There are certainly different qualities that make fish worthy of pursuit. Some are beautiful, some are delicious … but then there are the fish that are just mean. There's something about chasing a creature you're partially afraid of that's exhilarating. We ranked the fiercest 40 fish based on a few factors. The first was their fighting ability pound for pound. The second was what danger they posed to you and your tackle. The third was how menacing they looked, and lastly their size (also, we included sharks, which are not technically fish but they're pretty dang close). Here's our 40 fearsome fish. See which one took top honors at number 1 and let the debate begin. 40) Swordfish: They can grow to 15 feet and 1.5 tons. They're a perfectly designed brawling machine. It uses its bill to kill its prey. Their majestic and mean, and tremendous fighters when hooked. 39) Roosterfish: There's something menacing about seeing that comb cut through the waves as a rooster slices through the ocean effortlessly chasing bait. They can exceed four feet in length and grow to more than 100 pounds. You'd better bring your best gear if you're going after them, and even then they might leave you muttering. They're muscular, fast and vicious. Photo: Halpochromis 38) Striped Bass: A big striper will chase down a bluefish. That takes tenacity. They'll destroy your best lures, inhale your eels, mangle your mackerel, and swim right into crashing breakers to take a bait. There's no doubt once you've seen a school of stripers mauling a bunch of baitfish they've got pinned against a jetty or sandbar… they're mean. 37) Largemouth Bass: A ten-pound bass will have no trouble mangling even your strongest spinnerbait. They'll crush topwater lures, fight you every inch of the way to the boat, make violent jumps when hooked, and have been known to attack ducklings, mice and rats if they get hungry enough. https://www.outdoorlife.com/photos/gallery/fishing/2011/03/40-meanest-fish/
