The tuna (マグロ, Maguro?) is a rare fish that can be found in the ocean at any times of the day between the months of November and March. The fish sells for 7,000 Bells at Tom Nook's store, which makes it the second most expensive winter fish after stringfish.
Donation to the museum
In Wild World
Blathers will say this when donated to the museum: "If a tuna stops swimming, it will stop breathing and expire, eh wot? As you can imagine, this means that it must swim when it sleeps as well. I think every day about how marvelous life would be if I could work in my sleep!" One can find the tuna in the back tank with the other ocean fish.

Upon donating to the museum, it can be found in the back tank with other ocean fish. When given the fish, Blathers will say this: "If tuna stop swimming, they actually lose the ability to breathe and can perish! ...Which means that even while resting, this fish just keeps swimming, eh wot? I really prefer to focus on resting up rather than napping... Rather lucky I was born an owl, wot wot!"
In New Leaf
In New Leaf, an information board in the aquarium will list information about this fish.
"Tuna can reach almost 10 feet in length and weigh over 800 pounds, which is huge in the fish world. Combining this great size with their good flavor makes them literally the biggest catch for most anglers. Tuna can't breathe when they aren't moving, so their entire lives revolve around constantly swimming. To sleep, they merely slow down. This ability to swim while sleeping is a huge advantage. They're also rather fast, capable of beating both sets of fins so hard they reach speeds of 50 mph."

There are various types of tuna in existence. As a result of its uses, it has become overfished and due to its late maturity, it is increasingly difficult for it to reproduce to sustain the demand. It is currently classified as Critically Endangered due to its rapid decline, which is the last level before Extinct. It preys on squid, crustaceans, horse mackerel, and other small fish.
