The Megalodon Shark is considered one of the most dangerous creatures on the planet. It is by far the largest and most powerful fish and one of the biggest hypercarnivorous predators ever known with maximum size theorized to be around 20.3 metres (67 ft) in length and 103 metric tons (114 short tons) in weight.
Megalodon are a pelagic fish that predominantly inhabited temperate and warm water environments. It uses its huge tail or flippers to stun its prey. Based on forensic evidence, its teeth alone are some 6 inches or more long and its jaws around 6 feet wide. That sort of hunter can give even a whale a run for its money and it's been suggested that whale meat was one of its favorites.
Ever since 1918, sightings of these creatures have begun to rise as coastal communities worldwide begin to grow, and shipping lanes become more highly trafficked.
