There are about 8 species of hammerheads.

I saw a photo of that head and it looks like the smooth hammerhead.

Smooth hammerheads get as far north as mid California.
If that shark specie did swim into your area it would be very unusual. - Tom

There have been sightings of Great Whites this far north though very rare. Probably following the California Sea Lions up here when they feed on our returning salmon. I suppose if it’s possible for a Great White it is possible for the Smooth Hammerhead, if that is indeed the species.

Thanks for your knowledge on the subject.
