Tuna is a type of fish that's often eaten as food.
When people talk about tuna, they usually mean something they've bought at the store or caught while fishing - like a can of tuna to make a salad or sushi with fresh tuna from a restaurant. Some people might even go deep-sea fishing to catch tuna, which is then sold in markets or served at high-end restaurants. Tuna's also used in various products like tuna salad, tuna wraps, and canned tuna packed in oil.
Any of several species of fish of the genus Thunnus in the family Scombridae.
