainly the Mediterranean Sea.
Their main food sources are fish (primarily herring, anchovies, sardines, Atlantic horse mackerel and mackerel), crustaceans and cephalopods.

Bluefin tuna has been a staple in Mediterranean diets for centuries, thanks to its many health benefits.
It’s high in omega3 fatty acids.
It’s rich in minerals such as selenium, phosphorus and magnesium, as well as vitamins A, B, B3, B9, B12 and D and is an excellent source of proteins of high biological value.
Bluefin tuna also has a very high selenium content compared to other foods, with amounts of up to 17µg/g. Numerous scientific studies show that selenium is highly beneficial for health; it’s a powerful antioxidant and helps neutralise the harmful effects of mercury, which contrary to popular belief, is found in bluefin tuna in much lower quantities than the legally permitted.
Bluefin tuna has a higher protein content than most types of fish and even many meats, making it ideal for children and people who are physically active.
