I think the bigger story is that hammerheads aren’t known to be in our waters - it’s he warm El Niño conditions (74F surface water temps ) that have been bringing in Sea of Cortez type animals the last two years
They are freaky looking, but as someone mentioned upthread, there are worse threats to surfers and swimmers among shark species than a hammerhead. They’re really not know to attack humans all that often.
Not true. I've seen 10 footers fishing off barn kelp in San Clemente. El Nino is happening though. Last summer we were catching dorado off Oceanside. Even wahoo off san diego were reported.
