One Massachusetts fisherman came back with a whale of a tale after a diving trip last week. Diver Michael Packard told the Cape Cod Times he became trapped inside the mouth of a humpback whale after he jumped into the waters off Cape Cod one Friday morning. The 56-year-old was heading towards the bottom of the seafloor to grab lobsters when he says he was suddenly engulfed in darkness. Packard told the Times he initially believed he was being eaten by a great white shark, but could not feel any of the animal's teeth. After 30 to 40 seconds, the whale surfaced and let Packard out of its mouth, he said. The incident was reportedly witnessed by Packard's mate, Josiah Mayo, who retrieved him and called for help. In an interview with WBZ-TV, Packard said all that crossed his mind for those few desperate seconds was how he was going to make it out of the situation alive. "It was happening so fast," he said. "My only thought was how to get out of that mouth." Fortunately, other than experiencing the ride of his life, Packard was in no danger of being eaten. Humpback whales mainly feed on squid, krill, salmon, and other small fishes.
