Why do jaguars bite the skull of the prey?

I asked my Friend Rafael Hoogesteijn a Jaguar Expert who works with panthera in el Pantanal, Brazil, he is the author of a very good book in Venezuela named El Jaguar Tigre Americano, he told me that in his humble opinion Jaguars simply adapted to the extintion of large mammals in the plains of South America, they predate surviving reptiles of the American Tropic (with larger biomasses in the banks of rivers), this is the reason of the strong and fulminating bite to the skull of Caimans (Caiman crocodilus and Caiman Yacare), marine and terrestrial Turtles or Green Anacondas; they kill them very fast.
Reptiles are very difficult to kill because they have a second nerve center at the level of the pelvis and for their strong and resistant skins are very hard to kill, he thinks that is the reason why Jaguars have such a powerful bite to the skull different to the other big cats that usually kill their prey biting the throat.
