Is The Shark In This One The Same Shark From The First Film?

From what I understand from what I have heard of the novelizations of Part 2 plus Revenge this shark is supposed to be the child of one of the sharks from the first two films, or perhaps the child of both of them. So it was a family move in a way; a family of sharks, a family of Brodies, and their resulting feud over who "owned" Amity which was the basis for the revenge.

Anybody want a peanut ?

I really can't figure out what the film is trying to say, i.e., its "message", if it had one at all. It does seem that a certain miniscule group of sharks had it in for the Brodys after the Chief killed the first one. I can see how the "shark family" model could work - a tiny group of sharks, somehow linked by (mammalian?) family feeling, or by some kind of fish telepathy, went on a vendetta against the Brodys. But of course, then the question becomes: Why the Brodys and not any of the thousands of other people who kill sharks?

Maybe the best explanation is a type of non-explanation based on the supernatural premise that, as Ahab theorizes in Moby Dick, there is a malignant "Power" lurking behind the pasteboard masks of living creatures, a force that has plagued mankind since the beginning of our species. It wasn't the "dumb beast", the White Whale itself, that Ahab hated - it was the malignant Power that operated in and through the whale. Perhaps the same kind of thing applies to the Jaws films as a connecting thread.

I think the film is more trying to say something like "Lookie at what our first year film student can do!"
