Tuna is a wonderful way to get omega-3 fatty acids, which the human body can't produce by itself.

That will stock your freezer for the winter! A tuna can grow anything from 3 feet up to 10 feet according to the tuna type and the fish itself.

The tuna fish belongs to the family scombridae.In this family there are more than 48 species of tuna which are divided into five smaller groups: Thunnus, Euthynnus, Allothunnus, Auxis, and Katsuwonus. The tuna is a carnivorous fish.


Tuna Fun Facts!

  • Though Tuna looks kind of lazy fish the tuna can swim very fast,70 kilometers per hour!
  • Most tunas are designed to be camouflaged in the ocean-- the back is dark to blend with the color of the ocean depths when you look down on it from above, while the belly is light to blend with the ocean surface when you look up at it from below.
  • Despite the fact that fish are cold blooded by definition, tunas can be classified as warm blooded because they're able to maintain a body temperature a few degrees above the surrounding water.
  • Tunas have to keep swimming so they can get oxygen from the water-- they can never stop!
  • The average tuna lives 15 to 30 years.
  • One female tuna during spawning season can release up to 30 million eggs!

Types of Tuna

When we talk about the tuna types we talk actually about the fish in the Thunnus genus-- these are considered 'true tuna' and the type of tuna we eat fall under this category. These species are: Albacore,Yellowfintuna, Blackfin Tuna, Pacific Bluefin Tuna, Northern Bluefin Tuna, Southern Bluefin Tuna,Bigeye Tuna and the Longtail Tuna.

The smallest the answer is the bullet tuna and the largest is the northern bluefin tuna.

When one open a can of tuna most chances it will be Albacore and the meat of that tuna is the only one with the right to legally be called 'white meat'.

The meat of the bluefin and yellowfin is also commercial, most commonly found prepared in sushi. When eating a bluefin you will find it to be with strong yet flavorful taste-- it is considered a delicacy.
