Fishermen stunned when they hooked this massive sea beast -- believed to be the biggest of its kind caught on East Coast

Two veteran Massachusetts fishermen thought they’d hooked a shark 100 miles off Cape Cod—until they hauled in a 1,260-pound Atlantic blue marlin. The catch happened Wednesday during a charter trip led by Damon Sacco, who first saw a giant fin breaking the surface and initially assumed it was too pointed to be a marlin. His client, retiree Water Chapman, fought the fish on rod and reel for about three hours, calling it the biggest he’d ever battled. The marlin’s bill caused damage to the boat’s transom. After landing it in Falmouth, the fishermen believe it could be the largest Atlantic blue marlin caught on the East Coast.
