About
Canned tuna is flaked fish packed tightly into containers, weighing about 6.7 ounces per cup.
Canned tuna has a bulk density of around 50 pounds per cubic foot (0.8 grams per milliliter). The flaked meat leaves tiny air pockets between pieces, which keeps its overall density lower than solid fish fillet. Prepared from species in the mackerel family, it packs more tightly than shredded chicken but is lighter than wet pet food or ground meat.
From Wikipedia
Tuna are saltwater fish belonging to the tribe Thunnini, a subgrouping of the mackerel family (Scombridae). The Thunnini comprise 15 species across five genera, the sizes of which vary from the bullet tuna to the Atlantic bluefin tuna, which averages 2 m (6.6 ft) and is believed to live up to 50 years.
