Today there was no wind and the sea was flat in the morning, like a mirror. In these cases the small fish that live in these parts like to get closer to the shore and if you stirr the sand they arrive to eat what was hidden inside and thus you have a small personal aquarium.
This day was special though since I had never seen so many of them and I even saw a couple that were actually large and sluggish. I even saw a crab skittering in the sand, which I had never seen in 30+ years I’ve been going there.
So, I thought I’d try and take a video:
they were very fun to watch, especially around 0:51 they go full feeding frenzy like small sharks 
Some photos from a few days ago, since I connected the phone to the computer (the three first look like things were today - the other two are from two places a few kilometers away):
