We present the case of a non provoked fatal shark attack on a 19-year old male surfer in New Caledonia. Several severe bites removed the right arm and all flesh from the right thigh, provoking a quick hypovolemic shock that was fatal. The information provided by a witness and the analysis of a partial bite on the right calf allowed us to identify a 2.7 m TL (est. length) white shark as responsible for this attack. The features of the attack are consistent with a young predator motivated by hunger and the development of its predatory skills.
