Crocs usually die or get shot in remote locations where suitable machinery for handling and weighing their large carcasses is seldom available. Most locations are not only remote, but warm as well, so tissue rots (and stinks) rapidly. There are therefore very few data on body weight of the largest animals, and even many of the length measurements are open to question (crocs grow with each telling of the story).
