 It's amazing that it syncs up with the moon, which causes such gravitational pull as making a flat ocean turn into 20- and 30-foot tides and big waves. And sea life can evolve to the point of understanding the highest tide and the highest wave and peak of the tide of the spring to go lay their eggs where it will be above any other water that will come up. So they can survive all this tide together. I'm sure you've looked at a lot of all that.
