Jaws is way larger than your shark, reaching at 7.62 meters long.
Jaws' length: 7.62 m / 45.57 px = 0.1672152732 m/px
Sperm Whale's length 200.99 px = 33.6085977605 meters long
The sperm whale from Jaws: Ultimate Predator is larger than your sperm whale. I'm assuming that sperm whale is a male due to its look.
Male Sperm Whales are around at least 16 meters long and weighs 45 tonnes [metric tons].
Sperm Whale's mass: (33.6085977605/16)^3 * 45 Tonnes = 417.064999164 Tonnes, Class K
Acceptable.
