Well, Josh.
Your avatar is certainly appropriate. There’s a theory that goes Jaws actually has a closet ‘supernatural’ element when it comes to ‘Bruce’. Let’s look at the evidence...
There’s Quint’s extreme PTSD from his experiences on the USS Indianapolis. This sets up a direct connection between Quint and the shark that mirrors ‘Moby Dick’, flawed man against the Devil. “Thing about a shark, he's got... lifeless eyes, black eyes, like a doll's eyes.”
This explains Quint’s extreme hatred of sharks and semi-psychotic reaction to the shark in the movie because it does not react the way he expects - for example, being able to “dive with three barells in him”, and hiding under the boat...and when Hooper says, “You ever had one do this before?” Quint just answers, “no...”
There’s the shark’s unnatural size. Whites max out around 20 feet (see below) and ‘our shark’ is around 25ft.
The fact the shark has an unnatural aggression toward the boat... it’s general malevolence, and desire to finish off all three men on the Orca. The shark’s singlemindedness mirrors Quint exactly. There’s a mythic feel about our fish, something that is other worldly, as the original movie voiceover says, “it is as if God created the Devil, and gave him..Jaws.”
