The first Jaws was a killer of opportunity much like a real shark. It was later sharks under the title which began to exhibit tenacity for specific targets.

Still, when a predator gets a prey's scent, they can lock in on it and follow for a long time. Like bloodhounds tracking one specific scent. Or pets which cross country to find their owners (skip the first one, she had help).
