Ocean Beach shimmered more than usual this weekend.
Not from the natural beauty of sand, surf and sea, but from a great slick of dead jellyfish that mysteriously washed ashore near Pacheco Street.
More than 10,000 of the gooey invertebrates, each about the size of a dinner plate, drifted onto the beach Friday evening. By Sunday, they had attracted hordes of the curious, the repulsed and the fascinated.
Kids stomped them. Dogs rolled in them. Surfers tossed them at each other. Some people tiptoed fearfully around them, while others pressed in with cameras for close-ups.
"I first saw it and thought, am I hallucinating?" said Nan Madden of San Francisco as she walked her yellow Labrador through the slimy swath Sunday morning. "I've never seen anything like it. I sent pictures to my grandkids."
