By measuring the head of one which was accidentally caught in nets, and noting positions and leverage angles of structures and muscles, they say they can work how much force the shark can apply.
Surprisingly, they expect the great white to have a less forceful bite than a tiger or bull shark, when size is taken into account.
'The white has the narrowest head of the three, so it has less space for jaw muscles,' said biologist Daniel Huber. 'Consequently, we're expecting that it will have a lower bite force on a pound-for-pound basis.'
