Ahi tuna and yellowfin tuna are both species of tuna; they are usually mistaken for each other because they have certain similar features. The yellowfin tuna got its name from the bright yellow color of its finlets, second dorsal, and anal fins.
Although both have certain similar features, ahi tuna weigh ways more than the yellowfin tuna. While the yellowfin tuna can grow up to 4000 pounds, yellowfin tuna can grow up to 3000 pounds. In terms of length, the longest ahi tuna can have a maximum length of 250 centimeters in length, while yellowfin tuna can grow up to 239 centimeters.
Another difference is that the ahi tuna has the capacity to adapt to waters with poor oxygen. Also, the ahi tuna has a longer lifespan compared to the yellowfin tuna, meaning they live longer than the yellowfin tuna. The ahis also have the ability to see clearly in turbid waters.
