Nebula? -No algae!

I thought this was rather interesting..

 

Pretty cloudy here still, so I grabbed a waterproof camera and stuck it in the shallows of Puget Sound. This is a crop, so not super hi rez, but doesn't it look remarkably like a nebula?

 

Maybe just a coincidence, but it does make me wonder if some similar mechanism is at play despite the differences.
