How can these be real?

Here are two stills from some video I shot at the New York Aquarium on Friday afternoon. Though I’ve been to Coney Island many, many times, I’d never gone to the Aquarium before. Small though it may be, it was a delightful place to visit (not least because of the great blubbering walruses which we all fell in love with)– these jellyfish were so beautiful, and I only managed a couple of short bits of video, as my batteries were waning. I definitely plan to return with a fresh camera. Absolutely mesmerizing.
