I'd never seen a jellyfish outside of an aquarium. I watched some more, noticing that it had started to drizzle a bit and drops were hitting the still surface of the water.
Wait....those weren't drops. It wasn't raining. That was the water surface moving because there were more jellyfish.
I realized that there were thousands of them, as far as I could see, just drifting, pulsing slowly as they do. A jellyfish ballet right outside my window. It was mesmerizing.
And then Miss C spotted this fellow, off a ways under the surface of the water so it was hard to see him clearly:
We think it was a Lion's Mane jellyfish.
Good thing we weren't going swimming. But what a magical sight!
