There were about ten seals floating in the water with their fins up in the air.
It was the weirdest thing! I thought maybe it was a mating ritual. They were all just floating there peacefully with tails and arms and noses in the air. I googled this phenomenon and it seems that they are just trying to cool off! Sticking a fin in the air is similar to throwing sand on one's back, I guess!
But, it did get a lot of attention!
