About Bluefin tuna species

Name tuna is very old, and it takes roots from Ancient Greek philosopher and scientist Aristotel. Even in those old times Aristotel was fascinated by tuna's long and fast swimming abilities. Name tuna translated form old Greek would be a "hasty wanderer". There are historical documents from that time that describe tuna fishing in Adriatic Sea, and tastiness of tuna's meat.

Tuna is a carnivore, primarily feeding of small bluefish species like pilchard and mackerel. It is one of the rare endothermic (warm-blooded) fish, and in contrary of dry land endothermic animals it doesn't keep it's body temperature inside narrow margin. Tuna's body temperature changes with water temperature, enabling it to migrate between very different environments, so tuna can be found from warm seas like Mediterranean or Caribbean to the cold coasts of Norway or Labrador.

Their metallic blue coloring on top and shimmering silver–white on the bottom helps camouflage them from above and below. Their torpedo-shaped, streamlined bodies are built for speed and endurance. Even submarine engineers studied their shape and swimming mechanism. They even have several stability fins towards their tail. Bluefin tuna has very effective circulatory system with high hemoglobin concentration and exceptionally thin water-blood barrier that enables efficient oxygen intake.
