When I was a kid, we lived in Key West for a few years. I would ride my bike down to the docks on Saturday afternoon
and watch the party boats bring in their haul. They were right on the main road into Key West, so had boards rigged
with spikes, slap all the fish on the boards in a big display while the crew started fileting them for the fisher folk to
take home. One or two boats would often bring in a big hammerhead, say 10 ft or more or a big jewfish, similar in
size and appearance to your first photo. They have slightly larger mouths, proportionally. Of course, jewfish became
politically incorrect and recently they were renamed goliath groupers. Whatever, I saw a bunch of 300-400 lb "sea bass"
hanging up there as a kid. Still impresses me.
Slums are slums, no dead horses, but probably dead people in places in current big cities. Stories out of
SF, as Gary mentions are pretty ugly. Hope to not need to go back, ever.
