An equally accurate title would be 'Large Hammerhead Shark Oblivious of Florida Beachgoers'

We need to start a program where we fit all sharks with a beacon of some kind and whenever they wander into swimming areas they are picked up by sensors and then a sound system on the beach starts playing the Jaws theme. That will get everyone out of the water in a jiffy.

On the US East Coast, and some other areas, that's actually being done nearly in the way you describe (but the inclusion of a local beach alarm is a great idea). Great Whites are quite frequent over there, and there are a lot of marine biologists who tag them for monitoring, mostly for migrating, preservation and research, but warn local authorities whenever one drifts into pedestrian-laden areas.

Too many people will see this and think 'Oh my god, those people had such a lucky escape, they were nearly attacked!' when in fact the shark was hunting fish and was completely ignoring the people.

It's sad. I sincerely believe those people weren't in danger and yet this video will probably add to people's belief that all sharks are man eaters.

Fair enough to try to better understand sharks and what threat they pose, but to me it's not something you should mess around with in the moment. I think the stingray it was hunting can be quite dangerous too and looked pretty big in that video. Do you think it had chased the stingray that close into the shoreline?

Hammerheads are endangered. They're also my favourite shark.

Quite frankly, I'd rather see the shark eat a few humans than the other way round. We have plenty of humans to spare.... not that many hammerheads.

Besides there are only 34 listed attacks by hammerheads, most of them provoked by idiots and none of them fatal.
