The size of the sharks from Jaws
Weights are calculated using real world shark weights scaled to the shark lengths. However these are low estimates as the film sharks are considerably more bulky and heavily built than a usual great white shark, in addition the Jaws 2 Novel shark is heavily pregnant at the time, increasing her bulk further.
Jaws (Novel) 20-feet-long male, 2.5 tons
Jaws (Film) 25-feet-long male, 4.9 tons
Jaws 2 (Novel) 30-feet-long female, 8.5 tons
Jaws 2 (Film) 25-feet-long female (Practical model is male, but assuming the novel is canon, it's a female), 4.9 tons
Jaws 3D: 35-feet-long female, 13.5 tons
Jaws: The Revenge (Novel) 28-feet-long male, 6.9 tons
Jaws: The Revenge (Film) 25-feet-long male, 4.9 tons
