Is this a TUNICORN? Fisherman catches bizarre tuna with a horn protruding from its head - but the fish is eaten by a shark as soon as it's released

Veteran fisherman Kim Haskell has been fishing all his life, but he had never seen anything like the catch he snagged while out fishing past Australia's Great Barrier Reef. Kim, 64, a fruit grower, was out on a family fishing trip with his brother Jamie and nephew Christopher near Osprey Reef in the Coral Sea, off the Queensland coast. Christopher reeled in an enormous dogtooth tuna, but it was not that the it weighed in at a whopping 40 kilograms that drew the keen anglers' attention, but the fact that the fish had a giant horn protruding from its head.
