Even when we have home field advantage, a beached shark is still not something you want to see on a relaxing trip to the playa. Because, for one, the shark baring its teeth and whipping its tail is still scary as hell even though it shouldn't be able to reach you. But, more importantly, because we're humans with hearts and some semblance of a soul, we would want to rescue the shark which means we have to bring it to their territory -- back to the ocean.
It's all a ploy you see. Smart shark feeds on soft humans. This footage taken by Mike Bartel shows the beached shark flailing around until its saved by the harbour master and generous beach goers.
