Global adventurer Josh Gates solves some of the strangest and most disturbing shark mysteries of all-time, including the real-life bloody inspiration for the movie Jaws and the gruesome case of the Tiger Shark who vomited an arm while living in captivity and ultimately helped police solve a murder mystery. 

Wildlife biologist Forrest Galante injects himself with shark venom after diving down under into Australia's dangerous waters, home to some of the weirdest, alien-like and deadly sharks.  He hopes this risky and potentially lethal experiment will bypass years of red tape to finally discover the potency of the venomous Port Jackson Shark and Ghost Shark.
