Other forms: tunas
Tuna is the big sea fish sold as fresh steaks or packed into tins. Dark red raw, pale and flaky cooked.
It is one of the fastest fish in the ocean and one of the most heavily fished, which is why tins carry labels about dolphin-friendly nets and sustainable sourcing. Bluefin is the prized and threatened kind. The word works as a mass noun, so you buy tuna rather than tunas, though biologists use the plural for species. A tuna melt and a tuna mayonnaise sandwich are the everyday dishes.
1nountunaA large sea fish eaten fresh or tinned.
