Who did Steven Spielberg name the shark after in the film "Jaws"?
Bruce was a shark, the main antagonist in the "Jaws" film franchise, and was the collective name for a reoccurring group of supposedly mutated Great White Sharks thought to be closely related genetically.
This particular incarnation of the shark was depicted in the film "Jaws" released in 1975. In addition, there were slightly similar looking designed sharks depicted in follow-up sequels (Jaws 2, Jaws 3-D, and Jaws 4 respectively). However, the shark design as depicted in "Jaws", is by far the most respected variant among aficionados of the film franchise.
Because the shark was originally called "Bruce" by film crew members in reference to Steven Spielberg's lawyer, Bruce Raynor, knowledgeable fin fans tend to prefer using this as an official moniker.
Bruce was around 25 feet long and weighed around three tons. Oddly, Bruce had noticeable jowls, a feature it also shared with other great whites that appeared in the film franchise. Bruce could easily bite through a leader on a fishing line made of steel piano wire, and smashed the hull of the ORCA with it's great strength.
