@badsaac: Those little finlets don’t just make ‘em absolute missiles in a straight line; they’re a row of tiny rudders. When a longtail needs to execute a violent, high-speed turn on a baitfish, it alters its body pitch. The finlets instantly act like micro-canards, controlling the water vortexes so the rear of the fish doesn’t wash out or break traction. Paired with stiff caudal keels acting as stabilizers, the tail gets immediate, high-grip purchase on the water. Instead of skidding, the tuna gets instantaneous hydrodynamic bite—pivoting its trajectory mid-run without losing an ounce of momentum. Drop a 🎣 if you’ve seen these missiles switch gears in real life! #LongtailTuna #TunaFishing #FishFacts #OffshoreFishing #Pelagic
